The monitoring of microseismic activity in geologic formations of underground mines has become a major area of interest of the mining industry. The use of this technology relies on recognition of the arrival times of seismic waves at remote sensor locations, and using the characteristic velocities of the formations, calculating the point of origin of the microseismic event. The accuracy of the technique is subject to limitations of measurement precision and to errors in the determination of the correct phase of the incoming signal associated with the first arrival of the seismic wave. The value of the simplex technique for microseismic monitoring is illustrated through presentation of experimental results in solving for source location for a series of known-source test blasts.
