【摘要】：礦產(chǎn)勘查中的三維可視化建模技術(shù)已經(jīng)在國外的礦山勘查、生產(chǎn)中發(fā)揮了巨大作用,但是目前這種三維建模技術(shù)在國內(nèi)的地質(zhì)勘查單位中很少被利用。本文以四川木里縣菜園子金礦為例,綜合研究Surpac軟件在礦山勘查過程中的三維地質(zhì)建模技術(shù),主要研究工作及成果如下:(1)在對收集到的菜園子金礦床資料進行整理和分析的基礎(chǔ)上,建立了菜園子金礦床地質(zhì)數(shù)據(jù)庫,實現(xiàn)了鉆孔信息可視化。(2)運用Surpac三維建模軟件建立起了菜園子金礦礦區(qū)的地表及金礦體的三維實體模型,實現(xiàn)了礦床的三維可視化。三維可視化建模可以完整準確地表達出鉆孔與金礦體的空間位置關(guān)系,為礦山進行科學的生產(chǎn)進度計劃編制提供基礎(chǔ)與依據(jù)。(3)運用地質(zhì)統(tǒng)計學原理對鉆孔樣品數(shù)據(jù)進行了組合分析,根據(jù)組合樣的統(tǒng)計特征,對實驗變異函數(shù)進行了擬合,建立了合理的變異函數(shù)模型,構(gòu)建起了金礦體的塊體模型。(4)以所建立的塊體模型為基礎(chǔ),采用距離冪次反比法對菜園子金礦床Ⅱ礦體的金資源量進行了估算及分布規(guī)律展示。通過Surpac軟件對菜園子金礦床可視化三維模型的建立,礦體的形態(tài)以及儲量分布能夠較為清楚的掌握,這對以后礦山的科學勘查、合理開發(fā)資源及提高礦山經(jīng)濟效益起著非常重要的作用。
[Abstract]:The 3D visual modeling technology in mineral exploration has played a great role in mining exploration and production in foreign countries, but at present, this 3D modeling technology is seldom used in geological exploration units in China. Taking the Caiyuanzi Gold Mine in Muli County, Sichuan Province as an example, this paper comprehensively studies the 3D geological modeling technology of Surpac software in the process of mine exploration. The main research work and results are as follows: (1) based on the collation and analysis of the collected data of the Caiyuanzi gold deposit, a geological database of the Caiyuan gold deposit has been established. The 3D solid model of surface and gold body in Caiyuanzi gold mine area is established by using Surpac software, and the 3D visualization of ore deposit is realized. Three-dimensional visual modeling can completely and accurately express the spatial position relationship between the borehole and the gold ore body. This paper provides the basis and basis for making scientific production schedule plan of mine. It uses the principle of geostatistics to analyze the borehole sample data, and according to the statistical characteristics of the combined sample, the experimental variance function is fitted. A reasonable variation function model is established, and the block model of gold ore body. 4) based on the established block model, the gold resources of the 鈪，
