摘　　要：在井筒中,矿井罐笼占据了部分空间.罐笼在升降运行时可能影响了周围的流场和压力场,从而导致产生动态局部阻力,进而影响井下通风系统.本文以流体动力学作为理论依据,运用nuent数值模拟软件和CFD计算模型,对井筒风速影响下罐笼停止和运行过程进行了模拟与分析.结果表明,井筒罐笼运行对井筒风流的影响很小,它产生的影响区域相对于井筒长度来说,是可以忽略的.While in the progress of up - and - down movement, the hoisting conveyance which occupies some space of vertical shaft causes piston - effect, leads to the change of the flow field and pressure field around the hoists, and generates frequently local resistance. According to the fluid mechanics, this paper uses the numerical simulation software to simulate the fluent in wellbore of ascending vessel stop and run time under the influence of wind speed CFD calculation model. Results show that shaft hoist vessel run will have impacts on the vertical shaft wind flow, the impact of its area relative to the length of the shaft, is negligible.
