乌东煤矿45^#急倾斜煤层采空区与水患探测分析

Detection and analysis of goaf and flood in Wudong coal mine with 45# steep coal seam

神新公司乌东煤矿急倾斜特厚煤层已进入深部开采水平。历史性无序开采形成的采空区分布的不规则性与水患严重影响深部安全开采。以乌东煤矿+600水平东冀45#急倾斜煤层工作面附近历史性采空区与水患探测为目标。通过现场调查,基于雷达探测,分析了采空区与水患情况,为现场安全开采提供科学依据。

Wudong coal mine with inclined and thick coal seam is in the mining state of deep level. The irregular distribution of goaf caused by historically disordered mining and flood seriously affected the safety mining at deep level. For the target of historic goaf and flood detection at ＋ 600 level East 45^# coal seam in Wudong coal mine, the goaf and the flood situation were analysed through field investiga- tion and geology radar detection, which provided scientific basis for the safety mining.
