金凤矿业地压效应监测及地压控制方法研究

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

通过对辽宁金凤黄金矿业有限公司井下受集中地压作用的主运输巷道的地压、支护反力和围岩裂缝扩张的监测,掌握了采场和巷道地压活动规律。对生产形成的采空区进行顶板围岩沉降和支撑柱压力监测,掌握了矿石回采中顶板下沉位移变化规律和采空区围岩稳定状况,分析了采空区地压控制措施,为空区处理提供了依据和手段。

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.
