东峰煤矿综放沿空留巷设计及其围岩变形量分析

Design of Gob-side Entry Retaining and Analysis on Surrounding Rock Deformation of Fully-mechanized Mining Face in Dongfeng Mine

根据东峰煤矿沿空留巷设计的地质与开采条件、采煤工艺、作业方式等资料,采用顶底板收敛量的影响因素的多元回归公式对其沿空留巷的围岩变形量进行分析和计算,并计算出回采巷道围岩变形分配。

Based on the geology and mining condition,mining technique,and operation mode of the design of gob-side entry retaining in Dongfeng Mine,multiple regression formula on factors of roof-and-floor convergence was used to analyze and calculate the deformation of surrounding rock.The deformation distribution of the surrounding rock was achieved too.
