摘要
林西矿为深部开采矿井,其综采工作面经常遇到构造断层,特别是比较大的断层,严重影响工作面的正常推采进尺。以该矿1021综采工作面为例,分析该工作面大落差逆断层情况,确定过断层的方案,并介绍了在过断层过程中采取的一系列技术措施。实践表明,该方案实施效果良好,为在复杂地质条件下综采工作面过大断层提供了借鉴经验。
Linxi Mine with large mining depth and commonly tectonical fault,especially with large fault,severely affecting the normal mining.1021 fully mechanized working face of Linxi Mine was taken as example,the technical measures of reverse fault with large fall mining were introduced.The practice showed that the technology,with good implementation effect,provided reference for fully mechanized working face crossing large fault under complex geological condition.
