煤矿破碎围岩注浆加固技术研究现状分析

Rnalysison study Status of Coal Mine Fractured Surrounding Rock Grouting Reinforcement Technique

基于当前注浆技术在煤矿破碎围岩加固中得到广泛应用的实际情况。从注浆材料、注浆理论及工艺、注浆评价体系等角度探讨了注浆技术研究现状。指出了当前注浆技术中存在理论研究滞后,注浆材料本身弊端较多,注浆设备研发不足,注浆加固评价体系空缺等诸多问题,并基于此提出了注浆技术的发展方向。

Based on the actual situation that grouting reiniorcement technique is widely apphed m coal mine fractured surrounding rock, the research status of grouting technique is studied from the view of grouting material and theory, engineering technology and e- valuation system. The problems of lagging theory study, grouting material existing lots of disadvantages, insufficient grouting equipment study, vacant grouting evaluation system existing and so on, have been pointed out in modern grouting technique, and according to that, the development direction of grouting technique is proposed.
