深部高应力煤柱区冲击地压动态控制研究

Dynamic Control of Rock Burst in High Stress Coal Pillar Area of Deep Mine

研究与实施了震动波被动层析成像反演动态预警冲击地压技术,制定了预警指标值与预警体系。通过该技术,可实现开采范围内冲击危险的动态预警,根据预警结果动态调整冲击危险治理方案与参数,可实现对冲击危险的主动动态控制。该技术体系在庞庄矿张小楼井成功应用于高应力煤柱区工作面的安全开采,取得了显著的效益。

The seismic wave passive tomographic inversion technology for rock burst dynamic warning is studied and implemented,and the prediction indexes and warning system are developed.By this technology,we can achieve the dynamic warning for rock burst in mining area.At the same time,the treatment schemes and parameters for rock burst danger can be modified and adjusted dynamically,which realizes the active control for rock burst.This system is successfully used in Zhangxiaolou Coal Mine in Xuzhou,which guarantees safety mining of work faces in coal pillar zones.
