小屯矿新风井贯通及误差分析

Error analysis and fresh air through the well of Xiaotun Mine

峰峰集团小屯矿经过多年开采,矿井变化巨大,通风阻力变大、通风断面缩小,造成矿井通风困难,并且矿井深部温度偏高,瓦斯涌出量加大,对通风的要求变高。针对这些问题,对矿井通风系统进行了技术改造,对新风井的贯通误差进行预计。

After many years of enormous changes in Fengfenf Group Xiaotun Mine, ventilation resistance became bigger and ventilation section shrunk which caused ventilation difficulty. In addition, deep temperature was higher and gas gushing amount increased which put forward higher requirements for ventilation. Based on these problems, mine ventilation system was conducted technical modification and breakthrough error of fresh air well was predicted.
