Research on dynamic shrinkage of hydraulic flushing borehole based on fractional Maxwell creep model

Hydraulic flushing and permeability improving technology has been widely used in gas extraction in soft coal seams. However, the strength of soft coal is low, so creep deformation is easy to occur, resulting in serious borehole shrinkage and thus affecting gas extraction efficiency. Aiming at the sh...
