摘要: 为了对由煤炭开采引起的地表变形进行预计,基于概率积分法,利用最小二乘原理反演求取地表变形参数,对矿区地表变形作出高精度变形预计,得到地表变形等值线及开采沉陷预计三维模拟图。结果表明,最小二乘原理求取的变形参数可以高精度的对地表变形进行预计,可为开采沉陷进一步研究提供理论依据。

Abstract: In order to estimate surface deformation caused by coal mining,the method in this paper based on probalibility integral method to calculate the surface deformation paramters and estimate surface deformation of ming area in high accuracy is proposed by using the least squares inversion method.So,the controur surface deformation and 3D simulating diagram are obtained.The research results show that,the surface deformation can be estimated effectively by using the parameters of surface deformation at the basis of the least squares method.In addition,this research result can provide a theoretical basis for the further study on mining subsidence.
