风门是煤矿通风系统中一个重要组成部分。由它控制着矿井通风的流向。风门的工作状态一旦失常,将导致通风系统紊乱,直接威胁矿井安全。我矿是个百年老矿,又是多水平开采,巷道多,通风系统复杂。为节省人员,经过矿通风区职工的努力,既早实现了风门气动控制,无人看守。该系统虽然简单,但在多年的使用中 The damper is an important part of the coal mine ventilation system. It controls the flow of mine ventilation. Once the working condition of the damper is abnormal, the ventilation system will be disrupted and the mine safety will be directly threatened. Mine is a hundred years old mine, but also a multi-level mining, roadway and ventilation system complex.
