以渝阳煤矿N3704西瓦斯巷压裂目标区地层参数，建立不同注水孔径下的泵注压力与影响半径的关系模型。模拟结果表明：压裂注水钻孔直径分别为φ113 mm 、92 mm 、75 mm 时，压裂注水载荷为40.0、44.5、51.0 M Pa ，两孔之间可形成裂隙贯通；在相同孔径压裂情况下，压裂半径随压力增加而增加；随着钻孔直径的增加，导致裂隙贯通所需要的注水压力呈递减趋势。

Using coal mine of Yuyang N3704 fracturing zone of the west gas formation parameters ,the relational model of pumping pressure of different water injection with influencing radius under the ap-erture is established. Simulating results show that ,when the hole diameter of fracturing water injec-tion is φ 113 ,92 ,75 mm respectively ,the fracturing load of water injection is 40 ,44.5 ,51 MPa ,and fracture penetration can be formed between the two holes. In the condition of the same aperture frac-turing ,fracturing radius increases with the increase of pressure. With the increase of hole diameter ,a degressive trend of water injection pressure that fracture through needs is resulted in.
