| description | The invention aims to provide a safety guarantee method for cooperation of open pit backfilling and underground mining in order to solve the problem of safety guarantee of cooperation of an existing open pit and underground mining. Aiming at a series of safety problems that complex hydraulic channels exist at the bottom of the open pit and a side slope, open pit backfilling and underground ore body collaborative stoping exist and the like, the invention provides a soft-hard combination mode to realize mutual independence of an upper space and a lower space, and the relationship between the open pit and the underground is thoroughly isolated. Wherein'soft 'is a filling body prepared by mixing full tailings with a cementing material; the'hard 'refers to pillars reserved by utilizing ore rocks, and the pillars comprise boundary pillars, roof protection pillars and panel pillars.
本发明的目的是针对于现有露天坑和地下开采协同的安全性保障存在的问题，提出一种露天坑回填与地下开采协同的安全保障方法。本发明针对露天坑底部及边坡存在复杂水力通道、露天坑回填与地下矿体协同回采等一系列安全难题，提出了采用"软硬结合"的方式实现"上"、"下"空间的相互独立，彻 |
