|
摘要
通风系统对于保障井工煤矿的安全生产至关重要,为应对矿井巷道通风功能失效造成的各种危害,本文首先针对巷道通风功能失效的机理展开分析,对失效3个阶段的失效模式展开分析,进而利用基于失效风阻值的失效判别准则,得出巷道风阻值常规变化规律曲线并展开分析,最后对矿井通风管理部门的通风失效管理提出合理化建议。
The ventilation system is very important to guarantee the safety production of well coal mine, in order to deal with the harm caused by the failure of ventilation function in mine roadway, this paper firstly analyzes the failure mechanism of roadway ventilation function, analyzes the failure mode of failure three stages, and uses the failure criterion based on the failure wind resistance. The rule curve of the wind resistance of roadway is obtained and analyzed, and finally the reasonable suggestions are put forward for the ventilation failure management of mine ventilation management department.
