【摘要】：隨著計(jì)算機(jī)的升級(jí)和三維可視化技術(shù)的快速發(fā)展,以及“數(shù)字礦山”概念普及推廣,礦山三維可視化建模技術(shù)受到了普遍重視,礦山三維可視化建模技術(shù)應(yīng)用已成為實(shí)現(xiàn)礦山企業(yè)安全高效生產(chǎn)和科學(xué)管理的有力舉措。本文基于Surpac礦業(yè)工程軟件,在收集整理了三道灣子金礦地質(zhì)資料基礎(chǔ)上,研究并構(gòu)建了三道灣子金礦鉆孔數(shù)據(jù)庫(kù)、地表模型、實(shí)體模型、巷道模型和塊體模型等,并對(duì)三道灣子金礦三維可視化建模技術(shù)開展了應(yīng)用研究。本文研究的主要工作和獲取到的成果如下:1、收集并且整理了三道灣子金礦采場(chǎng)的原始數(shù)據(jù)資料,包括采場(chǎng)范圍內(nèi)地理、地質(zhì)概況,礦區(qū)礦床特征等,加工處理了采場(chǎng)內(nèi)各個(gè)勘探面的紙圖與原始CAD電子圖件,通過重建與優(yōu)化處理,為采場(chǎng)的模型建立打下了基礎(chǔ)。2、分析研究了三道灣子金礦區(qū)的地表情況、鉆孔資料和實(shí)際開采情況,創(chuàng)建了三道灣子地質(zhì)數(shù)據(jù)表,主要包括collar(鉆孔開口信息表)、survery(鉆孔測(cè)斜信息表)、巖性表(鉆孔各分段地質(zhì)巖性信息表)和化驗(yàn)表(鉆孔各分段的采樣品位表)四個(gè)數(shù)據(jù)表。結(jié)合Surpac軟件,提出了三維地質(zhì)建模的方法和流程,建立了三道灣子金礦采場(chǎng)范圍內(nèi)的鉆孔數(shù)據(jù)庫(kù),研究了鉆孔數(shù)據(jù)庫(kù)的三維可視化顯示,從而形象直觀獲取金等元素的空間品位分布和變化規(guī)律情況。3、以Surpac軟件為工具,創(chuàng)建了三道灣子金礦的地表模型、實(shí)體模型和巷道模型。在地表方面,利用等高線方法構(gòu)建了三道灣子金礦的地表模型。在礦體方面,通過分析和研究實(shí)體模型的建模方法和流程,構(gòu)建了三道灣子金礦實(shí)體模型等。通過實(shí)體模型的建立,可以形象直觀的了解三道灣子金礦的各個(gè)礦體的幾何分布情況,為三道灣子金礦進(jìn)行生產(chǎn)計(jì)劃和管理提供了科學(xué)依據(jù)。4、運(yùn)用Surpac軟件創(chuàng)建了三道灣子金礦的塊體模型,對(duì)塊體模型進(jìn)行賦值,除直接賦值外,更重要是采用距離冪次反比法進(jìn)行品位插值,并按照約束條件進(jìn)行品位屬性顯示等。通過創(chuàng)建塊體模型也為三道灣子金礦進(jìn)行儲(chǔ)量估算創(chuàng)造了條件。三道灣子金礦三維可視化模型創(chuàng)建后,礦體的形態(tài)以及品位的分布能夠較為清楚的掌握,這對(duì)三道灣子金礦合理的采礦設(shè)計(jì)、開發(fā)資源、提高礦山經(jīng)濟(jì)效益都起到了非常重要的作用,也對(duì)其他金屬礦山的三維可視化建設(shè)起到了示范帶動(dòng)作用。
[Abstract]:With the upgrading of computer and the rapid development of 3D visualization technology, and the popularization of the concept of "digital mine", 3D visualization modeling technology of mine has been paid more and more attention. The application of 3D visualization modeling technology has become a powerful measure to realize safe and efficient production and scientific management of mine enterprises. Based on the Surpac mining engineering software, based on the geological data of Sandaowanzi Gold Mine, this paper studies and constructs the drilling database, surface model, solid model, roadway model and block model of Sandaowanzi Gold Mine. The 3D visual modeling technology of Sandaowanzi Gold Mine is studied. The main work and results obtained in this paper are as follows: 1. The original data of Sandaowanzi gold mining stope are collected and sorted out, including stope geography, geological profile, ore deposit characteristics, etc. The paper map and the original CAD electronic map of each exploration surface in the mining site were processed and processed. Through reconstruction and optimization treatment, the foundation of the model building of the stope was laid, and the surface condition of the Sandaowanzi gold mining area was analyzed and studied. Borehole data and actual mining conditions have created the Sandaowanzi geological data sheet, It mainly includes four data tables: borehole opening information table, lithology table (borehole sublevel geological lithology information table) and laboratory test table (borehole sampling grade table). Combined with Surpac software, the method and flow of 3D geological modeling are put forward, the borehole database in the stope of Sandaowanzi Gold Mine is established, and the 3D visualization of borehole database is studied. Thus, the spatial grade distribution and variation law of gold and other elements are obtained visually. The surface model, solid model and roadway model of Sandaowanzi Gold Mine are established with Surpac software as a tool. On the surface, the surface model of Sandaowanzi Gold Mine is constructed by contour method. In ore body, the solid model of Sandaowanzi Gold Mine is constructed by analyzing and studying the modeling method and flow of entity model. Through the establishment of solid model, the geometric distribution of each orebody in Sandaowanzi Gold Mine can be visualized and intuitively understood. This paper provides a scientific basis for the production planning and management of Sandaowanzi Gold Mine. Using Surpac software, the block model of Sandaowanzi Gold Mine is created, and the block model is assigned, except for the direct assignment. It is more important to use the distance power inverse ratio method to interpolate the grade and display the grade attribute according to the constraint conditions. The establishment of block model also creates conditions for reserve estimation of Sandaowanzi gold deposit. After the 3D visualization model of Sandaowanzi gold deposit is established, the shape and grade distribution of ore body can be clearly grasped, which is reasonable for the mining design and exploitation resources of Sandaowanzi gold mine. The improvement of mine economic benefits has played a very important role in the construction of 3D visualization of other metal mines.
