摘要
为了明确可开发利用煤炭资源储量的范围、分布及发展潜力,查明井田产能建设的煤炭资源储量,规划井田开采方案,为煤矿资源储量的可持续发展提供可靠保障,以新疆巴里坤矿区某井田A1煤层为研究对象,提出了一种基于3DMine软件的三维地质建模与储量估算方法。该方法首先结合已有地质资料和钻孔数据,建立了地质数据库,圈定了矿体边界,构建了矿体三维模型;然后将矿体模型分解为离散的块体组合模型,采用普通克里格空间插值法估算煤炭资源储量。结果表明:普通克里格法计算煤炭资源储量能够充分利用样品信息,与传统地质块段法相比较而言,估算结果较为可靠;该方法综合考虑了煤样的形状、大小及煤样与储量块等变量之间的空间结构特征,能够为井田采矿设计与规划提供参考。
In order to obtain the information of reserve scope,distribution and development potential of available coal resources,grasp the information of coal resources reserve of mining field productivity construction,plan the mining scheme of mining field,and to provide the reliable guarantee for the sustainable development of coal resources,taking the A1 coal seam of a mining field of Blikun mining area,Xinjiang as the research example,a new three-dimensional geological modeling and reserve estimation method based on 3DMine software is proposed. Firstly,the geological database is established,the ore-body boundary is delimited and the three-dimensional ore-body model is built based on the existing geological information and drilling data; Secondly,the ore-body model is divided into the discrete block combination models,and the ordinary kriging spatial interpolation method is used to estimate coal resources reserve. The research results show that,the samples＇ information is considered fully during the process of estimating coal resources reserve based on ordinary kriging spatial interpolation method.Compared with the traditional geological block method,the estimating results by the ordinary kriging spatial interpolation method is more reliable; Besides that,the ordinary kriging spatial interpolation method considers the shape and size of coal samples and spatial structural characteristics between coal samples and the variables such as reserves blocks. Therefore,it can provide some reference for mining design and strategic planning.
