摘要
阐述了我国目前一些煤矿综采及巷道支护的现状,介绍了应用于普通矩形巷道的超前支架并分别应用于拱形、楔形巷道的异形巷道超前支架,为矿井的巷道支护及超前支架的研发积累了经验。
The paper makes an exposition of the existing situation of synthesis mining and tunnel supporting of big coal collieries, introduces forepoling roof supports for general rectangle tunnels, arch tunnels, cuneiform tunnels as well as abnormity tunnels; and also provides experience on the development of roof supports for tunnel supporting and forepoling supporting.
