煤矿冲击地压综合监测预警平台研究及应用

Research and application of comprehensive monitoring and early warning platform for coal mine rock burst

  • 摘要: 为了全面提高煤矿冲击地压监测预警精度,提升日常监测的自动化水平,以冲击地压发生载荷条件为切入点,提出对冲击启动载荷源开展分源监测的思路,开发了煤矿冲击地压分源权重综合监测预警平台。结果表明,以现场监测数据为基础,为每种预警指标赋予属性权重和等级权重,进而得到可随冲击危险性动态变化的综合权重,采用冲击地压分源权重综合预警方法,可解决人为定权易造成主观误差的问题,回避固定权重中部分指标被中和的情况,预警结果更加客观可靠;开发了集成接口融合、格式转化、统计分析、指标优先、权重计算、等级预警等功能为一体的冲击地压综合预警平台,实现了对微震、地音、应力、钻屑等多参量、多尺度预警信息的深度开发与警情智能发布,大幅提高了预警效率及效果,在多座典型冲击地压矿井进行了成果应用。

     

    Abstract: In order to comprehensively improve the accuracy of monitoring and early warning of rock bursts in coal mines and improve the automation level of daily monitoring, taking the load conditions of rock bursts as the starting point, the idea of carrying out separate source monitoring for the load source of rock burst was proposed, and a comprehensive monitoring and early warning platform for the weight of separate source of rock burst in coal mine was developed. The results show that, based on the field monitoring data, attribute weights and grade weights were assigned to each early warning index, and then the comprehensive weights that can dynamically change with the impact risks were obtained. The comprehensive early warning method of rock burst source weight can solve the problem of subjective error caused by artificial weighting, avoid the neutralization of some indexes in the fixed weight, and the early warning results were more objective and reliable. A comprehensive early warning platform for rock burst has been developed, which integrated the functions of interface fusion, format conversion, statistical analysis, index priority, weight calculation and grade early warning. The comprehensive early warning platform for rock bursts has realized the in-depth development and intelligent release of multi parameter and multi-scale early warning information such as microseisms, ground noise, stress and drilling cuttings, etc. and the intelligent release of warning information, which greatly improved the efficiency and effect of early warning. The results have been applied in the bump-prone mines.
