摘要
针对煤矸石地层松散破碎易塌孔的特点,通过改进传统袖阀管注浆工艺,介绍了一种适用于煤矸石地层的注浆工艺,并且应用于工程实践中,取得了良好的效果,具有一定的推广意义。
According to the characteristics of loose and fragile coal gangue stratum, a new grouting technology suitable for coal gangue stratum is introduced by improving the traditional sleeve valve tube grouting technology, which has achieved good results in engineering practice and has certain popularization significance.
