摘要
为研究综采放顶煤条件下建筑物破坏规律,并为采动区建筑物的保护提供技术依据。结合五阳煤矿多个综放工作面的开采情况,对地表及建筑物的变形进行了现场实测,深入分析了不同结构的建筑物变形与地表移动的关系,根据现场实测资料,采用线性回归法分析得出:建筑物的下沉、倾斜与地表的下沉、倾斜是基本一致的,而建筑物的水平变形与地表的水平变形相关性差异较大,随着建筑物抗变形能力的加强,两者的相关性由强到弱,直至不相关。
In order to study and analysis the building failure law under the condition of the fully mechanized top coal caving mining and to provide the technical basis for the protection of the buildings above the mining active area,in combination with the mining conditions of the several fully mechanized top coal caving mining faces in Wuyang Mine,a site measurement was conducted on the deformation of the surface ground and buildings and a relationship between the different structural building deformation and the surface ground displacement was deeply analyzed.According to the site measured information,the analysis with the linear regression method found that the subsidence and inclination of the buildings and the subsidence and inclination of the surface ground were basically same,but there was a big mutuality difference between the building horizontal deformation and the surface ground horizontal deformation.With the anti deformation capacity of the buildings enhanced,the mutuality between the building and the surface ground would be from strong to weak and even would be not related.
