mining sector, from 1984 to 2009 amounted to some US$10 billion. Small-scale mining of precious minerals continues to make significant contributions to the country's foreign exchange earnings. For example, total gold production by small scale miners had risen from 2.2% in 1989 to 18% of the national production in 2009.
Limestone is also used as a scrubber stone in the desulfurization of flue gas and is used as a reagent in blast furnaces to extract iron from ore. Because of the wide variety of uses for limestone, quality control and precise characterization is an important part of limestone mining and processing operations.

Respirable coal mine dust is a hazard in underground and surface coal mines and in coal-processing facilities. It is a mixed dust, consisting mostly of coal, but can also include silica, clay, limestone and other mineral dusts. The composition of coal mine dust varies with the coal seam, the composition of the surrounding strata and mining methods.

The objective of ground control is to use site information and the principles of rock mechanics to engineer mine structures for designed purposes. Massive failures of pillars in underground mines, severe coal and rock bursts, open-pit slope failures, and roof and side falls all represent unexpected failures of the system to meet its design ...
The dynamic mechanical properties of limestone are studied with 5 types of impact pressure acting on limestone samples in axial direction in this paper. The rubber shaper with a diameter of 5 mm and thickness of 2 mm is adopted. Besides the conical punch of split pressure bar of Hopkinson with a diameter of 50 mm is also used.

Limestone in powdered form is also used as a substance to absorb pollutants or control coal mine dust at many coal-mining facilities. Lime which is the byproduct of limestone is used to neutralize acids and treat wastewater, industrial sludge, animal waste, and water supplies. These are some popular uses of limestone.

Similarly, taking the gas desorption of L1–L3 limestone as an example, according to Table 1, the distance between No. 8 coal and L1 limestone is 0, and the farthest L3 limestone is only 2.36 m and its gas content and pressure first affect L1– L3 limestone. Therefore, if L1– L3 limestone gas has a significant impact on mining, it is a ...

Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more ...

Limestone or calcium carbonate (CaCO 3) exists as a natural stone throughout the world. Limestone in its natural form is very slow reacting; therefore, it has a limited use. The most significant use of pulverized limestone is in agriculture in a finely ground and dry form or in flue gas desulphurization in slurry form. The use of lime in carbonate
