摘　　要：本文分析了煤矿巷道底鼓诱发机制,阐述了目前底板治理的几种方法,并详细论述了锚注支护机理及其在巷道底板治理中的应用现状与发展动态。最后结合顾北矿648水平南翼(11-2)岩石轨道大巷底板治理工程实践,研究了底板注浆锚索与底角注浆花管联合支护技术在底板治理中的运用,底板位移动态监测结果表明,锚注支护技术在648水平南翼岩石轨道大巷底板治理中效果理想。This paper analyzed the mechanism of floor heave of roadway in coalmine,and illustrated some floor supporting methods. Further more,the application of bolt-grouting method in floor supporting is discussed.The bolt-grouting mechanism was analyzed, and the development trend of bolt-grouting technique was present.Finally,the application of bolt-grouting method in -648 level south wing rail roadway was given to research the bolt-grouting method in floor reinforcement of rock roadways.The monitoring result proved that the effect of bolt-grouting method is satisfying.
