在煤矿井下安全生产过程中,综采工作面由于设备较多,管理难度较大,为了便于回采作业,综采工作面上下顺槽一般不采用转弯设计。但是由于井下地质条件千变万化,有时不得不把工作面两顺槽设计成转弯巷道,这种情况下就需要进行大幅度扇形调采,给综采工作面的安全生产组织协调工作提出更高的要求。
In the coal mine safety production process, fully mechanized mining face due to more equipment, more difficult to manage, in order to facilitate mining operations, fully mechanized mining face down the groove generally do not use turn design. However, due to the ever-changing underground geological conditions, sometimes it is necessary to design two working troughs as turning roadways. In this case, it is necessary to carry out large-scale fan-shaped mining to place higher demands on the organization and coordination of work safety in fully mechanized coal mining face .
