Study on Scientific Exploitation Technology for Coal-and-gas Double-energy in High Gassy Coal Seam Group

摘要：

By using the method of theoretical analysis, numerical simulation and practical experiment, the distribution character of mining fissure and law of gas moving in gob are studied. The combined suction way by long and large diameter roof fissure borehole group and high-position borehole group is brought forward and the scientific exploitation technology system for coal-and-gas double-energy established. The practical experiment proves the high concentration gas can be drained out effectively by reasonably laying out the boreholes position. The effect of gas controlling is good, and finally the scientific exploitation for coal-and-gas doubleenergy can be achieved in Shaqu colliery.
