【摘要】 提出了微震监测网络优化设计的5条一般性原则和运用Powell算法求解定位误差的方法。以平顶山十一矿SOS微震台网的优化布置方案为例,进行了定位误差数值计算,结果表明,定位误差保持在小于50m的水平,能够较准确地提供震源的基本信息和确定冲击危险的局部重点监测区域,表明对该矿微震监测台网的设计能够满足当前开采布局的要求,为下一步矿震活动规律监测和冲击危险的预测预报奠定了基础。更多还原

【Abstract】 This paper put forward 5 common principles for networking optimization design of micro-seismic monitoring and method for calculating orientation error with Powell arithmetic.Taking the optimization layout plan of SOS micro-seismic networking in 11th Mine,Pingdingshan as an example,this paper made numerical calculation for orientation error.The result showed that if orientation error was limited within 50m,basic information of seismic source might be obtained precisely and local key monitoring area of bursting danger be determined,which showed that the current design was fit for mining layout and provided base for monitoring behavior rule of mine seismic and forecasting rock-burst.更多还原
