采场调压可改变采场内气体流动的状况，抑制采空区自然发火。笔者采用Ｗａｒｄ 非线性运动方程，建立采场调压数学模型，利用有限元法对其进行求解。通过对小恒山煤矿东正巷出口的调压进行计算机模拟，从而掌握火区内部参数的变化趋势，及时预测调压潜力及效果，指导调压措施的进一步实施。
The stope pressure regulation can change the gas flow in the stope, and restrain the spontaneous combustion in the goaf. I use Ward nonlinear equations of motion, the establishment of mathematical model stope pressure regulator, using finite element method to solve them. Through the computer simulation of the pressure regulation in the east exit of Xiaoshan Coal Mine, the variation tendency of internal parameters in the fire area can be grasped, the potential and effect of pressure regulation can be timely predicted, and the further implementation of pressure regulation measures can be guided.
