采用浅孔留矿采矿法的地下矿山四级矿量划分方法

Division Method for Level Four Ore Reserve of Underground Mine with Shallow-Hole Shrinkage Mining Method

以雅满苏井下矿采用的平底结构的浅孔留矿法为例,从一个矿块的采准、切割和回采工作的工程量、施工时间和矿块生产能力三个方面对独立划分存窿矿量,浅孔留矿法的矿山采用四级矿量的必要性进行分析。

The paper takes shallow-hole shrinkage method for the flat base structure used in underground mine of Yamansu as an example.From three aspects--the work amount of stope preparation,cutting,and stoping,the construction duration,and production capability of ore lumps,the paper carries out the analysis on the necessity of using level-four ore reserve for mine with shallow-hole shrinkage method for ore quantity of gallery which is divided independently.
