无底柱分段崩落采矿法三级矿量的合理计算

自20世纪60年代引进无底柱分段崩落采矿法以来，矿山生产组织中三级矿量的合理确定一直没有得到解决，致使一些矿山在生产组织中形成了三级矿量失调，影响了矿山的生产。为此，在对国内相关矿山调研的基础上，针对无底柱生产特点，形成了专门用于该采矿方法的三级矿量计算方法，为我国地下矿山的生产组织提供了依据。

Calculation of Rational Third-class Ore Reserve of Pillarless Sublevel Caving

Since the introduction of pillarless sublevel caving method in the sixties of twenty century,the rational determination of third class ore reserve in mine production organization hasn't been solved,leading to an unregulated third class ore reserve in the production organization at some mines,which has affected the mine production.Therefore,based on the investigation of related domestic mines and in light of the characteristics of pillarless production,a calculation method of the third class ore reserve specially for this mining method was formed,providing the basis for the production organization of China's underground mines.
