目前我国采煤工艺技术现状及其研究

20世纪90年代以来,我国煤矿以提高经济效益为中心,应用现代高新技术与采煤技术及装备相结合,加快推进煤矿生产现代化,进行了高产高效矿井建设,达到了世界先进水平。目前,我国煤炭产量居高不下,煤炭分布不均匀,采煤方法多样化,准备方式向多样化、大型化、集中化、单层化和全煤巷化发展,开拓方式向生产集中化、矿井大型化和运输连续化发展。

In the 20th century, 90 years, China~ coal mines to improve the economic efficiency, the application of modem high - tech and mining tech- nology and equipment combined to accelerate coal production modernization, conducted a high - yielding and efficient mine construction, has reached the world advanced level. At present, Chinab coal output remains high, the uneven distribution of coal, mining method diversity, prepared in ways to diversi- fy, large - scale, centralized, single - based and full - roadway - oriented development, open manner to produce centralization, mine large - settle contin- uous development and transport.
