金屬礦采空區(qū)三維探測及可視化建模與應(yīng)用
摘要: 準確掌握采空區(qū)形態(tài)、大小及其邊界是控制因采空區(qū)引發(fā)的災(zāi)害及優(yōu)化采礦設(shè)計等的重要基礎(chǔ)性工作.運用空區(qū)三維激光探測系統(tǒng)對采空區(qū)進行精密探測,獲取探測數(shù)據(jù),對原始數(shù)據(jù)處理后,運用三維建模軟件Surpac精確構(gòu)建復(fù)雜空區(qū)三維可視化模型,直觀地表達空區(qū)的空間形態(tài);以空區(qū)三維模型為基礎(chǔ),進行空區(qū)的體積、頂板面積和采場周邊的超、欠挖量、存留礦量、采場塌陷區(qū)回采指標的計算及動態(tài)監(jiān)測,并準確獲得了采空區(qū)的實際邊界等相關(guān)信息,從而為礦山進一步開展礦柱爆破設(shè)計、空區(qū)充填、貧損測定與控制,以及進行采場垮塌區(qū)處理等提供可靠的基礎(chǔ)性依據(jù). Abstract: Accurate knowledge of a disastrous cavity's shape,size and boundary is an important basic for controlling cavity collapse and optimizing mine design.With the results of precise detection of a complicated cavity by 3 D Cavity Monitoring System,3D visual model of the cavity was built by Surpac.On the basis of the 3D model,the thesis calculated the cavity volume,roofs area,volume of over-excavation,under-excavation around the cavity,retention ore mining index.A dynamic monitoring of stope subsidence was conducted and got accurate information of borderline and sections,providing the reliable data for blasting design,filling design,ore dilution control and stope subsidence treatment. 作 者: 王國燾 羅周全 劉曉明 朱青凌 WANG Guo-tao LUO Zhou-quan LIU Xiao-ming ZHU Qing-ling 作者單位: 中南大學(xué)資源與安全工程學(xué)院,湖南長沙,410083 期 刊: 中國地質(zhì)災(zāi)害與防治學(xué)報 Journal: THE CHINESE JOURNAL OF GEOLOGICAL HAZARD AND CONTROL 年,卷(期): 2010, 21(1) 分類號: X936 P694 關(guān)鍵詞: 采空區(qū) CMS Surpac 可視化 三維建模 Keywords: cavity CMS surpac visualization 3D modeling【金屬礦采空區(qū)三維探測及可視化建模與應(yīng)用】相關(guān)文章:
