| 摘 要： | 现有矿业软件的储量估算模块核心方法主要基于地质统计学。文章以河北迁安羊崖山铁矿床为例,通过3DMine软件在数据资料准备、变异函数确定、块体模型构建及储量报告等多方面的应用,规范了矿业软件在资源量估算方面的工作流程。利用普通克里金法和距离幂次反比法分别进行品位插值,完成资源量估算;并与传统储量估算结果进行比较,分析产生误差原因,建立了开采境界模型,计算了矿山开采储量和保有储量;利用赋值参数分析矿体控制程度,指导未来探矿工程重点部位。

| Abstract: | The key methods of the reserve estimation module of the present mining software are all based on geostatistics. This paper takes Yanglashan iron deposit, Qianan county, Heibei province as an example. Based on application of 3DMine software to data and information preparation, variogram determination, building of the block model and compiling of reserve report the work flow of the reserve estimation by software is standardized. Ordinary Kringing method and inverse distance squares method were used to made grade interpolation respectively. The reserve estimation is finished. Compared with the result estimated by traditional method we analyzed the reason of errors. Then 3D pit model is built, the mining reserve and recoverale reserve calculated. Parameters of the assigned value is used to analyze control of ore bodies so as to guide the future prospecting works. |
