摘　　要：我国榆林等地区遗留有大量房采采空区,其所处的岩体系统是一个具有潜在能量释放危险的、可造成人员伤害的危险源,随着时间推移可能会诱发采空区失稳灾变。为此,以危险源辨识与控制理论为指导,分析了房采采空区危险源及其构成要素,对危险源分布进行分类,并提出了不同条件下的采空区治理技术。分析结果表明:房采采空区中部分可能导致事故的因素以及危险源存在的场所,主要包括煤柱破坏区、顶底板破坏区、积水影响区、自然发火区、采动影响区,以及建(构)筑物、公路下等。对应的隐患治理主要有采空区地面注浆治理技术、采空区残留煤柱充填回收技术、采空区露天剥离治理技术和未塌采空区顶板崩落治理技术等。A large number of room mining gobs left over in China Yulin and other regions, the rock mass system of the room mining gob was a hazard source which had potential energy release and might cause personnel injury, and with the lapse of time, it might induce gob instability and disasters. In this paper, guided by the identification and control theory of the hazard source, the hazard sources in the room mining gobs and their components were analyzed, the hazard source distribution was classified, and the control technologies for the room mining gob hazard under different conditions were put forward. The results showed that in the room mining gob, some places where the accidents might occurred and the hazard sources might exist mainly included the coal pillar failure zone, the roof and floor failure zone, the water affected zone, the spontaneous ignition zone, the mining influence area, the areas under buildings, structures and roads and so on. The corresponding control technologies for the hidden danger in the room mining gob mainly included the surface grouting into the gob, the gob residual coal pillar filling and extraction, the open-pit stripping of the gob, the roof control of the undamaged gob and so on.
