某钨矿地压活动区采空区隐患治理研究
|
摘要
为防止某钨矿山地压活动区采空区所带来的地质灾害和安全隐患,本文以该矿区388中段I810采场为研究对象,进行采空区隐患治理研究。研究在采空区赋存现状调查的基础上,分析采空区治理条件与残留矿体开采条件,提出"崩落顶板造垫层+留隔离矿柱隔离采空区"的采空区处理技术方案和"大直径深孔凿岩压顶"的残留矿体回采技术方案,实现了地压活动区采空区安全处理,并为周边矿体安全开采打下了良好的基础。
In order to prevent the geological disasters and safety hazards caused by ground pressure activity of the goaf,the research on the hidden danger control of the goaf in a tungsten mine is carried out,which takes the stope I810 of level-388 as the research object in this paper.Based on the investigation of the current situation of the occurrence of this goaf,this paper analyzes the treatment conditions of the goaf and the mining conditions of the residual ore-body,puts forward the treatment of"crash roof cushion+residual isolation pillar isolation goaf"and the"large-diameter deep-hole rock drilling top column"technical scheme for residual ore-body respectively,by which we can dispose the ground pressure activity of the goaf safely and lay agood foundation for mining the surrounding ore safely as well.
