摘要
目前地表及浅层矿产资源不断减少,未来采矿必然要向深部进军。随着开采深度的增加,采矿作业面临“三高一扰动”的开采环境,严重影响采矿作业的正常生产,开展地压管理工作成为矿山生产的必要前提。从基础理论、监测手段、地压管理3个方面总结目前的相关研究成果,为矿山实际生产工作提供基础指导。基础理论基于动静力组合加载作用和温度-渗流-应力多场耦合作用2个方面展开,可以明晰地压活动的内在力学机理;监测手段基于应力应变监测系统和微震监测系统2部分展开,静态应力应变监测系统和动态实时微震监测系统相互配合,实现对生产过程中地压活动的有力监测;地压管理措施从地压调控方法和支护系统2个方面展开。明晰了目前深井开采地压基础理论和防控手段存在的问题,进而为后续研究指引方向,促进深井矿山的大力开采。
With the ongoing depletion of surface and shallow mineral resources,future mining efforts must inevit-ably venture deeper.As mining depth increases,operations face a"three high and one disturbance"environment,severely affecting normal production activities.Therefore,pressure management has become an essential prerequisite for mine production.The study consolidates current research achievements in 3 areas,including basic theory,monitoring methods,and ground pressure management,to provide foundational guidance for practical mining operations.Basic theory explores the internal mechanical mechanisms of ground pressure activities through dynamic-static load combinations and temperature-seepage-stress multi-field coupling effects.Monitoring methods discuss the deployment of stress-strain monitoring systems and microseismic monitoring systems,where static stress-strain monitoring and dynamic real-time microseismic monitoring work in tandem to effectively monitor pressure activities during production.Pressure management measures cover pressure regulation methods and support systems,clarifying current issues in fundamental theories and prevention measures for deep mine pressure and guiding future research to promote intensive deep mining.
