综采工作面大角度扇形开采工艺

摘要

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回转开采，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 process of the coal mine safe production,due to the fully mechanized coal face equipment is more, management is difficult,for the purposes of mining operations,up and down along the trough is generally not turning design in fully mechanized working face.But due to the underground geological conditions,sometimes have to face two consecutive roadways,designed to turn this kind of circumstance is the need for large fan-shaped rotary drilling,for fully mechanized working face production safety organization and coordination work put forward higher requirements.
