基于矿体赋存条件的三级矿量优化管理

Optimize the management of three grade reserves based on ore body occurrence conditions

三级矿量的合理保有量一直是困扰国内矿山企业的一大难题。文章结合矿体的赋存条件对合理确定地下矿山三级矿量的问题展开分析,提出有效备采矿量的概念,从矿体水平面函数的角度对三级矿量进行优化管理。通过金山店铁矿的例子,论述了三级矿量的保有量不但要符合回采时间和开采顺序的要求,还要根据矿体赋存条件的复杂程度进行综合考虑。

Reasonable tenure of three grade reserves has been a major problem plagued the domestic mining enterprises. This article analyzes the problem of reasonably determining the underground mine three grade reserves combined with the occurrence conditions of the ore body, putting forward the concept of effective stoping reserves to optimize the management of three grade reserves from the angle of the ore body horizontal plane function. Through the example of Jinshandian iron ore discussing the tenure of the three grade reserves not only to comply with the requirements of the stoping time and the mining sequence, but also consider the complexity of the ore body occurrence conditions.
