摘　　要：地下采矿引起的地表塌陷和裂缝,严重威胁矿山生产安全,破坏地表生态环境。为了全面系统地研究地表塌陷的形成机理,从地下开采、降水疏干、大气降水、地下动水和爆破震动等几个方面分析了引起地表塌陷的原因。分析结果表明,北洺河铁矿地表塌陷是地下开采及其诱发的众多因素共同作用的结果。分析结果为地表沉陷规律研究和后期地表生态环境治理提供了理论依据。The ground collapse and cracks caused by underground mining severely threaten the safe in production and destroy the surface environment. In order to comprehensively and systematically study the mechanism of ground collapse, in this paper, from underground mining, dewatering, precipitation, moving groundwater and blasting vibration, the causes of ground collapse have been analyzed. The analyses show that the ground collapse is caused by underground mining together with the factor induced by mining in Beiminghe Iorn Mine. The analyzed results gave theoretical basis for studying the ground collapse and improving the ecological environment.
