Advances in fundamental theories and prevention for deep mine pressure
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.
