今年九月十日至十五日，陕西地矿局在地质六队召开了“长巷通风评审会”，共有12个省局、16个队、三所院校34名代表参加了会议。与会代表参观了正在施工的坑道通风工作，听取了六队及武汉地院有关同志的报告，大家一致认为，陕西六队在独头长巷通风工作中成绩显著，在地质系统中处于遥遥领先地位。该队八一年以前，通风工作一直解决不好，巷道深度在595米时（断面2×1.8平方米）就用了4台5.5千瓦的通风机，直径300毫米塑料风筒间隔串联通风，每次爆破后排烟时间长达1—2小时，就这样还常常出现炮烟中毒现象。由于地质找矿的需要，该巷道逐年
From September 10 to 15 this year, the Shaanxi Bureau of Geology and Mineral Resources held a “Long Lane Ventilation Review Meeting” in the Sixth Geological Department. A total of 12 provincial bureaus, 16 teams and 34 representatives from three institutions attended the meeting. The delegates visited the ventilation work of the tunnel under construction and listened to the reports of the comrades of the six teams and the Wuhan Court. All agreed that the Shaanxi Six teams achieved remarkable results in the ventilation work of the autonomous alley and are in the leading position in the geological system . Eight years ago, the team worked hard to solve the problem of ventilation. When the tunnel depth was 595 meters (2 × 1.8 square meters in section), four 5.5-kilowatt ventilators were used and the diameter of the 300-mm diameter plastic tube was communicated in series. After the blasting time up to 1-2 hours of smoke, it is also often the phenomenon of gunpowder poisoning. Due to the geological prospecting needs, the roadway year after year
