The invention discloses a micro-seismic monitoring energy checking method. The method comprises the following steps: arranging a plurality of micro-seismic sensors in a monitoring site; obtaining a coordinate A of each micro-seismic sensor, and constructing a three-dimensional coordinate system; arranging blasting points in the monitoring range of a micro-seismic monitoring station network, and determining coordinates B of the blasting points; blasting at the blasting points and forming a seismic source, and analyzing the coordinate C of the seismic source in the three-dimensional coordinate system through the micro-seismic monitoring station network; correcting an arrival time parameter Ti of each micro-seismic sensor until the coordinate C and the coordinate B meet a first allowable error condition; and on the basis of the checked coordinate C, correcting an energy calculation parameter Ki of each micro-seismic sensor, and enabling a micro-seismic energy value Ei monitored by each micro-seismic sensor and a
