Underground microseismic monitoring of a hydraulic fracturing operation for CBM reservoirs in a coal mine [PDF]

open access: yesEnergy Science & Engineering, 2019
AbstractHydraulic fracturing can evidently improve the coalbed methane production in underground coal mines, but it is difficult to delimit the stimulated area accurately. In order to evaluate the stimulated area, microseismic (MS) monitoring technique is proposed to investigate the seismic responses of the induced fractures of hydraulic fracturing ...
