摘要:

三维地质模型的精细描述是相关三维成矿预测和储量估算的前提和保证,更有利于发挥计算机三维可视化技术和地质统计学等在工程建设领域的作用。以河南省某铝土矿床为例,针对三维地质建模过程中存在的难点问题,在传统建模方法基础上提出了一种基于勘探工程实际空间位置建模方法,在野外勘探工程密度较小的情况下也能准确圈定矿体。首先以地质勘查资料为基础,对建模的过程进行了阐述,构建了三维矿体模型、三维地层模型,然后采用普通克里格法和距离幂次反比法估算了资源储量,并对矿体的品位分布和储量类别进行了表达,最后使用3种不同的验证方法进行了精度检验。实现了资源量类别、资源量品位区间、资源量估算动态可视化管理。通过对该矿区的矿体建模和资源量计算,验证了方法的有效性,对于同类型矿床有一定的借鉴意义。

Abstract:

More attentions have been paid to 3D geological modeling by earth science experts and scholars, which gradually becomes a research hotspot in the fields of mine geology, oil and gas exploration, etc. The detailed description of the 3D geological model is the prerequisite and guarantee for metallogenic prediction and reserve estimation,which is more favorable to play an important role in 3D visualization technology and geostatistics. A bauxite deposit in Henan Province was provided as an example and a series of difficult problems were dealt with in the 3D geological modeling. First of all, we used multiple vertical profiles to build ore body contour line. Based on the geological exploration data, the modeling process was discussed. The geometric database raw data format was revised. The auxiliary coil was used to build 3D model. Then, terrain surface model, the 3D ore body model, 3D stratum model and 3D structure model were successfully established. Based on the accurate 3D models, the L1 reserve was estimated by the Distance Power Inverse Ratio method and Ordinary Kriging. Ore bodie distribution and the reserves category were expressed. Finally, three different verification methods were used to verify the accuracy. Based on the traditional modeling method, a method based on the actual spatial location modeling of exploration engineering was improved, which can be modeled by any exploration project location. The accuracy and reliability of modeling were improved. It achieved the goals of the reserves category, reserve grade interval and reserve estimation dynamic visualization. The errors were within the controllable range.

Key words: 3D geological modeling    Ordinary Kriging    Accuracy test.    Inverse distance squared distance power    Reserves category
