摘要
深部煤层进行大采高综采过程中,较大的采高有利于煤层的高效开采,同时过大的采高对围岩的稳定性造成影响.为确定合理的大采高数值,采用仿真模拟的形式对四种不同采高时煤壁及超前巷道的变形进行分析,从而选取合理的采高,保证煤矿的高效安全开采.
Abstract
In the process of fully mechanized mining with high mining height in deep coal seams,high mining height is beneficial for efficient mining of coal seams,while excessive mining height has an impact on the stability of surrounding rocks.To determine a reasonable high mining height value,simulation was used to analyze the deformation of coal walls and advance tunnels at four different mining heights,in order to select a reasonable mining height and ensure efficient and safe mining of the coal mine.
