Abstract:
Aiming at the support problem of deep close distance overhead mining roadway at Ⅱ4 uphill transport in a mine of Xinwen Mining Group Company, using numerical simulation and field measurement methods, based on activity laws and deformation characteristics of deep roadway close surrounding rock in the process of overhead mining, the article studied the influence of Ⅱ1042 fully mechanized coal face mining on stability of Ⅱ4 rock uphill transport, researched the close overhead mining roadway deformation combined geological and mining conditions of Ⅱ4 transport uphill, and proposed reasonable control technology for Ⅱ4 transport rock uphill.
