Study on the Quality Classification and Rock Support Parameters of Complex and Variable Fractured Ore Bodies
Taking the related ore body rocks of Chifeng Chaihulanzi Gold Mining Co.,Ltd.,as research subject the stability classification of its complex and variable fractured rock mass was carried out,reasonable access parameters were determined,and safe,reasonable,and economical tunnel and mining support parameters were found.The results of the relevant rock mass quality and rock support parameters were obtained,improving the stability of the surrounding rock and tunnel in the mining area,reducing the investment and production costs of support,and achieving safe,efficient,and economic recovery of fractured steeply inclined thin deposits.
