基于概率积分法的卓子山矿区大采高综放采空区地表沉降预测
Prediction of surface subsidence in fully mechanized caving goaf with large mining height in Zhuozishan mining area based on probability integral method
摘要
Abstract
In order to study the surface subsidence law caused by the mining of deep and extra-thick coal seam working face,the surface subsidence parameter model along the dip and strike is constructed based on the probability integral meth-od,and the influence of different advancing distances and coal seam buried depth on the surface subsidence is analyzed by numerical simulation software.When the mining depth is small,the shape opening of the subsidence basin is small,and it is less affected by mining.When the mining depth is large,the opening of the subsidence basin is steep and greatly affected by mining.In the case of full mining,the mining depth has less influence on the maximum subsidence.The cloud map of the surface subsidence area is drawn,and the measured results of 844 mm and the theoretical calculation results of 843 mm are compared,which proves the rationality of the theoretical calculation.关键词
