The karst collapse pillar (KCP) is a common geological structure in the coal mines of northern China. KCPs contain many fractured coal rocks, which can easily migrate under the action of high-pressure water. The destruction or instability of the cementation structure between the rocks can directly induce coalmine water-inrush accidents. To study the seepage stability of cemented and fractured ...
Contour mining is commonly practiced where a coal seam outcrops in rolling or hilly terrain. Basically, the method consists of removing the overburden above the coal seam and then, starting at the outcrop and proceeding along the hillside, creating a bench around the hill.
Coal mining and processing The conventional open-pit mining method involving, drill, blast, load and haul operations are employed at the Chernogorsky coal mine. The extracted coal is sent to the nearby Chernogorsky coal washing plant for reducing the ash content and for improving the coal value. The washing plant was commissioned in 2013.
