摘要
对曲面分布矿层进行地表移动预计时,通常是把曲面分布近似地当作平面分布来处理,例如把背斜构造形式的矿层简单地分为几个斜平面,然后利用多工作面开采地表移动预计方法进行预计,这样则会降低地表移动预计精度。本文介绍一种根据概率积分基本原理、利用曲线积分建立起来的地表移动预计新方法,并讨论了积分区间划分及计算坐标确定方法。
To predict subsidence caused by mining ore seam of curved surface distribution ,it is usually to take curved surface distribution as plane one approximately. For example, subsidence is predicted by the method for prediction of multi-face mining, with seam of anticlinal structure being simply divided into a few inclined seams. And obviously, the precision of predicted values of ground movement and deformation must be largely lowered. Based on the fundamental principles of the probability integration method, a new method for predicting subsidence is introduced in this paper. The method is established with the aid of curvilinear integral. And also the methods for delimiting integrated ranges and determining calculation coordinates are discussed.
