摘要
断层是影响采煤工作面实现正常回采的一个重要因素。为解决1152综放工作面所遇落差为3.6m正断层的快速过断层问题,经深入研究分析,在该工作面运输巷预掘爆破巷,然后对巷道两帮坚硬岩石进行打眼、松动爆破,提前对影响工作面推进范围内的岩石进行处理。现场实践表明,消除了坚硬底板岩石对工作面正常推进的影响,实现了综放工作面快速过断层。
Fault is regarded as an important factor affecting the coal face to achieve a normal stoping.In order to resolve the 1152 face with a 3.6m normal fault,pre-excavation blasting roadway through the face transport is recommended from in-depth research,followed by drilling hard rock,loose blasting on the roadway,where the rock that affects the advancing is processed in advance to eliminate the effect of the hard rock in bottom,and a rapid passing through fault is finally realized.
