摘要
基于葛泉煤矿锚注加固段和非锚注加固对比段巷道钻孔岩芯情况，分析了锚注加固对岩体完整性与准岩体强度的影响．根据巷道矿压显现与维护状况。
Based on the rock core drilling results in a roadway maintained by boltinggrouting and bolting methods in Gequan Colliery, the effect of boltinggrouting reinforcement on integrity and quasistrength rock mass is analyzed. From the stress behaviour of the roadway and its maintenance situation, it is proved that the improvement of rock mass integrity and strength is the main factor affecting roadway maintenance situation.WTHZ
