摘要
大明煤矿地质条件复杂,在送ES702刨煤工作面时碰到断层带。为躲避断层带及最大限度地回收煤炭资源,将工作面设计为不等长工作面,工作面与回风平巷成57°,需要在机尾进行掐板、回撤支架,保证工作面推进顺利进行,这是一种新的回采方法。
The geological conditions are complex in Darning Coal Mine. The faults are encountered in sending ES702 slicer face. In order to avoid the faults and mostly recover coal sources, the face is designed the unequal face with the back wind drift into 57°. It＇s necessary to pinch the tail board of scraper conveyer and to retrace hydraulic supports, in order to ensure the smooth progress of face. This is a new mining method.
