摘    要:许昌县武庄村一村民家院内发生地面塌陷。利用地面及井下调查、测量及地面物探等手段,分析了该坍塌原因。该地区地质构造复杂,下部有多个断裂与背斜,岩体破碎;地下采矿活动和振动导致上伏岩层变形塌落,促使地面下饱水松散层在自身重力及静水压力的共同作用下发生塌陷。

关 键 词:地面塌陷  采矿活动  形成机理

Abstract:A ground collapse occurred to the courtyard of a villager in Xuchang,Henan.The reasons for the collapse are explored on the basis of the surface and subsurface investigations,surveying and geophysical prospecting.Results show that the area is characterized by complex geological structures,with many faults,anticlines and rock ruptures in the underground.The underground mining activity in this area has resulted in the deformation of overlying stratum.Thus the underground saturated soil collapsed under the combined effect of its own gravity and hydrostatic pressure.
Keywords:Ground collapse  mining activity  formation mechanism
