More Information
Summary:The invention provides a mine stratum hydraulic fracturing ground microseism monitoring method and system, and the method comprises the steps: obtaining a mining engineering plan of a mining area mining coal seam, and determining related parameters; acquiring plane coordinates and latitude and longitude coordinate information of a plurality of control points, and calculating seven-parameter correction values of mutual conversion of the latitude and longitude coordinates and the plane coordinates; defining a rectangular accurate monitoring area by taking the center of the initial monitoring area as an original point and the control points as vertexes, and recording plane coordinate values of the vertexes; according to an observation system and a speed model of a stratum, wave field records are obtained based on a given known seismic source in a monitoring area, and the distance between detectors is determined; discretizing the accurate monitoring area based on the geophone spacing, determining the arrangement
