摘要
针对豹子矿大断面破碎围岩支护困难等问题,通过围岩支护技术对比,提出"注浆+锚索"联合支护技术,并进行现场工业性试验,通过顶、帮窥视和围岩变形观测,结果显示支护效果良好,为相似地质条件下破碎围岩支护提供借鉴经验。
In view of the difficulties in supporting large cross-section broken surrounding rock in Baozi Coal Mine,through the comparison of surrounding rock support technology,the combined support technology of "grouting + anchor cable" is put forward,and the field industrial test is carried out through roof and slope peeping and surrounding rock deformation observation.The results show that the support effect is good,which can be used as a reference for broken surrounding rock support under similar geological conditions.
