摘　　要：露天开采矿山生产活动大规模挖损土地,矿石筛选、洗选形成大量废石,需要建设排石场存放产生的废石(土),这样不仅占土地资源,还形成崩(滑)塌、泥石流等地质灾害隐患,破坏地质环境,威胁矿山安全生产。通过对某露天开采的菱镁矿山为例,对采矿活动形成的排石场进行支挡设计,设置两道高大挡墙进行支挡以保证排石场的安全,根据计算各项指标参数满足规范要求。支挡工程降低或消除矿山排石场带来崩塌、泥石流等次生地质灾害,并为矿山地质环境治理进行客土覆盖绿化提供了平台,在其基础上进行恢复矿山地质环境恢复。Large-scale mining activities in open-pit mining have damaged land,and ore screening and washing have formed a large number of waste stones.It is necessary to build waste stones(soil)produced by the storage of stone dumps,which not only occupies land resources,but also forms geological hazards such as collapse(landslide)collapse and debris flow,which destroys the geological environment and threatens the safety of mine production.Taking an open-pit mining magnesite mine as an example,the support and retaining design of the quarry formed by mining activities is carried out.Two high retaining walls are set to ensure the safety of the quarry.According to the calculation,the parameters of each index meet the specification requirements.The support engineering reduces or eliminates secondary geological disasters such as collapse and debris flow caused by the mine dump,and provides a platform for the greening of soil reclamation cover for the geological environment management of the mine.On this basis,the recovery of mine geological environment is restored.
