摘要
为了揭示孤岛短壁煤柱工作面矿压显现规律,以王庄煤矿43M1煤柱工作面为例,采用理论分析、数值模拟与现场实测相结合的方法,研究了工作面的来压特征、顶板破断形式、侧向及超前支承压力分布规律,运用数值模拟软件分析了"孤岛"、"短壁"2个因素在矿山压力显现中的影响;现场实测与理论分析及数值模拟结果相吻合。
In order to reveal the strata behavior laws of isolated short wall coal pillar fully mechanized caving face, taking 43M1 coal pillar working face in Wangzhuang Coal Mine as an example, based on theoretic analysis and numerical simulation and field measure- ment, this paper discusses weighting features and the form of roof breaking form and two sides abutment pressure and the advance abut- ment pressure. The influence of two factors including ＂isolated＂ and ＂short wall＂ on strata behavior laws was analyzed with numerical simulation software. The field measurement results are well agreed with theoretical calculation and numerical simulation.
