摘要
结合瑞隆矿的地质条件,采用有机材料注浆、无机材料注浆和预应力锚索几种不同性能支护的组合结构对副井马头门及井筒进行锚注联合加固,取得了理想的效果。
Combined with the geological conditions of Ruilong Coal Mine, by using different performance support composite structure which were organic material grouting, inorganic material grouting and prestress anchorage cable, the ingate and shaft of the auxiliary shaft were anchored, grounted and reinforced.
