Some Developments and New Insights for Microseismic/Acoustic Emission Source Localization

Table 1

Characteristics and comparisons of the MSLM-WV and TM methods (from [80]).

Method	Known parameters	Unknown parameters	Advantages	Disadvantages
TM	Coordinates of sensors; arrivals of P-wave; premeasured velocity	Source coordinates; origin time of source	The minimum number of sensors is 4	Induce locating error by the premeasured velocity; consume massive manpower and material for blasting test
MSLM-WV	Coordinates of sensors; arrivals of P-wave	Source coordinates; origin time of source; average velocity	Weakening the locating error caused by premeasured velocity; save manpower and material for blasting test	The minimum number of sensors is 5
