【摘要】：为了解新郑煤电矿井通风系统存在的问题,根据井下风量分配情况规划了4条测定路线,并合理选取了测风点与测压点进行通风阻力测定。分析新郑煤电通风阻力测定数据及结果表明:对于新郑煤电矿井通风系统,采用气压计基点法测试结果较为准确,西风井、北风井及矿井等积孔均大于2 m2,属通风容易矿井;西翼通风阻力集中在用风区,主要是14采区运输上山和回风上山2条通风线路均有调节设施,增加了通风阻力;北风井通风系统回风巷风量较为集中,风速较大,回风区阻力较大。针对2风井通风系统存在的问题分别提出了优化建议。
[Abstract]:In order to understand the problems existing in the ventilation system of Xinzheng coal mine, four measuring routes are planned according to the distribution of underground air volume, and the ventilation resistance is determined by selecting the air measuring point and the pressure measuring point reasonably. The analysis of the measuring data and results of Xinzheng coal electric ventilation resistance shows that: for the ventilation system of Xinzheng coal mine, it is more accurate to use the basic point method of barometer, the west air well, the north air well and the mine are all more than 2 m2, which belongs to the easily ventilated mine. The ventilation resistance of the west wing is concentrated in the area of using wind, mainly the two ventilation lines in 14 mining areas are equipped with regulating facilities, which increase the ventilation resistance, and the ventilation system of the north wind shaft has more concentrated air volume and higher wind speed. The resistance of return air area is large. According to the problems existing in the ventilation system of No. 2 air shaft, the optimization suggestions are put forward respectively.
