综放开采村庄房屋破坏规律与保护技术

为了解决综采放顶煤条件下地表移动剧烈,地表的移动变形值和动态变形值大的问题,在五阳煤矿7511工作面上方建立地表移动观测站,进行地表移动观测,选择了4处试验观测区进行房屋采动破坏观测,系统研究了综采放顶煤条件下村庄房屋破坏规律、村庄建筑物保护技术。结果表明:新建村庄经历了老采空区的残余沉陷变形影响和7511、7512综放工作面开采的采动波及影响,所有房屋没有出现裂缝。利用采空区上方塌陷区附近就近建设抗变形村庄,是合理解决综放开采条件下村庄下采煤的有效途径之一。

Village Buildings Destroyed Law and Protection Technology of Underground Fully Mechanized Top Coal Caving Mining

In order to solve the surface ground serious displaced,the surface ground high displacement and deformation and the high dynamic deformation problems under the condition of the fully mechanized top coal caving mining,the surface ground mobile observation station was set up above No.7511 coal mining face of Wuyang Mine for the surface ground mobile observation.There were four test observation zones selected for the mining failure observation of the buildings.The paper had a systematic study on the destroyed ...
