自70年代中期我国煤矿开始引进综采设备以来,先后出现过采掘运系统不配套;掘进落后于采煤,运输落后于采掘;传统的巷道布置不能适应现代化采掘运生产工艺的要求等种种矛盾。在煤矿设计和实践中面临着不少新的问题。当前最突出的问题是辅助运输机械化问题。近几年来,随着开放政策的深入贯彻和煤炭科学技术的进步,各种新型运输设备不断出现。“七五”期间国家重点引进、试制、攻关的设备,如单轨吊、卡轨车、齿轨车等,有的正在某些矿井进行试验,有的已通过技术鉴定,将陆续投入使用。随着运输装备水平的提高以及今后的技术进步和
Since the mid-1970s, China’s coal mines began to introduce fully-mechanized mining equipment, over-excavation systems have been out of order; mining lags behind coal mining, transport lags behind mining; traditional roadway layout can not meet the requirements of modern mining and transportation of production and other contradictions. In coal mine design and practice, it faces many new problems. The most prominent issue at the moment is the auxiliary mechanization of transport. In recent years, along with the thorough implementation of the open policy and the advancement of coal science and technology, various new types of transportation equipment are constantly appearing. During the “Seventh Five-Year Plan” period, key state-introduced, trial-produced and research-related equipment such as monorail cranes, railcar trucks and gear rack cars are being tested in some mines. Some of them have passed technical appraisals and will be put into operation one after another. With the improvement of transport equipment and technological progress in the future
