摘要
为了保证扎哈淖尔露天矿机道下煤炭回采的安全性,在详查工程地质资料,并根据实际揭露边坡体内分层岩体物理力学参数基础上,利用SLOPE/W软件中刚体极限平衡分析Morgenstern法分析与评价了机道北边坡稳定性;通过对机道北回采前后边坡稳定性的分析与研究,在保证其北边坡稳定的前提下,制定了全部采出、部分采出2种合理的回采方案;本着在安全的前提下,以煤炭资源开采效益最大化为原则,最终选择全部采出方案。
In order to ensure the safety of coal mining under the Zhahanaoer open-pit mine track,the engineering geological data is examined in detail,and the physical and mechanical parameters of the stratified rock mass in the slope are exposed,and the Morgenstern method is used to analyze the rigid body limit equilibrium in the SLOPE/W software.The stability of the north slope of the channel is analyzed and evaluated.Through the analysis and research on the stability of the slope before and after the northern mining of the tunnel,under the premise of ensuring the stability of the northern slope,two reasonable mining methods for all mining and partial mining are established.Based on the principle of maximizing the benefit of coal resource mining under the premise of safety,all extraction schemes will be finally selected.
