为了快速准确地反映煤矿井下各采掘区域的矿震时空强演化特征,以便及时预测冲击矿压危险性并采取解危措施及指导实际生产,在考虑冲击震动破坏最大动力响应范围的前提下,根据矿震与采掘活动的对应关系,给出了矿震监测分区原则,提出了基于坐标旋转的矿震分区监测方法,采用编程工具Delphi直接调用数据库,实现了矿震数据在不同时间段、不同空间区域及不同能量级别上的快速查询筛选,并对筛选数据进行分析得出规律。以华亭煤矿250103工作面回采期间监测到的矿震数据为研究对象,利用矿震分区监测方法进行分析,结果表明:矿震分区监测方法能快速准确地反映煤矿井下各采掘区域的矿震时空强演化特征,达到预测预报和指导实际生产的目的。
In order to quickly and accurately reflect the temporal and spatial evolution characteristics of mine-mining seismicity in each mining area in coal mine in order to predict the rock burst risk in real time and take measures to solve the danger and guide the actual production, under the premise of considering the maximum dynamic response range of the impact vibration damage, The relationship between mine and mining activities, the principle of mine subsidence monitoring and partitioning is proposed, and a monitoring method based on coordinate rotation is proposed. By using the programming tool Delphi to directly call the database, the mine seismic data can be obtained at different time and space Regional and different energy levels of rapid query screening, and the screening data analysis of the law. Taking the coal mine seismic data collected during the coal mining 250103 working face of Huating Coal Mine as the research object and using the monitoring method of mine and seismic subarea, the results show that the monitoring method of mine and seismic subareas can quickly and accurately reflect the time-space intensity of mine-induced earthquakes in each mining area of coal mine Evolution characteristics to achieve the purpose of forecasting and guiding actual production.
