The document discusses the environmental issues caused by mining of Kota stone in Rajasthan, India, including the loss of over 900 hectares of prime agricultural land and dumping of waste on additional farmland, as well as proposals to better manage waste and minimize environmental damage such as refilling mines and conserving topsoil. Kota stone deposits cover around 150 square kilometers but reserves may be depleted within 15 years given the current production levels and practices.
Kota stone slurry problem and possible solutionsAkhtar HUssain
India has largest reserves of dimensional stones in the world and this makes suo-moto largest producer of dimensional stones in the world. We have a wide spectrum of dimensional stones including Granites. Marbles of different colours and textures, Sand stone, Lime stone, Slates and Quartzites spreaded all over country.
The recent trend of converging focus on environmental issues, corporate social responsibility (CSR) and inter-related other issues have taken a prime space in the navigational system of mining and quarrying activities world-wide and India is not an exception. The main philosophy is that these measures would mitigate or lessen the severity of the negative impacts of mining on the local environment and social trauma. Mining and quarrying at large are supposed to affect local hydrology, produce harmful impacts of air-borne dust, land degradation, divertion of surface drainage pattern, water pollution,loss of valuable top soil and vegetation cover. In fact mining becomes a major
source to alter the local ecological balance of habitats and landscapes. On the other hand post mining not only leaves some waste dumps but also awfully fearsome post extractive sites. One very important non tangible aspect of the mining process is noticeable impact over local social dynamics in both directions including sustainability of livelihood and damaging issues running concurrently at all stages commencing from the point of mine operations
commencement, end of mining activities and post mining closure .Socioeconomic impacts of mining activities may be divided into two groups viz,individual workmen related which cover working and living conditions, the health, issues of child and women employment, education, welfare etc and
community related which cover, role of migratory workforce, mechanization,change of land values and titles, women employment etc.
Mineral deposits of potential economic significance in Sinai:; Most of the metallic and non-metallic deposits are found in the Middle Western portion of South Sinai, close to the Gulf of Suez.

The southern Indian granulite terrane is known for granulite - facies rocks which is formed during the ‘Pan-African orogeny.
The region is composed of Neoproterozoic to Cambrian crustal blocks, dissected by large-scale shear zones (Palghat-Cauvery and Achankovil).
The Palghat-Cauvery Shear Zone System (PCSZ), separates the terrane into two parts, Archean Dharwar Craton in the north and the Neoproterozoic Madurai Block in the south.
The southern margin of this block is defined by the Achankovil Shear Zone.
Geology of the study area
The Achankovil Shear Zone (ACSZ) is major lineament of 8-10 km width and >100 km length.
The rocks in the zone display a prominent NW-SE trending foliation with steep dips to southwest.
Estimation of pressure and temperature (P-T) of this lithology was first carried out by Santosh (1987) based on conventional geothermometers and mineral equilibrium, that gave 700-800◦ C at 5.5-7.0 kbar.
Later study done by Nandakumar and Harley (2000) which is slightly higher 925 ± 20◦ C at 6.5-7.0 kbar .
3.1. Grt- Opx- Crd Gneiss
The Grt-Opx-Crd gneiss is a coarse-grained, granulite-facies rock with a probable pelitic protolith.
The mineralogy of a representative sample (KR19-5G1) is plagioclase (30-40%), ortho-pyroxene (20-30%), garnet (10-20%), K-feldspar (10-20%), quartz (5-10%), and cordierite (2-5%) with accessory of biotite, spinel, and sillimanite (Fig. 2a).
Garnet is very coarse-grained (3-6 mm) ,subidioblastic, and contains numerous fine-grained inclusions of sillimanite (0.05-0.2 mm), biotite (0.05-0.4 mm), spinel (0.05-0.1 mm), and quartz (0.05-0.1 mm).
The most significant feature of this rock is the direct contact relation of fine grained spinel and quartz (Spl + Qtz), which occur only as inclusions in garnet.
Spl + Qtz association has been regarded as one of the indicators for decompression at UHT conditions. This is the first finding of such an assemblage from the ACSZ.
PRIMARY GEOCHEMICAL HALOES IN PROSPECTING FOR GOLD DEPOSITS, UMM RUS MINE, EASTERN DESERT, EGYPT
The estimated Au values in the Umm Rus deposit are found to be dependent, besides physico-chemical factors, on the dip angles of the housing fractures and the amount of wedging-out of the quartz veins. The highest values are anticipated in the thin-gently dipping quartz veins which are commonly detected in some parts of level-279/ and level-487/. A stepwise discriminant analysis was used to reduce a number of potential pathfinder variables to an optimum group of pathfinder variables that differentiate between mineralized and unmineralized quartz vein samples.

