露天矿地下采空区探测与治理技术应用与实践

Application and practice of detection and treatment technology for open-pit mine goaf

结合露天矿的自身特色和采空区治理的特殊要求,提出了以"物探先行、钻探验证、三维激光扫描精确定位"为原则的点式探测技术,给出了以安全厚度和稳定系数为评判准则的动态评价技术,确定了采空区分级、分类再处理的治理方案,通过应用与实践,基本形成了露天矿地下采空区探测、评价与治理技术体系,保障了露天矿安全高效生产。

Combined with the characteristics of open-pit mine and special requirements of goaf management, geophysical prospecting, drilling verification and 3D laser scanning accurate positioning were proposed, a dynamic evaluation technique based on judgment criteria of safety thickness and stability coefficient was obtained, and a goaf management plan after goal grading and classifying was determined. Through application and practice, complete sets of technical system of open-pit mine underground goaf detection, evaluation and treatment was achieved, which ensured safe and efficient production of open-pit mine.
