摘　　要：矿场经过开采后,由于其填充所需费用较大,大多数开采矿单位选择将其废弃而不进行填充,且随着后期民采活动的进行,采空区规模逐渐扩大,极易造成垮塌,安全隐患较大,因此有必要对其稳定性进行风险评估,同时提出相应的治理措施。本文以湖南某锡矿地下采空区为例,通过对其进行现场调查以及通过物探对其老空区积水情况及主要构造破碎带发育情况进行实际勘测,随后采用Mathews图解方法和Barton极限跨度法对其稳定性进行综合评估,并给出合理的综合处理措施,为矿山采空区的安全、稳定以及风险评估提供相关理论基础。After mining,due to the high cost of filling in the mine,most mining units choose to abandon it instead of filling it.As the later civil mining activities continue,the scale of the goaf gradually expands,which is prone to collapse and poses significant safety hazards.Therefore,it is necessary to conduct a risk assessment of its stability and propose corresponding governance measures.This article takes the underground goaf of a tin mine in Hunan as an example.Through on-site investigation and physical exploration,the waterlogging situation and the development of the main structural fracture zone in the old goaf were surveyed.Subsequently,the Mathews graphical method and Barton ultimate span method were used to comprehensively evaluate its stability,and reasonable comprehensive treatment measures were provided.This provides a theoretical basis for the safety,stability,and risk assessment of the goaf in the mine.
