瓦斯抽放钻孔封孔工艺优化探讨

Discussion on the Optimization of Sealing Technology for Gas Drainage Drilling

A煤矿原来采用的封孔处理工艺存在很多问题,无法准确地对注入的水泥浆量进行控制,也不能对封孔剂进行定位,解决不了在不同倾斜角度下的封孔漏气问题,需要对原封孔工艺进行优化。从现场实际应用效果来看,新封孔处理工艺可以有效提升封孔处理效果。

There are many problems in the original sealing process used in A Coal Mine,which can not accurately control the amount of cement slurry injected,and can not locate the sealing agent,and can not solve the problem of air leakage under different inclined angles.Therefore,it is necessary to optimize the original sealing process.From the practical application effect,the new sealing technology can effectively improve the sealing effect.
