摘　　要：别列瓦尔矿区位于塔吉克斯坦苦盏市东北部,距离杜尚别约400 km。矿区内的矿体及岩体断裂破碎带发育(Ⅳ/Ⅴ类岩体,RQD值为0%~50%)。阐述了利用Micromine三维制图软件、依据三维建模及矿体空间展布品位估值的原理,采用钻孔RQD值替换矿体品位值对别列瓦尔矿区进行了RQD三维地质建模,模拟矿区矿体及岩体破碎带的空间展布形态,为矿区生产建设提供完整直观模型的过程,其具有直观易用的作用:清晰显示了破碎带与矿体空间形态之间的关系,根据三维模型能够明确+950~+900 m标高段适宜作为首采地段。The Beleval mining area is located in the northeast of Khujand City,about 400 km away from Dushanbe.The ore bodies and rock mass fractures and fracture zones in the mining area are developed(class IV/V rock mass,RQD value 0%~50%).This paper uses Micromine 3D mapping software,replaces the ore body grade values with the drilling RQD values based on the principles of 3D modeling and ore body spatial distribution grade evaluation,and conducts RQD 3D geological modeling of the Belevar mining area,simulates the spatial distribution form of the ore bodies and rock mass fracture zones in the mining area and provides a complete and intuitive model for the production and construction of the mining area,which is intuitive and easy to use:The spatial morphological relationship between the fracture zones and the ore bodies is clearly displayed,and according to the 3D model,it can be determined that the+950~+900 m elevation is suitable as the first mining area.
