长期以来煤矿瓦斯灾害一直是制约煤矿安全、高效生产的重要因素。随着矿井开采深度的增加，瓦斯超限现象时有发生，给矿井生产带来了安全隐患。对于透气性系数低，抽放困难的煤层，管理上很难实现“掘、抽、采”的平衡。为此，王行庄煤矿引进了定向水力压裂增透技术，并成功的进行了现场试验；试验结果显示，水力压裂后，瓦斯抽放量大幅度上升，水力压裂增透效果良好。

Coal mine gas disaster has been an important factor that restricted coal enterprises secure and efficient production within a long time. With underground mining depth increases, the gas gauge phenomena have occurred, and it brings the hidden danger to mine safety production. To coal seam that permeability coefficient is lower and gas drainage is difficult, it is very difficult to achieve the balance of digging, pumping and mining in the aspect of management. Therefore, directional hydraulic fracturing increased permeability technology was recommend to Wangxingzhuang coal mine, and the field experiment was conducted suc- cessfully ; the test result shows that the quantity of gas drainage increases substantially after hydraulic fracture and the effect of hydraulic fracturing increased permeability is very good.
