深部开采地表沉陷规律模拟研究
Simulating research on rules of surface subsidence due to deep mining
摘要
Abstract
Through the research of structural mechanical model of the coal deep mining subsidence, the theoretical prediction model for the basin horizontal coal mining subsidence was put forward with two approximate calculation methods of whole and step.Using numerical simulation by changing the depth of coal mirung and the length of working face, the related data were compared by fitting calculation with field subsidence monitoring measurement.The new proposed method can calculate the parameters of predicting mining subsidence based on the structural mechanical model.give a reasonable mechanical description against the predicted data with the overlying rock strata mechanical parameters, and overcome the shortcomings of the classical model of probability integration method relied only on the statistical method to predict mining subsidence; so as to provides a reliable scientific basis to predict and control the deep safe mining and the surface subsidence.关键词
