摘要
为满足各个领域对于矿产资源的需求,必须开采深层埋藏的矿产,深入研究不同围岩条件下的充填采矿方法。在围岩压力计算相关理论的基础上,构建六边形洞室压力的模型,研究六边形采矿方法开采体况的围岩稳定性,从充填高度、充填体强度、二次充填体强度、开采顺序等角度分析,最终确定最合适的开采方案。
In order to meet the needs of various fields for mineral resources,it is necessary to mine deep buried minerals and study the filling mining methods under different surrounding rock conditions.On the basis of the related theory of surrounding rock pressure calculation,the paper constructs the model of the pressure of the hexagon cavern,studies the surrounding rock stability of the mining conditions of the hexagon mining method,analyzes the filling height,filling strength,secondary filling strength,mining sequence,etc.,and finally determines the most suitable mining scheme.
