Title: Treatment Technology of Fault Fracture Zone in 8707 Full-mechanized Mining Face of Jinhuagong Colliery
Abstract: Serious coal-wall slide,roof fall occurred during 8707 full-mechanized mining face advanced in fault fracture zone which resulted into powered supports movement difficulty and seriously influenced safety mining. On the basis of analyzing characteristic of coalwall sliding and roof fall in mining face,comprehensive treatment measures were put forward which included formulating mining technique for fault range,applying marithan material to reinforcing broken roof,strengthening maintenance and management of powered support. With the measures,coal-wall sliding and roof fall was successfully controlled and mining face smoothly mined through fault broken area. This comprehensive treatment technology not only provided important technical supporting for safe mining,but also present some experience and reference for similar mine.
