A simplex-method-based algorithim for determining the source location of microseismic events
The U.S. Bureau of Mines conducts basic and applied research related to predicting, eliminating, and/or controlling rock bursts in underground hard-rock mines and coal bumps in underground coal mines. An important element in this research is the development of a reliable and efficient microseismic source location technique. This report presents the results of a Bureau study to develop and evaluate a new algorithm to locate microseismic events based on the Simplex method, a linear programming technique. The technique was tested on both field data and simulated data. Microseismic event source locations obtained with this new Simplex-based algorithm are shown to have less error than those locations obtained using a least squares method. It is concluded that the Simplex approach to source location of microseismic events can be used effectively in microseismic monitoring.
