摘要
以寺河矿4303大采高长工作面末采阶段过大断层为背景,结合现场实际情况,通过对不同过断层方案的对比分析,确定了采用挑顶破岩强行过断层的技术方案,并对方案的关键技术及参数进行了研究,同时提出了过断层期间的施工管理措施及注意事项,减小了过断层施工对工作面正常回采造成的影响。
4303 long working face of Sihe Coal Mine is passing through large fault during the period of end-mining, and the mining height of this working face is very large. Taking this as background, based on the actual situation, according to the comparison analysis about different schemes of passing through fault, the technology scheme of breaking top rock to pass through fault was finally deter- mined, key technology and parameters of the scheme were also analyzed carefully, at the same time, management measures and attentions should be taken to during passing through the fault were put forward, the application of these methods reduced the serious effect of pass- ing through fault on working face.
