厚煤层综放工作面过断层技术实践

Practice of Fault Crossing Technology in Fully Mechanized Caving Face of Thick Coal Seam

断层是岩层或岩体顺破裂面发生明显位移的构造,断层在地壳中广泛发育,是地壳的最重要构造之一,对煤矿正常生产造成一定的影响,井下从事采掘过程中遇到较大断层如何安全快速通过是急需解决的难题,因此针对西曲矿18502工作面遇断层所采用的方法,与目前国内现有的几种破裂岩石的一些方法进行了对比,在理论基础上探寻适合解决采掘工作面过断层、无炭柱等地质构造的方案。

Faults are the structures with obvious displacement along the fracture surface of rock strata or rock mass.Faults are widely developed in the crust,and they are one of the most important structures in the crust.They have a certain impact on the normal production of coal mines.How to pass large faults safely and quickly in the process of underground mining is a difficult problem to be solved urgently.Therefore,the methods adopted for faults in 18502 working face of Xiqu mine are discussed.Comparing with the existing methods of fractured rocks in China,this paper explores a suitable scheme to solve the geological structure of mining face such as crossing faults and carbon-free pillars on the basis of theory.
