旋转射流风机消除回采工作面上隅角瓦斯积聚的可行性分析

Feasibility analysis of eliminating the Upper corner gas accumumulation in mining face by the rotary-jet fan

针对"U"型通风系统采煤工作面上隅角瓦斯积聚问题,结合旋转射流流动规律和采煤工作面环境,提出了利用旋转射流风机解决此问题的新途径,并给出了确定风机参数的方法。通过应用Fluent软件模拟,结果表明,利用旋转射流风机处理采煤工作面上隅角瓦斯积聚是有效的、可行的。

On account of the gas accumulation on the upper corner of coal face with ＂U＂ type ventilation system,based on the rotary flow rules and the condition of coal face,a new approach to solve the problem by the use of rotary-jet fan and a means to determine parameters of the fan were offered.According to the result of the simulation with Fluent,it is proved efficient and feasible to deal with the accumulation with the use of rotary-jet fan.
