淮北矿区煤层底板突水的岩体结构控制研究

淮北矿区位于华北聚煤区南部,其水文工程地质环境具有华北煤田的基本特征,水文地质条件复杂,山西组煤层开采普遍受到底板灰岩水的严重威胁,曾发生多次底板突水事故。本文介绍了淮北矿区煤系水文地质与工程地质特征,并对研究区底板突水典型案例进行了系统分析,揭示了不同的底板地质构造条件和突水通道所导致的突水特征的差异性,对于认识底板突水的岩体结构控制具有典型意义。

Reseach on Controlling of Rock Mass Structure on Water Inrush From Coal Seam Floor in Huaibei Mining Area

Huaibei Mining Area is located in the south of the North China Coal-bearing Region.Its hydrogeological condition has basic features of the North China Coalfield.The hydrogeological condition is complex.The mining in the coal seam of Shanxi Formation where water inrush from coal seam floor happened mang times is generally seriously threatened by the limestone water from floor.The paper systematically analyzes typical cases about water inrush from coal seam floor in the researched area,and uncovered the diffe...
