水力压裂技术在煤矿瓦斯治理中的应用

Application of hydraulic fracturing technology in gas control of coal mine

煤矿开采条件十分恶劣,在井下作业时井下瓦斯浓度较高,加上开采时煤层因透气性影响在透气性无法达到理想效果时便会使瓦斯含量增大,影响煤矿开采的安全性。随着煤层深度的增大瓦斯的含量也会越来越高,从而为提升煤矿开采的危险性。为保证煤矿开采的安全和稳定,降低煤矿开采风险度,有必要对水力压裂技术进行研究[1]。

The mining conditions are harsh,especially in the underground operation while the gas concentration in the underground is high.In addition,the coal seam increases the gas content when the gas permeability cannot achieve the desired effect due to the permeability of the coal seam during mining,which affects the safety of coal mining.As the depth of the coal seam increases,the gas content also becomes increasingly high,thus increasing the risk of coal mining.In order to ensure the safety and stability of coal mining and reduce the risk of coal mining,it is necessary to study the hydraulic fracturing technology.
