勘探技术研究所研究的内燃机械通风由我局102队承担了三个月（64年7—9月）的生产试验，实际工作时间共计106小时，机器运转正常。在坑道深150米时通风效果良好。在试验过程中同时解决了102队手掘通风问题，使生产转入正常，提高了生产效率，对完成全年手掘任务起了保证作用。现将试验的情况报导如下：
The internal combustion mechanical ventilation researched by the Institute of Exploration Technology was undertaken by the 102th Team of the Bureau for three months (July-September, 64th) production test. The actual working hours totaled 106 hours and the machine was operating normally. Ventilation works well when the tunnel is 150 meters deep. In the course of the trial, 102 teams of hand ventilation problems were solved at the same time, turning production into normality and improving production efficiency, which ensured the completion of hand-digging tasks throughout the year. Now test the situation reported as follows:
