COAL MINING AND THE ENVIRONMENT

2016-2-4 · Abstract The environmental impacts of coal mining in South Africa are reviewed. The primary impacts arise from mining, particularly underground mining, largely because South African coal mines are relatively shallow. Coal washing gives rises to large waste dumps, which may ignite spontaneously and cause air pollution.

Coal mining impacts on catchment runoff

Coal mining could cause drastic drop of groundwater level, obvious decrease of river base flow and total runoff in dry season. In addition, the subsidence of coal mine goaf, and water-conducting fissures also could cause the loss of surface water.

Coal mining cost model. Volume 1. Underground coal

2021-6-4 · Abstract. The revised EPRI coal mining cost models represent a computerized approach to the analysis of production costs and mining requirements of either surface or underground mining projects. The models estimate all capital and operating costs typically associated with the preproduction and production phases of a coal mining project, and may be

Advances in Coal Mine Ground Control ScienceDirect

Abstract. Thick coal seam is the main coal seam to achieve high efficiency coal mining. In this chapter, the common mining methods for thick coal seams are introduced. There is a large-cutting-height mining method and a top-coal caving mining method. Also, the ground control for the thick coal seam mining is described in this chapter.

The influence of subsidence attributable to coal

Abstract. Coal mining has been practised in some parts of the world, notably western Europe, for centuries and this type of mining has evolved over time as mines became deeper and larger. Today coal is worked primarily by room-and-pillar, and by longwall methods. One of the consequences of mining is subsidence, and it is associated with past
