摘要
综采工作面矿压显现观测对煤矿安全高效生产具有重要的指导意义。该文通过对梨园河煤矿22111综采工作面在开采过程中顶板及围岩移动规律的观测研究,掌握了22111综采工作面的初次来压和周期来压步距、工作面支架支护强度、围岩破坏活动过程中煤壁应力变化大小和应力影响范围。
Mechanized mining face pressure behavior observation of mine safety and efficient production of important guiding significance. Based on Liyuanhe 22,111 mechanized mining face in coal mining process,roof and wall rock movement law observational studies, mastered 22,111 longwall face initial pressure and periodic weighting step,face bracket supporting strength,rock sabotage the process of changing the size of the coal wall stress and stress influence.
