贵州省道坨超大型锰矿床精细全息三维地质建模研究

摘要

贵州省道坨超大型锰矿床属于"大塘坡式"锰矿床,具有世界上独特的成矿环境和机制,本文研究综合应用道坨超大型锰矿详实勘探资料,构建高精度全要素三维地质模型的方法.建立了道坨超大型锰矿床地上-地下一体化三维模型,包含着丰富的地质属性信息和更为精细的地质空间信息,形象地表达了矿体的三维空间分布状况、矿体与围岩之间的叠覆关系、燕山期形成的典型"W"型铲式重力滑脱构造的空间形态,以及该重力滑脱构造系统对地层及矿体的交切关系,直观表达了该矿床的成矿机制、赋存状况和分布规律.%The Daotuo superlarge manganese deposit in Guizhou Province belongs to the'Datangpo type' manganese deposit,which has a unique ore-forming environment and mechanism in the world. In this paper,it studies the comprehensive application of the detailed exploration data of the Daotuo superlarge manganese ore and constructs the method of high-precision 3D geological model. A 3D model of ground to underground integration of the Daotuo superlarge manganese deposit is established,which contains rich geological property information and finer geological space information,which expresses the three-dimensional spatial distribution of the ore bodies, the overlapping relationship between ore bodies and wall rock, the spatial form of the typical"W" shovel-type gravity slippage structure formed by the Yanshan period,and the intersection relationship between the gravity slippage tectonic system to the stratum and ore bodies, intuitive expressed the mineralization mechanism of the deposit, status of occurrence and distributing regulation.
