3. Refers to a group of undeground mining techniques
used to extract coal, oil shale, tar sands, salt and other
minerals or geological materials from sedimentary
(“soft”) rocks.
Mining deposits in sedimentary rocks are commonly
layered and relatively less hard.
Refers to various underground mining techniques used
to excavate hard rocks, mainly those containing metals
such as ore containing gold, silver, iron, copper, zinc,
nickel and lead, but also involves using the same
techniques for excavating ores of gems such as
diamonds.
Mining deposits in hard (sedimentary or igneous or
metamorphic) rocks are commonly massive and hard.
Mining can be done by any one of the following
methods:
1) - Longwall mining;
2) - Room-and-pillar mining;
3) - Blast mining;
4) - Shortwall mining;
5) - Coal Skimming.
Mining can be done by the following methods:
a) - Short-hole and Long-hole mining methods;
b) - Selective and unselective mining methods;
c) - Supported and Unsupported underground mining
methods.

10. SUPPORT SYSTEM CHARACTERISTICS SUMMARY:
- Mixing ratio of 100: 100 parts by mass (1: 1 parts by volume).
- Start of reaction: 2 minutes (± 15 sec); Complete reaction: 6 - 9 minutes.
- Appearance of the expanded product: flexible foam with closed white cell.
- Expansion factor: 5 - 6 times.
- REACTION TEMPERATURE: 50 - 52 ° C
GLOBALFOAM-BT-FLEX:
Is a bicomponent polyurethane resin, injection that produces a low reaction temperature, ideal for use in works where highly
flammable substances are present.

11. ...... With the increase of bank height, larger drilling diameters and higher explosive
power (cost reduction), has involved an increase in the concentration of energy from the
blasting.
If this explosive energy is uncontrolled, it will definitely need a decrease in slope angle,
with greater economic consequences (increased rate of removal) and safety (loose rock
on the bank side, berm berlands planning less safe or would not exist).
The best way for this force not to damage the walls is to control explosive energy
(controlled blasting) .....

13. Underground mines are used to exploit high grade, deep ore bodies. However, there is no limiting
grade above which underground mining is always done, nor is there a limiting depth below which
underground mining is always done. It depends on the mining method used.
For underground mines the mining rate is typically less than 20,000 tonnes per day (tpd); 10,000 tpd
is a large capacity (and highly mechanized) underground mine. However, the block caving method
can achieve mining rates much greater than 20,000 tpd.
Underground mining results in one waste stream: tailings which are the result of a mineral separation
process in the concentrator or processing plant. There is very little waste rock generated as a result
of sinking the shaft or driving the tunnels to gain access to the ore.
Underground mining is generally more selective than open pit mining, but the degree of selectivity
depends on the underground mining method.
The significant design issues of an underground mine are: geometry of underground mining, ground
support, and logistics of materials handling.
Mechanical excavation offers numerous advantages over drill and blast for all types of mine
develompment, including:
- Personnel safety is greatly improved due to elimination of blasting and toxic fumes;
- With machine excavation, ground disturbance is drastically reduced, which results in significantly
lower supoport requirements to provide a safe and stable opening;
- The smooth walls created by machine boring also mean reduce ventilation requirements;
- Unlike drill and blast, machine generates a uniform muck size, which allows for the
implementation of continuous material haulage systems, such as conveyor belts;
- Machine excavation provides a continuous operation, making it highly suitable for remote control
and automation.

formula with low viscosity, does not expand, with high mechanical strength. Ideal for waterproofing broken rocks,
consolidating land and rocks subject to land slide, filling cracks and cavities as well as for constructions, coatings and
insulating materials, for waterproofing the walls of tanks and aqueducts. Non-toxic and non-polluting.FIRE RESISTANT.
- GLOBALSTONE-LV50 (BOLTING SYSTEM FOR TUNNELLING AND MINING):
SEALING AND STRUCTURAL BONDING OF FISSURES AND CRACKS (FLEX) - STRATA CONSOLIDATION –
Organic-mineral two components resin, not expansible, characterized by low viscosity, excellent chimica stability,
