DETECTION AND DETERMINATION OF MICROSEISMIC ACTIVITIES LOCATION BY WAY OF CONTINUOUS MAP-MAKING MIGRATION Russian patent published in 2011 - IPC G01V1/00 

FIELD: mining.

SUBSTANCE: first version of microseismic activity control method includes the following steps: definition of advent times obtained by model studies; receiving of one or more seismic signals with the help of one or more seismic detectors; performance of detection conversion of the received signals; mapping of detected conversion results that include detection of break with the aid of advent times obtained by model studies for making of continuously updated historic stereoscopy map in such a way that the map reflects the probability of seismic energy source presence that is some time present in the space; map values are estimated to define the location and time of microseismic activities. The second version of microseismic activity control method differs from the first one by the fact that additionally there performed is the conversion of received signals in relation to short-time averaging and long-time averaging and the results are mapped regarding the said conversion.

EFFECT: possibility of continuous on-line updating of microseismic activity map with exclusion of inaccuracy due to the use of data of two types recorded by the same detectors.
