本文利用顾桥煤矿1111(3)综采面地表移动观测站数据处理成果和外业数码相片,分析了建构筑物破坏现象产生的机理及其影响规律。得出相关结论:建筑物产生破坏和变形主要原因是曲率和水平变形的影响,在其作用下,采动区地面建筑物砖墙上出现裂缝。通过分析采动区上方建筑物砖墙上裂缝的分布规律,为合理加固和维修措施提供了依据,从而可以在建筑物受采动影响以前,根据地表变形预计的结果,对建筑物采取适当的措施,来减小地表变形对其影响。
In this paper, the data processing results and field photos of 1111 (3) fully mechanized mining face in Guqiao Coal Mine are used to analyze the mechanism of the failure of building structures and the influence law. The conclusion is drawn that the main reason of building damage and deformation is the influence of curvature and horizontal deformation. Under its action, cracks appear on the brick walls of ground buildings in the mining area. By analyzing the distribution of cracks on the brick wall above the mining area, it provides the basis for reasonable reinforcement and maintenance measures, so that before the building is affected by the mining, according to the expected result of the deformation of the surface, the building should take appropriate Measures to reduce the impact of surface deformation.
