基于概率积分法的开采沉陷预计分析

摘要

首先介绍了概率积分法计算地表移动变形的基本原理,其次运用VB语言编制了计算矩形工作面地表移动变形的预计程序,并结合鲍店泗河堤坝下采煤实例,预计了堤坝沉陷及变形量,并计算了堤坝回填土方量,以期为矿区开采奠定基础.%The paper first introduces principle of calculating ground surface's deformation and shift by using probability-integral rnethod, and then formulates rectangular face movement and deformation of surface by VB language, it anticipates subsidence and deformation of the dam and calculates backfilling earthwork dam combining practical example in Baodiansihe dam, it aims to establish foundation for exploitation in mining area.
