中文摘要: 针对非煤矿山采空区稳定性的问题,以皇华沸石矿采矿区为研究对象,运用三维激光扫描测量分析采空区矿柱、顶板、空区之间的关系。通过对采空区剩余变形估算,确定采空区影响范围,进一步分析采空区稳定性的影响因素为采空区岩体质量和空区自身参数;基于摩尔—库伦准则计算顶板的抗拉强度和柱体抗压强度,分析确定矿柱和顶板均处于安全稳定的状态。由于目前采空区范围已出现地面塌陷及地裂缝,进而对采空区采取封堵洞口和爆破处理的防治措施。
Abstract:Aiming at the stability of goaf in non-coal mines, this paper takes the goaf of Huanghua zeolite mine as the research object, measures and analyzes the relationship among pillar, roof and goaf by using Three-dimensional laser scanner. By estimating the residual deformation of the goaf, the influence area of the goaf is determined, and further analysis shows that the factors affecting the stability of the goaf are the rock mass of the goaf and the parameters of the goaf itself. The tensile strength of the roof and the compressive strength of pillars are calculated based on the Mohr-Coulomb criterion, and analysis results confirmed that both the pillar and the roof are safe and stable. As ground subsidence and ground fissures have appeared in the area influenced by goaf at present, the prevention measures include plugging the entrance and blasting treatment are adopted for the goaf treatment.
