矿山顶板安全预警新体系研究
|
摘要
将地质超前预报技术推广运用到矿山顶板安全检测中,查明掌子面前方的异常情况,为采场、巷道设计及安全监控提供超前信息。围绕微地震监测技术形成新的矿山安全管理体系,通过监测数据分析围岩稳定性,对矿山进行三级预警,克服了传统安全管理静态、定性的缺点,实现远程、动态、实时跟踪监测,并能对微地震事件进行三维可视化显示,对指导矿山安全生产、提高矿山安全管理水平及降低灾害损失具有重大意义。
The technology of the geological advanced prediction is applied to the safety monitoring of mine roof to find out the abnormal ahead of the working face and provide advanced information for the design of stope and tunnel,and the safety monitoring and control.Combined with microseismic monitoring technology,a new mine safety pre-warning and monitoring management system can be formed.And with the monitoring data,the stability of the surrounding rock can be analyzed to achieve the three-level pre-warning for mines.Therefore,the shortcomings of static and qualitative of traditional mine safety management are overcome,and the remote,dynamic,real-time tracking monitoring are realized in mines with three-dimensional visualization of the microseismic events achieved.It is of great significance to guide the safe production in mines and improve the level of safety management and reduce the mine disaster loss.
