Study on the Underground Pressure Monitoring and Underground Pressure Control Measure for Jinfeng Mining

Abstract

Abstract: The laws of underground pressure activity of the stope and the entry are grasped by monitoring the underground pressure，supporting force and crack expansion of surrounding rock in the main roadway under intensively underground pressure，in Liaoning Jinfeng Gold Mining Co.，Ltd..Through monitoring subsidence of the roof surrounding rock and pressure of the supporting pillar in goafs formed in production，the rule of the roof subsidence displacement and the surrounding rock stability of the goaf are mastered，and the underground pressure control measure for the goaf is analyzed.The study provides a basis and method for treating the goaf.

Key words: Gold mine, The law of underground pressure activity, Underground pressure monitoring, Underground pressure control
