摘要:
采空区是固体矿产开采过程中已被开挖的所留下的采场、硐室等,采空区的储量编录是矿山储量动态管理的基本要求,准确的储量计算结果可有效指导矿山后续的生产工作,提高经济效益,但目前国内各矿山大多采用简单的几何计算方法求取采空区储量,无法准确、客观地评估矿山的资源储量情况,为了精确估算采空区储量,以新疆某矿区为例,首先分析了适合建立采空区的三维模型方法,以及固体矿产储量估算中采空区建模的2种方式:剖面法和中段法; 建立模型后,将基于地质统计学建立的矿体三维模型和采空区模型进行布尔求交,根据切割后模型,体积加权计算采空区储量; 最后通过实例对比采空区和剖面法三维矿体模型求交结果的储量信息,验证了基于地质统计学计算储量结果更为接近实际勘探储量,这对于矿山的数字化动态管理,矿山开采具有指导意义。
Abstract:
The goaf is the stope,chamber,etc,left by the excavation in the process of solid mineral exploitation.The cataloging of the goaf reserves is the basic requirement for dynamic management of the mine reserves. The accurate calculation results of the reserves can effectively guide the subsequent production of the mines and improve economic efficiency. But at present, most of the mines in China adopt simple geometric calculation method to calculate the reserves of goaf, which can not evaluate the resources and reserves of mines accurately and objectively.In order to estimate the goaf reserves accurately,taking a mining area in Xinjiang as an example. Firstly,the author analyzes the three-dimensional model method for establishment of the goaf, and two ways of the section and middle section method to model the goaf in the estimation of solid mineral reserves. Secondly,the three-dimensional model of orebody and goaf model based on Geostatistics are intersected by Boolean method, and the reserves of goaf are calculated by volume weighting according to the cut-off model.Finally, by comparing the reserve information of the intersection results between the goaf and the section method,it is verified that the calculated reserve based on Geostatistics is closer to the actual exploration reserves,which is of great significance to the digitized dynamic management of mines and the guidance of mining.
