摘要
为提高冲击地压预警的准确性及监测预警系统的智能化水平,以耿村煤矿为背景,研发了冲击地压“远-近”场监测预警系统。基于现场调研,分析了坚硬岩层和断层远场因素冲击地压致灾条件,将坚硬岩层破断和断层活化引起的应力变化视为远场影响,工作面附近煤体应力变化则为近场影响。采用加长锚索监测坚硬岩层和断层活动信息,结合微震、煤体应力、液压支架阻力监测系统,提出冲击地压“远-近”场监测方法。综合考虑“远-近”场监测信息,提出了冲击地压“远-近”场监测预警模型。建立了冲击地压“远-近”场监测预警系统架构,设计了冲击地压“远-近”场监测数据库。研发了冲击地压“远-近”场监测综合预警系统,实现了监测数据可视化功能、综合预警和报表自动生成功能。结果表明,该系统能够实现微震能量、煤体应力、支架阻力、坚硬岩层锚索拉力和断层锚索拉力等关键监测数据的实时采集、传输、存储和可视化,有效实现了耿村煤矿12240工作面的冲击地压综合预警及预警结果查询与信息发布。在试运行期间,系统成功预警了两次C级冲击地压事件。研究成果为耿村煤矿冲击地压的预防和治理提供了新的技术途径和理论支持。
To enhance the accuracy of rock burst early warning and improve the intelligence of monitoring systems,a“far-near”field monitoring and early warning system for rock bursts was developed,using Gengcun Coal Mine as the engineering context.This article is based on on-site research and analysis of the far-field factors contributing to rock burst disasters in hard rock layers and faults.The stress changes resulting from the rupture of hard rock layers and the activation of faults are classified as far-field effects,while the stress changes occurring in coal near the working face are categorized as near-field effects.By utilizing extended anchor cables to monitor hard rock layers and fault activity,in conjunction with microseismic data,coal stress measurements,and hydraulic support resistance monitoring systems,a“far-near”field monitoring method for rock bursts is proposed.This establishes the foundation for a“far-near”field monitoring method for rock bursts.By taking into account the comprehensive“far-near”field monitoring information,a“far-near”field monitoring and early warning model for rock bursts has been proposed.The framework for a“far-near”field monitoring and early warning system has been established,accompanied by the design of a database for“far-near”field monitoring of rock bursts.A comprehensive early warning system was developed,featuring data visualization,integrated early warning functions,and automated report generation.The results demonstrate that the system facilitates the real-time acquisition,transmission,storage,and visualization of key monitoring data,including microseismic energy,coal mass stress,support resistance,and anchor cable tension in hard rock layers and faults.It effectively provides comprehensive early warnings for rock bursts at the 12240 working face of Gengcun Coal Mine,along with capabilities for querying and disseminating warning results.During the trial period,the system successfully issued early warnings for two C-level rock burst events.The findings of this study provide a new technical approach and theoretical support for the prevention and management of rock bursts at Gengcun Coal Mine.
