羊东矿8472工作面区域治理与分析

Regional control and analysis of No.8472 face in Yangdong Mine

峰峰集团羊东矿水文地质条件复杂,目前开采的2号煤及4号煤工作面全部受底板奥灰威胁。采用地面区域超前注浆加固治理技术对4号煤层下伏大青灰岩含水层进行探查及注浆加固,来实现2号煤及4号煤的安全带压开采是本文研究的重点。本文通过对羊东矿8472工作面区域治理的全过程进行论述和分析,为今后相邻工作面的治理工作提供技术借鉴。

The hydrogeological conditions of Yangdong Mine of Fengfeng Group are complex.At present,the No.2 coal and No.4 coal working faces are all threatened by the floor Ordovician limestone.It was the focus of this paper to explore and grout the Daqing limestone aquifer under No.4 coal seam by using the advanced grouting reinforcement technology in the ground area to realize the safe mining of No.2 coal and No.4 coal.This paper discussed and analyzed the whole process of regional control of No.8472 face in Yangdong Mine,and provided technical reference for the control of adjacent working face in the future.
