铁新煤矿E902工作面过断层方案研究

Study on Tiexin Coal Mine E902 Working Face Crossing Fault Scheme

铁新煤矿9#煤层为薄煤层,正在回采的E902工作面前方有一落差3m的大断层,严重影响综采工作面正常回采,为此提出了工作面直接过断层和补掘巷道避让断层两种技术方案。为确定合理的方案,分别从出矸量、工程量、工程费用、资源回收率及安全性等方面进行了研究,通过研究发现当采取工作面直接过断层时比较合理,在经济、技术、安全方面都是可行的。

The nineth coal seam of Tiexin coal mine is thin coal seam with large fault,three meters fault -line is in front of the working face E902,seriously affecting the normal mining in fully mechanized working face,so set up two schemes for the face and roadway crossing fault and avoiding fault.In order to determine the reasonable plan, respectively from the waste rock,engineering quantity ,cost,resource recovery and safety and other aspects of study, through the study found that when using the work face crossing fault is reasonable and feasible both in economy, technology,security.
