摘要：
In order to solve technical problems which restricted coal mining operation, such as low penetrability of coal mass and low efficiency of gas extraction, according to geological mining condition of Yuyang Mine, Crossing Borehole Hydraulic Fracturing system was designed and investigated in N3704 west gas tunnel (below). The system was based on coal or rock mass hydraulic fracturing theory and gas flow theory. Through the experimental study of fracture and analysis of fracturing effect after inspection, the result of field test shows that Crossing Borehole Hydraulic Fracturing system could improve the gas extraction efficiency significantly. The test result provides a basis for hydraulic fracturing operation in other mines.
