减小地应力对煤矿开采影响的方法

Method for Reducing Influence of Geo-stress on Coal Mining

  • 摘要: 为减小地应力对煤矿开采影响,以大安山煤矿为研究对象,通过现场地质调查、对采煤工作面及巷道的矿压观测结果分析,提出以下方法:合理划分采区;合理安排开采顺序;采用无煤柱护巷;加快采煤工作面的推进速度;选择合理的回采巷道支护形式等。自实施以来,效果较好,保证了煤矿的安全开采。

     

    Abstract: In order to reducing the influence of geo-stress on coal mining,several methods were put forward on the basis of geological investigation and the analysis of observation result of underground pressure in mining-face and roadway.They were: rationally designing mining zones and mining sequence,designing roadway without coal pillar,increasing mining speed and selecting rational roadway supporting manner.Application effect was good and safety mining was realized.
