针对煤矿通风系统存在的风机倒机过程中出现的短暂停风导致高瓦斯矿井井下瓦斯突出的问题,本文结合实际提出了在两个风道上方各增加一个百叶窗式的对空风门,从而实现倒机过程中井下风量基本不变,即不停风倒机;接着论文从风机系统与PLC监控系统联网的角度阐述了不停风倒机系统的动作流程。此种方案已成功应用于平煤集团下属的几个矿井,实践证明了该方案的可行性、实用性。
Aiming at the problem of gas outflow in high gas mine well due to the short-time wind stopped in the process of fan ventilation in the coal mine ventilation system, this paper puts forward the proposal of adding a louvered air damper above the two air ducts in order to realize the down- The downhole air volume in the process of the machine is basically the same, that is, the non-stop wind down machine; then paper from the fan system and PLC monitoring system networking point of view non-stop wind machine operation flow. This program has been successfully applied to several coal mines under the Pingdingshan Group, the practice proved the feasibility of the program, practicality.
