1988年12月份,许昌市科委组织有关工程技术人员到白庙煤矿井下进行了实地排放瓦斯检查验收,评议认为:“T”型风筒排放瓦斯法与其它排放瓦斯法比较,有多方面的优越性,它设计合理,制作简单,适应性强,操作方便,风流稳定,排放安全。1989年春季,评定为许昌市科学技术进步三等奖。截止1991年6月份,已有地方国营煤矿和乡镇煤矿近100对矿井,掌握、推广了“T”型风筒排放瓦斯的方法。现把具体排放方法介绍于后。
In December 1988, Xuchang Municipal Science and Technology Commission organized the relevant engineering and technical personnel to carry out on-site gas emission check and acceptance at Baimiao Coal Mine. According to the assessment, “T” type gas discharge pipe method compared with other emission gas methods, there are many aspects Superiority, it is reasonable in design, simple in production, strong in adaptability, convenient in operation, stable in flow and safe in discharge. In the spring of 1989, it was assessed as the third prize of science and technology progress in Xuchang City. As of June 1991, there have been nearly 100 mines in state-owned coal mines and township coal mines, and the method of “T” -type blower gas drainage has been grasped and promoted. The specific method of discharge is introduced later.
