Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the ...

General open pit/quarry inspection. This app was created for small mines, quarries and other extractive industries to help identify workplace hazards in order to prevent accidents and injuries. Using a checklist helps provide a consistent workplace inspection process and documentation that proper protocol is being followed at all times.
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

open pit mining operations along with several alternatives to assess the validity of its results. As a result, three metrics are proposed to evaluate the performance of the emissions control programs implemented in open pit mines. The methodology was applied to 7 of the 8 open pit coal mining companies operating in Colombia. A description of
DUST CONTROL PRACTICES IN INDIAN COAL MINES Dust control involves either dust consolidation or dust capture. Dust consolidation is normally practiced for settled dust which becomes airborne in favourable condition haul roads of open cast mines. Dust collection or capture is resorted to when it is airborne.
