晋华宫矿8707综采工作面在推进到断层破碎带附近时出现了严重的片帮、冒顶现象,致使支架难以向前推移,给工作面的安全生产带来了极大影响。在对工作面的片帮冒顶特征分析的基础上,针对出现的问题提出了综合治理技术措施:制定综采工作面过断层工艺、应用马丽散材料注浆加固破碎顶板、加强支架的维护和管理,最终成功地控制了工作面的片帮冒顶,顺利通过了断层破碎带。这种综合治理技术,不仅为实现晋华宫矿的安全开采提供了重要的技术支撑,也为类似矿井的顺利开采提供了相应的经验和参考。
晉華宮礦8707綜採工作麵在推進到斷層破碎帶附近時齣現瞭嚴重的片幫、冒頂現象,緻使支架難以嚮前推移,給工作麵的安全生產帶來瞭極大影響。在對工作麵的片幫冒頂特徵分析的基礎上,針對齣現的問題提齣瞭綜閤治理技術措施:製定綜採工作麵過斷層工藝、應用馬麗散材料註漿加固破碎頂闆、加彊支架的維護和管理,最終成功地控製瞭工作麵的片幫冒頂,順利通過瞭斷層破碎帶。這種綜閤治理技術,不僅為實現晉華宮礦的安全開採提供瞭重要的技術支撐,也為類似礦井的順利開採提供瞭相應的經驗和參攷。

Serious coal-wall slide, roof fall occurred during 8707 full-mechanized mining face advanced in fault fracture zone which re-sulted into powered supports movement difficulty and seriously influenced safety mining.On the basis of analyzing characteristic of coal-wall sliding and roof fall in mining face, comprehensive treatment measures were put forward which included formulating mining tech-nique 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.
