复杂条件下综放工作面开采地表沉陷实测

Site Measurement on Ground Subsidence Induced by Fully-mechanized Caving Coal Mining under Complex Conditions

为研究煤炭开采对地表建筑物等构筑物的影响和破坏,获取相应地区采煤工作面地表移动规律,提高煤炭资源回收率,控制地表沉陷,在综放工作面上方建立相应地表移动变形观测站,在进行回采时多次进行地表移动和变形观测获得相应的数据,并对数据进行了分析。

In order to increase the recovery rate of coal resources, control ground subsidence, study the impact and damage on ground buildings beyond coal mining workface ,via a method of build ground movement and deformation observation stations and regular repeated observation of ground movement and deformation during the time of coal resources recovery.
