本文是在玉石洼铁矿大量调查采矿进路各种破坏形式与测试矿岩构面的基础上,利用赤平极射投影方法确定各组优势结构面及其组合交线的产状,研究分析各组结构面对采矿进路稳定性的影响,将玉石洼铁矿的岩体划分4类岩体结构,进而提出该矿围岩稳定性分级,为试验成功的简易光爆和以缝管式锚杆为主的喷锚网联合支护,以及以进路为单元组织生产的新工艺提出理论根据。 Based on the massive investigation of the various forms of damage and the test rock facets in the Jade Wa Wa iron mine, the authors used the stereographic projection method to determine the shape of the dominant structural planes and their combinations. The influence of the group structure on the stability of the mining approach, the rock mass of Jade Wa Wa iron ore is divided into four types of rock mass structure, and then the stability classification of the rock mass is put forward. For the successful experiment, Rod-based anchor and anchor net joint support, as well as to enter the unit for the production of new technology to provide a theoretical basis.
