Micromine软件在河南石寺——北冶铝土矿床三维建模和资源量估算中的应用与探讨

Micromine的出现提升了矿山信息数字化管理水平,提高了地质工作中数据利用效率。通过查阅资料发现,关于Micromine在沉积型矿床中的应用报道微乎其微,石寺—北冶铝土矿位于河南省主要铝土矿成矿带上,属沉积型矿床。利用Micromine系统对I号铝土矿矿体进行三维建模,并建立三维矿块模型。采用距离幂次反比加权法对矿块模型进行推估,最终得到总资源量17 630万t,与传统块段法16 895万t相比增加4. 35%; Al_2O_3总量10 101万t,与传统块段法9890万t相比增加2. 14%。两者计算结果十分接近,体现Micromine软件在沉积型矿产中的实用性。

Disscussion on application of micromine software in the 3D modeling and resources estimation of Shisi-Beiye bauxite deposits, Henan

The emergence of Micromine has improved the level of digital management of mine information and improved the efficiency of data utilization in geological work.The author found that the application of Micromine in sedimentary deposits has been reported very little.The Shisi-Beiye bauxite deposit, located in the main bauxite metallogenic belt in Henan Province, belongs to a sedimentary deposit. Using Micromine system, the 3D model for I bauxite orebody was carried out and a 3D block model has been established. The total amount of resources 176 300 000 tons was estimated by using the distance power inverse weighted method in the block model. The resources increased by 4.35% comparing to 168 950 000 tons estimated by the traditional block method, and the Al₂O₃ increased by 2.14% to 101 010 000 tons from 98900000 tons in traditional block method. The calculated results are very close and reflect the practicability of using Micromine software in sedimentary minerals resources estimation.
