摘要
大冶市还地桥区域煤矿开采形成采空区变形及塌陷;造成区内居民房屋出现不同程度开裂变形、地面设施破坏。依据该区煤矿采空区勘查成果,对成因机制及稳定性、发展趋势进行分析评价,判断勘查区内的采空区及地表变形处于残余变形阶段,按今后50年地面累计变形情况计算结果将勘查区采空区划分为不稳定区、基本稳定区和稳定区并提出防治措施建议。
Mining activity results in ground deformation and collapse of mined out area of coal mines in the Huandiqiao region,Daye,Hubei.This paper has a discussion on genetic mechanism and development trend of the ground deformation and collapse and evaluates stability of the mined-out area based on field survey and divides the mined-out areas into unstable zone,basically stable zone and stable zone based on calculation of cumulative ground deformation in the next 50 years.Some control measures are put forward.
