摘要
本文在相似材料模拟实验,有限元计算和生产实践基础上,研究了缓倾斜煤层群上行开采岩层运动发展规律和支承压力分布规律,通过分析和比较得出:上行开采的岩层运动特征和支承压力分布特征对采场围岩的平衡和稳定、顶板管理和控制、巷道布置和维护、支架——围岩关系、工作面和巷道保护都极为有利;是一种既安全又经济的开采方法。
On the basis of similar material simulation experiment, finite element calculation and preduction practice this paper studied the laws of rock movement and abutment pressure distribution of the mining of gently-inclined coal seam group in ascending order. We obtain, through the analysis and comparisons that the features of rock movement and abutment pressure distribution in ascending mining are favourable to the balance and stability of surrounding rock of working faces, the roof control, roadways layout and their maintenance, the relation between supports and surrounding strata, etc., it is a safe and economic mining method