Sedimentological and Palynological Approach for Determining the Depositional ...Md. Yousuf Gazi
Sitakund anticlinal structure exposes about 1.5 km of Surma group sediments and has been chosen for a comprehensive study of the
mudrocks depositional environment based on sedimentological and palynological evidences. Five mudrock facies have been identified in
this region. They are Mudstone Dominated, Sand/Silt Streaked Shale, Fissile Shale, Laminated Shale and Lenticular Bedded Shale. The
palynological assemblages from these samples have been analyzed qualitatively, and a variety of pollen, spores, algae and fungi identified.
The pollen and spores have been attributed to parent plants located at the immediate and more regional surrounding areas during the
deposition of these sediments. Palynological assemblages incorporates ample of Palmae grains such as spores in the Palmipollenites and
Proxaperites and predominance of pteridophytic spores. The occurrences and abundances of these pollens indicate that the deposition of the
Surma mudrocks took place at the proximity of the shore level. Coastal fluvial environment is also triumphed after the previous depositional
event which is apparent by the occurrence of palynomorphs of pteridophytes, angiosperms and algal origin.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Kota stone mining – environmental issues
1. KOTA STONE MINING – ENVIRONMENTAL ISSUES
A. Hussain
Mining industry is one of the most important and old industry supporting the
country’s economy. The present trend is to opt for opencast mining in place of under
ground mining. At present country’s 25 lakh hectare area is under mining lease
conditions, out of which ninety percent area is subject to opencast mining techniques.
In general, all the mines affect their surrounding environment to a little or more
extent, but opencast mining in particular lead to complex nature of environmental
problems. In these circumstances it became imperative to mine planners and operators
to plan and execute mining programmes in such fitting manner so that the impact of
mining on the local environment is brought to a negligible state or preferably to a
zero level. This requires a careful planning as well as more attentive work execution
on day to day basis. Impact on the local environment is more aggravated and complex
in case of small mines exploiting minor minerals such as marble, granite Kota Stone,
sandstone and other type of building stone quarries.
Kota and Jhalawar districts of Rajasthan have been subsisted with about 100
million tonnes of splitable type of decorative grade flooring limestone, better known
as Kota stone. A typical chemical composition of Kota stone is given in table-A
Table – A
Kota Stone Chemical Composition
S. No. Chemical Constituent Percentage (weight)
1 Calcium Oxide 37.30
2 Magnesium Oxide 4.13
3 Sodium Oxide 1.21
4. Potassium Oxide 0.40
5. Aluminium Tri Oxide 1.37
6. Ferrous Oxide 0.86
7. Titanium Di Oxide 0.05
8. Silica 24.90
9. Loss on Ignition 32.94
These deposits are part of vindhyan range of sedimentary rocks, overlain by sand
stone cappings. In general Kota stone mining areas are free from sand stone coverings
and the entire profile consists of different grades of lime stone beds. The floor grade
limestone is available in a variety of different colors including blue, green, brown or
spotted type. Color pattern is governed by the chemical composition where main
players are iron, Titanium and Aluminium.
Kota stone formations outcrop in varieties of colours, predominantly blue, green,
brown or their combinations etc. At place calcitic veins are are distinctly criss-
crossing the deposits. Soil subsoil and non splittable lime stone layers are overlying
these deposits.

longitudes E 75o 50’ and E 76o 05’ and it is covered on topo sheet No 45/D/13.
45/D/14, 54 D/1 and 54 D/2.
The various Kota Stone laminations are nomenclatured locally in an uniform
language. Geologically Speaking, Kota Stone is part of Semi Series of lower
Vindhyan group. The local nomenclature are well understood and prevailing from the
inception of the mining in this area. The regional stratigraphic sequence of the deposit
is given in table-B

The workable lime stone beds ameanable to splitting are located at a depth range
from 15.0 mtrs to 25.0 mtrs from the surtace and form part of anticlinal- syniclinal type
of sedimentary laminated structures.
Strike and Dip of the deposit is primarily location specific, but generally the
deposit dip at 7.5 percent away from the anticlinal – synclinal common axis. The
limestone bed is divided into five prominent sacks which are separated from each other
by clay partings. Thickness of Laminations in each sacks increases with depth and texture
also improves. However the lamination thickness and texture improves with higher Silica
fractions in the sacks, as given in table-D.

Stratigraphic profile also varies from place to place and can be divided into three
categories depending upon the type of waste material overlying the workable deposits,
viz.
1. Overburden Comprising soil, sub-soil and mixed calcareous - like chechat area.
2. Overburden Comprising soil, sub-soil and Basalt rock-like Pipakheri, Zulmi area.
3. Overburden Comprising soil; sub-soil to a large extent underlain by a narrow
band of calcareous rocks-like Jhalwar district deposits.
The stratigrapic rock profile of all three deposits are shown in Table-E.

