Research And Application Of The Bolt-anchor Rope Unite Support In The Coal Tunnel Of Linxi Mining

Kailuan group linxi mineral industry company is a old mineral with 120 years mining historical, along with the increasing of mining depth, the tunnel pressure presents serious, tunnel maintenance difficulty, depending on the originally traditional shanty supporting can hardly guarantee the safety produce. On the basis of designing and constructing the anchor man pole- anchor man unites supporting, observing the transmutation of tunnel via installing the monitor and analyzing the dates, educe the conclusion that bolting support in depth high stress is a valid method, give the accordingly economic and reasonable support parameter and put forward the support countermeasure for mining tunnel with high stress at depth.
