我矿木梓园矿区位于海拔700～1000米的高山峻岭中,矿体赋存在海拔500米以下。为了解决开采过程中的通风系统问题,设计开凿一个高160米、断面7.5米~2与地表通风道相联的风井。由于缺乏经验,感到难度大。但经过工人和技术人员反复研究和实验,试制出一套电力载波控制器,另配上其它三套通讯联络装置,满足了安全生产的需要。在这次施工过程中,由于发挥了吊罐掘进队全体人员高度责任感和革命干劲,于1978年11月1日～12月8日只用了32个工作日,保质保量地完成了开凿通风井的任务。
Mine Mine Ziziyuan mine is located in the mountains of 700 ~ 1000 meters above sea level, the presence of ore bodies below 500 meters above sea level. In order to solve the problem of ventilation system during the mining process, a well of 160 m in height and 7.5 m ~ 2 in cross section is connected with the surface ventilation duct. Feeling difficult because of lack of experience. However, after repeated research and experiments conducted by workers and technicians, a set of power line controller was tried out and matched with the other three sets of communication contactors to meet the needs of safety production. In the course of this construction, due to the high responsibility and revolutionary power of all the personnel of the tunneling and digging team, it took only 32 working days from November 1 to December 8, 1978 to complete the excavation and ventilation on the basis of quality and quantity Well mission.
