厚煤层综放开采地表移动变形规律研究

Study on surface subsidence and deformation rule of thick coal seams by fully mechanized mining

为掌握厚煤层综放开采地表移动变形规律,高河煤矿在E1302工作面上方设置了地表移动观测站。通过对观测资料的分析与研究:给出了厚煤层综放开采条件下地表沉降曲线和最大移动变形值;求取了该矿地质采矿条件下地表岩移预计参数和角值参数;揭示了厚煤层综放开采条件下地表移动变形规律和特点。

In order to find rules of surface subsidence and deformation of thick coal seams caused by fully mechanized mining,surface observing station was set up on E1302 working face in Gaohe Colliery. And surface subsidence curves and maximum deformation values are presented from observation. On the basis,prediction parameters and strata movement angle are obtained under the geological and mining condition. Therefore,characteristics and rules of the surface movement and deformation of thick seams mined by fully mechanized caving mining are uncovered in the present paper.
