摘要
凤凰山煤矿XV4308综采工作面采用沿空留巷的工艺,为保障工作面生产期间沿空留巷的安全性,在工作面回采期间进行了矿压观测,对收集的数据进行了分析,得出了坚硬顶板条件下沿空留巷及工作面矿压显现规律,并通过观测数据分析了液压支架和充填墙体的应用效果。
Using the gob-side entry retaining technology of XV4308 fully mechanized coal mining face in fenghuangshan coal mine, during mining, to ensure the safety of working face, and provide reference for the similar conditions, by analyzed the mine pressure observation data, gotten the mine pressure behavior of working face and entry under the condition of hard roof, and analyzed the effect of hydraulic support and filling wall by observation data.
