倾斜短壁式水采工作面的矿山压力显现规律

The Law of strata behaviours in Hydraulic Shortwalling A- long the Dip

本文通过分析水采和旱采顶板运动的特点 ,采用有限元及力学的方法研究了水采工作面沿倾向与走向的顶板运动规律。结合现场观测的结果 ,指出了水采工作面的矿山压力分布及其显现规律 ,得出了水采冲击地压发生的机理。

Investigation into the law of movement of roof stratum at the face,when a shortwalling system to the dip or along the strike of applied,is made with finite element and me- chanical methods.Based on the actually-measured data,the distribution and law of manifestation of rock presure as well as the mechanism of occurrence of pressure bump in hy- dromine have been brought to light.
