某工作面测风站位置的数值设计

Numerical Design of Air Measuring Station Location in a Coal Face

针对5-108工作面实际情况,采用数值模拟方法设计进回风顺槽测风站的合理位置。数值计算结果显示,进风顺槽测风站应布置在距风流汇合处120m-125m处,回风顺槽测风站布置在风流转弯之前10m。沿风流方向上,上风侧的扰动影响距离较长,测风员在测风时应注意避开上风侧有行人或车的情况。

According to the actual situation of coal face 5- 108,numerical simulation method was used to design the reasonable position of air measuring station in the head entry and the tail entry. The results show that,the reasonable location of air measuring station in the head entry is after the flow confluence of 120- 125 m,while 10 m before the turning corner in the tail entry. Along the airflow direction,the influence of disturbance in the upwind side has a long distance,we should avoid the pedestrians or vehicles in the upwind side when measuring the air flow.
