摘要
欢城煤矿32700左翼皮带巷正常开拓时,将要遇到一大型断层,在过该断层时采用了瞬变电磁物探、钻探、水质化验、注浆加固等一些方法,然后顺利通过该断层,求得了安全与效益的双赢。
During the development of 32700 left- wing belt roadway,will encounter a large fault,to pass the fault,the transient electromagnetic geophysical prospecting,drilling exploration,water quality testing,the grouting reinforcement and some other methods were used,and then smoothly passed the fault,both safety and efficiency were obtained.
