Research on negative pressure distribution laws of drainage borehole with different deformation and instability
A solid-flow coupling model of gas drainage was established which synthetically considered dynamic variation of negative pressure of drainage borehole according to variation mass flow characteristic of gas flowing in the borehole and its deformation situation. Taking Xi'an Coal Mine as an examp...
