Abstract:

Abstract: Against the bad condition of roof and smaller angle for C2401 coal face of Cheng Jiao coal mine, new technology of the gob-side entry retaining and the bag-type filling mining with super high-water material in fully mechanized mining coal face is proposed by studying the basic properties of super high-water material. Applied bolt-beam-mesh support technology in the transportation inclined roadway within bag-type filling mining with super high-water material in fully mechanized mining coal face. The results showed that the bag-type filling mining with super high-water material cooperated with bolt-beam-mesh support technology, which is appropriated for the gob-side entry retaining and the bag-type filling mining in fully-mechanized mining coal face in a wet, cold and closed environment, direct effect and high mechanization, which is an advanced green filling mining method under buildings.

Key words: Keywords: fully-mechanized mining, superhigh-water material, bag-type filling, gob-side entry retaining
