【摘要】 研究采空区治理与矿体协同回采方案，不仅能够消除隐伏采空区的安全隐患，也可以提高地下金属矿山的开采效率。以包头某矿山的采空区群治理为工程背景，构建了采空区拱形冒落力学模型，并采用数值模拟方法验证协同回采方案的可行性。研究结果表明：在协同回采方案完成条件下，采空区矿柱以及顶板会逐渐发生零星冒落，形成覆盖岩层充填采空区群，实现了采空区群治理与矿体协同开采的目标。研究结果可为隐伏采空区影响下矿体安全高效回采提供技术参考。更多还原

【Abstract】 Studying the scheme of gob treatment and orebody coordinated mining could not only remove the safety hazard of hidden gob, but also improve the mining efficiency of underground metal mines. Took goaf group treatment of the iron mine in the Baotou city as the engineering background, a mechanical model of goaf arch caving was built, and then the feasibility of collaborative mining scheme was verified by numerical simulation. The results showed that the pillar and roof of goaf would granually occurred sporadic caving, and then the caving rock would full the goaf, realizing the goaf group management and orebody mining. This research results could provide technical reference for safe and efficient mining of orebody under the hidden goaf.更多还原
