针对急倾斜煤层综采工作面飞煤矸对人员、设备的安全威胁,对生产效率的制约问题,通过俯伪斜开采方式、增设改进液压支架防飞煤矸装置,从源头减少飞煤矸量的同时,有效避免了煤壁侧、支架尾部、支架行人通道等各个方向产生的飞煤矸下滑对人员及设备造成的安全威胁。提高了安全系数,减少了生产影响,取得了较好的经济和社会效益。
Aiming at the safety threats of coal gangue to personnel and equipment in the fully mechanized mining face with steep coal seam and the restriction on the production efficiency, the coal gangue prevention and control device is added to improve the anti-fly ash gangue device of hydraulic support by reducing the pseudo-inclined mining method, At the same time, the safety threats to personnel and equipment caused by the decline of flying coal gangue generated in various directions such as the coal wall side, the tail of the supporter and the support pedestrian passage are effectively avoided. Improve the safety factor, reduce the production impact, and achieve good economic and social benefits.