Semi mechanized mining method is usually adopted, where the overlying waste
material is removed with the help of hydranlic excavators having bucket size 0.5 to 0.9
cu. meter and tippers of 10.0 to 15.0 mt bucket capacity. Hard overburden is drilled with
125 mm size water-hole drilling portable rigs. The drilling pattern in the soft rocks is
maintained at 4.0 x 4.5 mtrs, while in Basalt it is narrowed down to 3.0 x 3.0 mtrs
Mixture of conventional cartridged explosives and ANFO is used for blasting. In Basalt
the charging factor is kept at the rate of 1.25 kg per foot of drilled hole length, while in
other cases it is 0.8 kg/foot of drilled length of hole. Radiat blasting techniques is used in
the sensitive areas, while at other places 17 ms relays are used to provide relief between
detonating rows.
The workable tables are given 150 mm to 450 mm deep cut channels at an
interval of 0.6 mtrs distance with the help of electric motor driven Jhirri machines. Semi-
Skilled artisans, cut and size different length of slabes from these bays and stack at
designated places, from where the slabes are loaded into trucks and transported to sales
stock, maintained at quarry top. This entire operation is manually operated.

The average yield of acceptable quality of Kota Stone per hectare land area is
about 1.00 lakh M.T, and with the current trend of yearly production level, 55.0 to 60.0
hectare land is brought under stone mining each year. In all cases this land belongs to
farming sector and is completely degraded as far as agriculture is concerned. In a rough
4
5. estimate, till date almost 900 hectare prime agriculture land has been lost to Kota Stone
mining alone in Kota and Jhalawar districts. Damage to land surface from sand stone
mining is not included in this assessment.
In addition to the environmental problem cropping up due to permanent loss of
prime agricultural land, there is one more dimension to this activity i.e. formation of
waste dumps over agricultural land. Most of the mining leases are of 4.0 Ha to 25.0 Ha
size areas, where side by side pit reclamation is not possible. The angle of repose of the
blasted overburden is almost 380, which requires a sizable space in the operative sections,
apart from productive platforms, facility recess, and water sink and other utility Space.
As a result, large quantity of blasted wastes are dumped over prime agricultural tracts,
specially purchased for making these waste Dumps. The quantum of problem can be
understood by the figure that 2.5 cum waste has to be stripped off and dumped in the
dump-yards for each metric tonne of Kota Stone production. Capacity of the dump-yards
retaining waste material depends upon many factors such as size, shape, angle of repose
etc, but on an average 1.0 Hq area dump-yard may hold about 1.75 lakh m3 waste
material taking into account angle of repose, optimum square shape and space for haul
roads and benches etc.
The present trend of production level is likely to generate about 138 lakh m 3 of
waste material every year. Presently only 35 percent of this bulk quantity is filled back in
the mined out areas, leaving behind 90.00 lakh m3 waste dumped over prime agricultural
land, requiring 45.0 to 50.0 hectare fresh land for dumping waste generated in a year. As
per our estimates around 1800 lakh m3 waste material is dumped in random formations
covering about 900 to 1000 hectare area.
The third dimension to this problem is of the disposal of the fine slurry released
from the cutting polishing industries. Every year about 2.5 to 3.0 lakh mt of stone polish
is discharged into local convenient places. This affects about 5 to 10 hectares land every
year.
In total both Kota and Jhalawar district are loosing about 120-150 Hectare prime
agriculture land every for facilitating Kota Stone mining, which is quite alarming.
In addition to this one more point needs immediate attention. Kota Stone is a
localized non-renewal natural resource and its limited reserves may not last another
fifteen years with the current policy of liberalized lease sanctioning process and increased
production level. This aspect needs introspection from the point of sustainable growth
and regulation.
The mining in these districts is loosing valuable top - soil at the rate of 8.0 to 8.50
cu.mtrs per year, which is another loss to eco-system.
To overcome the environmental problems as highlighted above, following
measures are recommended.
1. Fresh mining leases should be considered exclusively on the land presently
occupied by the old waste dumps.
2. Mine-owners should be pressed to dumps their waste generations into nearby old
abandoned quarries.
3. The case agreements should have special provisions to force con-current refill after
an initial grace period to facilitate development and space for such refills.
4. Cutting polishing industries should be forced to dump their slurry into old mined
out areas or in the active dumps. Any violation should be penalized.
5
6. 5. Top soil should be mined out separately and conserved for reclamation purposes.
