中文摘要: 微震监测台网设计是系统能否成功应用的关键,直接决定了微震监测系统的应用效果。本文基于Sigma-Optimal方法对新疆大明矿业天湖铁矿的微震监测台网进行了设计及优化,使重点监测区域的定位误差较小且对较小震级事件具有较高的灵敏度。优化后微震监测台网的定位误差在9m左右,灵敏度可以达到-2.6矩震级,与现场应用情况一致,应用效果良好。

Abstract:Microseismic monitoring network design is the key to successful application of the system, which directly determines the application effect of microseismic monitoring system. In this paper, Microseismic monitoring network was designed and optimized based on the Sigma-Optimal method in tianhu iron ore of Xinjiang Daming mining group co. LTD. The location error of the key monitoring area was small and had a higher sensitivity to smaller magnitude events. The positioning error is around 9m and the sensitivity can reach the -2.6 moment magnitude. The location error of the optimized microseismic monitoring network was about 9m, and the sensitivity could reach 2.6 moment magnitude. It is consistent with the field application, and the application effect is well.
