煤柱工作面矿压显现规律分析

通过对寺河矿煤柱工作面矿压观测分析,得出煤柱放顶煤工作面的矿压显现特征,综合评价了其支架的适应性与工作状态,认为目前使用的支架能够满足生产需要,同时由于工序对矿压影响不大,生产中可认为支架处于正常工作状态。该研究对同类条件下煤柱放顶煤工作面开采具有指导意义。

Study on Strata Behavior Regularty in Pillar Face

Based on the observation and analysis of strata behavior in the pillar Sihe Coal Mine,the characteristics of strata behavior in the pillar caving face was obtained.This paper gives a comprehensive evaluation on the adaptability and work state of its support,and it deems that the support now used can meet the need of production.Since the working procedure has not great influence on the strata behavior,the support can be regarded as in the normal work condition.This study has instructional significance for the pillar caving face with similar conditions.
