昌汉沟矿浅埋深薄基岩工作面矿压规律实测研究

Practical Measure Research on Shallow Depth of Burial and Thin Bedrock Coal Face Strata Behavior Regularity of Chang Han Ditch Coal Mine

本文以昌汉沟矿3-1煤上201浅埋深薄基岩工作面为工程背景,通过KBJ-60III型综采支架压力监测系统,监测综采工作支架工作阻力的变化规律,确定了浅埋深薄基岩煤层条件下老顶的周期来压步距,为昌汉沟矿工作面支架选型与安全开采提供了依据。

On the engineering background about Chang Han ditch 3-1 coal seam 201 working face of shallow depth of burial and thin bedrock, by using KBJ-60 type III fully mechanized mining supporter pressure monitoring system, the paper monitors the change rule of mining supporter working re-sistance, determines the main roof weighting step on shallow depth of burial and thin bedrock coal condition and provides the evidence for the selection of supporter and safety mining of Chang Han ditch working face.
