This document discusses group members for a project on mine waste management. It then provides information on different types of mine waste, effects of mine waste, and methods for managing and reusing mine waste. Management of mine waste is an important part of modern mining, as plans are required for mine closure and site cleanup. While waste disposal remains a challenge, efforts are being made to understand waste impacts and support more environmentally conscious mining.

5. Introduction Mining Waste
 Mining operation brings out all sorts of
unwanted materials, which is known as mining
waste.
 Mining waste can be defined as a part of the
materials that result from exploration, mining
and processing of substance governed by
legislation on mines and quarries.
 Mining operation also produce diverse kind of
potentially hazardous waste.

6. MINING EXPLORATION

7. Mine Exploration
 Mine exploration is a sequential process of
information gathering that assesses the
mine potential of a given area. It starts with
an idea or geologic model that identifies
lands worthy of further exploration.

8. The Mine and Quarries Act 1954
 The Royal commission on safety in coal mines (1935 to 1938) was
set up “ to inquire whether the safety and health of mine workers
can be better assured by extending or modifying the principles of
the general provisions of the Coal Mines Act, 1911”.
 The Second World War ( 1939 to 45) and the Nationalization of
the coal industry in 1947 delayed enactment until November 1954
and its provisions did not come into effect until 1 January 1957.
The 1954 Act dealt with general principles with detailed technical
requirements covered by Regulations.
 In the period from 1957 to 87 nearly fifty sets of detailed
Regulations and Orders were made to keep developing
technology.

9. These are the methods techniques employed when the
depth of the deposit, the stripping ratio of the overburden
ore, pr both becomes excessive to surface exploitation.
Terminology
Mining:
The activity, occupation and industry concerned with
the extraction of minerals.
Underground Mining:
Mineral exploitation in which all the extraction is
carried out beneath the surface of earth.
Underground Mining Methods:

10. Types of Mine Waste
There are different types of mine waste materials which vary in their
physical and chemical composition, their potential for environmental
contamination, and how they are managed at mine sites. types of mine
waste include:
Tailings:
Are finely ground rock and mineral waste products of mineral
processing operations. Tailings can also contain leftover processing
chemicals, and are usually deposited on the form of a water-based slurry
into tailings ponds (sedimentation lagoons enclosed by dams built to
capture and store the tailings), although offshore tailings disposal has
been successful in some cases.

11. TAILING

12. SLAGS
Are non-metallic by products from metal smelting, and were
historically considered to be waste. Slags are largely environmentally benign,
and are being used increasingly as aggregate in concrete and road
Construction

13. Is produced in a number of ways at mine sites, and can vary in its
quality and potential for environmental contamination. Water at mine sites
is frequently monitored and various water management strategies have
been developed to reduce the amount of mine water produced, and treat
the water before it is discharged to environment.
Mine water:

14. Effects of Mine Waste
Mine wastes may be in the form of Solid waste, Water waste,
or Gaseous waste.
 Harmful environmental effects of Mine:
• Subsides ( subsurface mining hazard).
• Toxic- laced mining waste.
• Acid mine drainage.
• Air pollution.
• Major pollution of water and air.
• Effect on Aquatic life.
• Large amounts of solid waste.
• EPA cites that mining has polluted 40% of western watersheds.
 Illegal Mining:
Water poisoning of all the living things in it. Destruction of
beautiful coral reefs. Barrenness of and.
• Disruption of and surface

15. Major pollution of water
 Acid mine drainage
 Leaching of heavy metals
 Oil and chemicals spills
 Highly toxic cyanide salts are used to extract gold from its
ore; leave behind cyanide laden water.
 The major environmental impacts from waste disposal at
mine sites can be divided into two categories;
 loss of production land following its conversion to a waste
storage area and the introduction of sediment, acidity and
others contaminates into surrounding surface and ground
water from water running area exposed problematic or
chemically reactive wastes.

16. Turning Mine wastes into a resources
The large volumes of waste produced at mining operations are expensive to
manage, and are frequently cited as an obstacle in the environmental sustainability of
mining. The mining industry plays a leading role in waste management, and is one of few
industries that recycles its own waste. Uses of mine waste include:
1- Waste rock:
Can be reprocessed to extract minerals and metals, used as back fill, land scaping
material, aggregate in road construction, or feedstock for cement and concrete
2- Manganese tailings:
Have been used in agro-forestry, building and construction materials, coating, resin,
glass, and glazes.
3- Clay-rich tailings:
Have been used for making bricks, floor tiles, and cement.
4- Slag:
Is often used for road construction, and in concrete and cement.

17. Turning Mine wastes into a resources
5-Red mud:
Bauxite red mud is solid alkaline waste produced in aluminum refineries.
Red mud has been used as a soil amender, in waste water treatment, and as raw
material for glass, ceramics, and bricks.
6-Water treatment sludge:
Sludge from ARD treatment, which is high in iron, has been sold
commercially for use in pigments.
7-Mine water:
Is used for dust suppression and mineral processing, industrial and
agriculture uses, as a coolant, and as a source of drinking water .
8-Sulphur oxide emissions:
Many smelters have installed acid plants to convert sulphur dioxide to
sulphuric acid, a useful industrial chemical.

18. Method of management has been described as getting thing done by other
people. They are responsible for planning organizing and controlling
organizational activities manager set budgets monitor those budgets and
identify way making sure that budget as well as people managers resources
people, plant, time, material finance etc. People sometime think management is
very precise science.
Represent the specific mean of management . It manage the organization,
resources and its processes manage . The significantly affect the planning,
organizing and the performance of other managed function. The despite the
recycling and reuse of many wastes at time mine sites the majority of waste
produce is still place into storage facilities. The reclamation and long time
management of those facilities has been become a important part of modern
mine development and mine closure. The plans for mine closure and site
cleanup are required as part of the mine permitting process is caned and the
plans are uploaded after additional study.
Management of Mine waste

19. Conclusion
1- Safe disposal of mine waste.
2- Humans must focus in understanding the character, stability,
impact, remediation and reuse of the mine waste.
3- Currently, extensive planning for and caring out
environmentally conscious mining activities of sites cleanup and
rehabilitation of mine waste are of primary concern.
