Practice and cognition of fully-mechanized mining under reservoir of Daping Colliery in recent decades

摘要：

　　The success of mining test under water-bodies lasting from April 2005 to July 2015was achieved by Daping Colliery.42.15 million tons of coal and 5 billion yuan of corporate profits were obtained in panels of N1S1,S2S2, S2N1, N1 S2, S2S and N1S3.In the process of pilot production, centering on the comprehensive security technology of fully-mechanized mining under water-bodies, the research was carried out from the view of strata damage, mine hydrology, the surface crack growth, water on-line automatic monitoring system and fault activation,
