摘　　要：提出以水力压裂、底板锚杆支护为核心的底鼓防治措施,通过水力压力切断采空区与运输巷顶板间应力传递路径,从而减少围岩应力集中程度;通过锚杆支护强化底板岩层稳定性及承载能力,并依据现场实际情况设计水力压裂以及底板锚杆施工方案。The bottom heave prevention measures with hydraulic fracturing and floor bolt support as the core are proposed to cut off the stress transmission path between the goaf and the roof of the transportation roadway through hydraulic pressure,so as to reduce the stress concentration of the surrounding rock.The stability and bearing capacity of floor rock stratum are strengthened through bolt support,and the construction scheme of hydraulic fracturing and floor bolt is designed according to the actual situation of the site.
