摘要
根据邯郸矿区某矿工业广场下2103工作面非充分采动的技术条件,由工作面的宽深比对预计参数进行修正,采用修正后的参数按照概率积分法进行地表沉陷预计。由已推进部分造成的地面建筑物倾斜观测值的比较可以看出,参数选取合理。从地表变形规律可以看出,非充分采动的各种变形值都比充分采动要小,而煤层倾角则造成了下沉盆地向下山方向偏移,致使下山方向拐点处的建筑物损坏严重。
According to the technical conditions with insufficiency mining at 2103 working face under an industrial square of Handan mine area,prediction parameters are adjusted by the ratio of working face wide and depth.By using the revised parameters,surface subsidence is expected according to the probability integral method.It can be seen from the comparison of tilt observation values of surface construction caused by advancing part of the ground that the selection of parameter is reasonable.And it can be seen from the earth’s surface deformation law that various deformation values of insufficiency mining are samller than various deformation values of full mining.However,the subsidence basin turns to the downhill of coal seam because of the angle of coal seam,which will damage the buildings in inflection point of downhill seriously.
