Numerical Simulation of Outburst Prevention Effect of High-pressure Mini-jet Fracturing Coal

摘要：

　　Through ANSYS/LS-DYNA simulates mini-jet fracturing coal effect,this paper verifies that high-pressure mini-jet forms ahead hole on working face coal,which increases coal exposing area and relieves pressure inside the coal bed to creative conditions for gas relieving and flowing.Additionally underground stress,the coal around hole shifts to the hole space and enlarges the hole relieving pressure and gas exhausting scope further,which removes the coal outburst potential within the control scope and provides theoretical basis for studing the equipment of high-pressure mini-jet cutting hole against outburst.
