Spontaneous heating and gas drainage on a coal face with "four-gateroad" and overlying drainage tunnel
Based on the 15101 working face, this paper investigates coupling effects between gas drainage and spontaneous heating of residual coal in goaf due to the suction pressure in overlying drainage gateroad in the face with four-gateroad system. Extensive numerical simulations are conducted by setting u...
