摘要
以赤峰柴胡栏子黄金矿业有限公司相关矿体岩石为研究对象,对其复杂多变破碎岩体进行稳定性分级,确定合理的进路参数,寻找安全、合理、经济的巷道及采场支护参数,从而得到相关岩体质量的结果以及岩体支护参数,提高采场上盘围岩和巷道的稳定性,降低支护投入和生产成本,实现了破碎急倾斜薄矿床的安全、高效、经济回采.
Abstract
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.
