综采过断技术在东周窑矿的应用

Application of the Fully Mechanized Mining Breaking Fault Technology in the Dongzhouyao Mine

综采在推进过程中经常遇到断层,采用小搬家的方法,既费时间又浪费资源。采用综采过断,正确选用炮眼参数、装药量进行震动破岩,改变岩层结构、降低强度,从而使得综采顺利通过断层,既节约了断层两侧的煤,又节省了大量的搬家时间。

Fully mechanized mining always encounters faults during propulsion,and the use of small-moving approach wastes both time and resources. By correctly selecting the borehole parameter and the amount of powder, the fully mechanized mining breaking fault technology will blast the rock, change its structure and decrease its intensity,which makes sure the fully mechanized mining get across the fault. This method not only saves the coal resource on both side of the fault,but saves time for moving.
