《中国煤炭报》1985年5月4日报道,适合于中小煤矿和压风动力不足的岩巷掘进动力单一化(电力化)作业线,已有12条投入使用,其中10条达到地方矿等级队标准,设备投资省,作业条件好,效率高,总的技术经济效益是明显的。鉴于所报道的作业线不仅对各级地方煤矿有参考价值,而且对于大型矿山建设的某些具体条件下,也很有借鉴意义,故本刊作如下综合的介绍。
China Coal Daily reported on May 4, 1985 that 12 coal-rock power leveling (electrification) lines suitable for small and medium-sized coal mines and under-pressured motive power have been put into operation, 10 of which have reached the level of local mine Team standards, equipment investment, good working conditions, high efficiency, the total technical and economic benefits are obvious. In view of the reports of the operating line not only for all levels of local coal mines have reference value, but also for some specific conditions of the construction of large-scale mines, it is also of great significance, so the publication is as follows comprehensive introduction.
