对于我国主要能源的煤炭工业,必须坚持机械化的方向,这是毫无疑问的,即使在国民经济调整时期,也要根据财力物力的可能,采取积极稳步的发展方针,不断提高技术装备水平。只有这样,才能促进煤炭工业生产建设的发展,适应国民经济对煤炭工业的要求。提高煤炭工业的技术装备水平,除了努力改进现有的老设备以外,更主要的就是积极地发展煤矿机械新产品,特别是井下采煤、掘进、运输、支护以及安全装备等煤矿专用设备。这是摆在煤矿机械科研、设计、制造工作者面前的一项十分紧迫和重要的任务。为了搞好这项工作, For our country’s major energy coal industry, we must adhere to the direction of mechanization. There is no doubt that even during the period of national economic readjustment, we should adopt a proactive and steady approach to development based on the possible financial and material resources, and continuously raise the level of technical equipment. Only in this way can we promote the development of the coal industry’s production and construction and meet the requirements of the national economy for the coal industry. In addition to efforts to improve the existing old equipment, more important is to actively develop new products for coal mine machinery, especially coal mine equipment such as underground coal mining, tunneling, transportation, support and safety equipment. This is a very urgent and important task that is placed before the scientists, designers and manufacturers of coal mine machinery. In order to do a good job,
