摘要
建立全天候、高效率实时在线预警系统监测矿井地压活动,为减少、杜绝安全事故发生,维护员工生命健康有重要的现实意义。本研究以赣南某钨矿山为例,简要概述了矿山地压研究及管理现状,分析了采空区具有复杂、密集、贯通等特点,详细介绍了矿井微震监测预警系统建设目标、技术路线、建设实施、调试及试运行等情况。在实地调查、分析评估的基础上,兼顾合理性、可靠性和经济性等,圈定了3个重点地压监测区,选择了7个爆破点进行了爆破测试。数据表明:在检波器阵列覆盖范围内区域的定位误差较为理想。
It is of great practical significance to establish an all-weather and efficient online early warning system to detect mine ground pressure activities,which can reduce the occurrence of safety accidents and maintain the life and health of employees.The system realizes all-weather,high-efficiency and real-time online monitoring of mine ground pressure activities.Providing technical support for prevention and control of mine ground pressure disasters and effectively reducing accidents,it safeguards the life,health and safety of employees,and guarantees the long-term stability of mine safety production.This paper introduces the research and management status of the rock pressure of a tungsten mine in southern Jiangxi.On the basis of analyzing the characteristics of goaf,such as complex,dense and linked-up.The construction target,technical route,construction implementation,commissioning and trial operation of mine microseismic monitoring and early warning system are introduced in detail.This paper emphasizes the importance and urgency of using microseismic monitoring technology to strengthen theground pressure activity monitoring.The field investigation results determine three key ground pressure monitoring areas,with the principles of rationality,reliability and resource-conservation.Seven blasting points were selected for blasting test.The data show that the positioning error in the area covered by the geophone array is ideal.
