Research On Support Technology Of Blot-inject In Fractured Roadway Of Dongrong No.2Mine

With the reduction and lack of coal resources, increasing the depth of the currentcoal mining, deep mining and therefore the stress associated with the emergence of thestate from the shallow surrounding rock steady state changes to the deformed or broken.This east wing second deep mine tunnel reinforcement technology for broken rockengineering background, based on investigation and analysis of current support status inmining roadway, Dong Rong Mine No.2, researching the destruction mechanism andsupporting technology of broken roadway, Further studyt Broken of surrounding rockreinforcement mechanism, Proposed to the support technology of combining. Infractured surrounding roadway. Dong Rong No.2colliery and the deep were broken rockbolting and reinforcement technology engineering applications to solve the broken minetunnel rock crushing, not only the Dong Rong No.2colliery production safety to providetechnical support, mining for coal mine safety, surrounding roadway to provide a morecomplete combination of technical methods and processes for the control of roadwaydeep mining technology and proposed a new concept. The technology will improve thetunneling speed, reduce the expenditure of driving and maintenance, bring significanteconomic benefits...
