摘要
露天矿山开采过程中易形成高陡边坡,在暴雨等极端情况下可能会发生崩滑现象,对人员、财产及采矿活动造成极大的威胁,因此有必要研究危岩体发育的地质环境条件、规模特征等,评价其稳定性及发展趋势。本文以广西荔浦钟家书采石场为例,查明采场内存在3处危岩带,整体稳定性较差,在采矿爆破、强降雨及风化等其他不利因素作用下,极易发生倾倒式、滑移式崩塌,严重威胁山体下部工作人员的生命财产安全。
In the process of open pit mining,it was easy to form high and steep slopes,while collapses and sliding may occur in extremes such as rainstorm,which posed a great threat to personnel,property and mining activities.Therefore,it is necessary to study the geological environment conditions and scales of the development of dangerous rock bodies,and to evaluate their stability and development trends.This article took the Zhongjiashu Quarry in Lipu,Guangxi as an example to identify three dangerous rock zones.The overall stability was poor.Under adverse conditions such as mining blasting,strong rainfall,and weathering,toppling and sliding collapses were prone to occur,seriously threatening the life and property safety of workers in the lower part of the mountain.
