摘要
通过对凌志达煤矿15101工作面支架工作阻力监测与分析,研究了首采工作面矿压显现规律。结合现场实测与数值模拟手段,对综采工作面回采并巷道变形情况、工作面上下顺槽支承应力分布规律进行了系统的分析研究。结果表明,该工作面矿压显现不剧烈,工作面选用的支架较为合理;同时指出了开采过程中存在的问题,为该工作面的高效安全生产及接替工作面的布置提供了理论和现实依据。
Based on support which belong to Ling Zhida coal mine 15101 working surface working resistance monitor and analysis,the mine pressure behave law of the first coalface is studied,combined with on-site real-time detection and numerical modeling tools,carried out a systematic analysis for distortion of the mining gateway and law of stress distribution of roadway supporting in coal face in fully-mechanized face.Results indicate that strata behaviors of this working surface is not dramatic,selection of support in work surface is more reasonable,Meanwhile,the problems in the mining process is pointed out,which provide the theory and the reality basis for the working surface highly effective safety in production and the arrangement of replace face.
