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

摘要：

Huaibei Mining Area is located in the south of the North China Coal-bearing Region. Its hydrogeological condit(i)on 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 different features of water inrush caused by different geological structure condition and water-inrush passage, which is of typical meaning to study controlling of rock mass structure on water inrush from coal seam floor.
