Abstract
Aiming at the problem that the Jurassic coal seam mining in Binchang Mining Area is seriously affected by the water damage of Luohe Formation aquifer, and the overburden failure development law of the fully mechanized mining is not clear. The 204 working face in Tingnan Coal Mine is taken as the research object, using the observation of consumption of flushing liquid, simple hydrological observation, and comprehensive exploration of drilling color TV peeping, the overburden failure development law of coal seam mining in fully mechanized mining face is studied. Combined with the domestic empirical formula for the development of the water-conducting fracture zone of the coal seam roof in the fully mechanized mining face, the method for determining the development height of the overburden failure zone suitable for the fully mechanized mining face in Binchang Mining Area is revised.关键词
