一种穿越煤矿采空区有限变形范围的选线方法

A Route Selection Method for Crossing the Limited Deformation Range of Coal Mine Goaf

随着我国煤矿开采规模的不断发展和交通工程建设的不断推进,煤矿采空区对公路、铁路等工程建设的影响日益突出。本文通过对半无限开采的煤矿采空区特征的分析,采用概率积分法对采空区沉降变形特征进行数值化展示,通过精准的地表移动变形测算,为公路、铁路工程提供一种自煤矿采空区的有限变形范围穿越的选线方法,以达到降本增效、节约土地资源的目的,具有良好的技术经济推广价值。同时建议开展公路、铁路工程在半无限开采煤矿采空区选线的概率积分法建模和软件开发,以便高效、快捷地完成选线任务。

With the continuous development of coal mining scale and construction of transport engineering in our country,the influence of coal mined⁃out area on highway and railway construction is increasingly prominent.This article analyzes the characteristics of goaf in semi⁃infinite coal mining and uses probability integration method to numerically display the settlement and deformation characteristics of goaf.Through accurate calculation of surface movement and deformation,it provides a route selection method for highway and railway engineering to cross the limited deformation range of goaf,in order to achieve the goals of cost reduction,efficiency increase,and land resource conservation.It has good technical and economic promotion value.At the same time,it is suggested to carry out the probability integration method modeling and software development of the route selection in the semi⁃infinite mining goaf for highway and railway engineering,so as to complete the route selection task efficiently and quickly.
