中文摘要: 运用微震监测技术对承德铜兴矿业下三中段采空区周边主巷道顶板裂缝区域进行监测,监测过程中有效预警了该区域发生的顶板冒落事件,通过对微震监测数据验证分析,可知监测区域内微震事件聚集程度以及微震事件数量变化、微震事件能量指数、岩体累积视体积与能量指数时间变化均可用于后续对承德铜兴矿业采空区周边巷道岩体稳定性分析与地压灾害危险预警的参考。
Abstract:In this paper, microseismic monitoring technology was used to monitor in the fracture area of main roadway roof around the goaf in the third level of Chengde Tongxing mining. In the process of monitoring, an effective early warning of roof caving in this area was proposed. Through the confirmatory analysis based on the microseismic monitoring data, it can be concluded that the aggregation degree and the variation of the number of microseismic events in the region, energy index of microseismic event,and the time variation characteristics of cumulative apparent volume and energy index can be used to analyze the stability of roadway around the goaf of Chengde Tongxing mining and as the reference of ground pressure monitoring hazard warning.
