大采高放顶煤工作面矿压显现规律及围岩控制研究

The Laws of Strata Behavior on the High Seam Top Coal Working Face

通过对大采高放顶煤工作面进行矿压规律实测,研究大采高综放条件下上覆岩层结构及运动特征,掌握工作面的初次来压、周期来压规律,探讨支架-围岩关系及优化液压支架选型。本文以理论分析为基础,并以某矿一号井大采高综放面为例,总结了大采高综放面矿压显现规律。

It is of significance to observe the laws of strata behavior on th high seam top coal working face for studying the structure of overburden, grasping the laws of first pressure and poop pressure, the relating support and surrounding rock and choosing the support type. This paper gives the laws of strata behavior on the high seam top coal working face theoretically,taking the first mine in a coal mining corporation as an example.
