【正文】 摘 要本設(shè)計(jì)的主要目的是介紹神龍礦區(qū)立井井筒設(shè)計(jì)和施工組織方案設(shè)計(jì)。設(shè)計(jì)內(nèi)容一共分為五章，分別為：第一章主要介紹國(guó)內(nèi)立井井筒施工的發(fā)展歷程，包括：設(shè)計(jì)理念的形成、實(shí)踐，在我國(guó)的引進(jìn)發(fā)展，和對(duì)更深層次設(shè)計(jì)思想的探索等。第二章主要介紹神龍礦的工程概況，水文地質(zhì)概況，和主井的主要技術(shù)參數(shù)，為而后的設(shè)計(jì)提供必要的數(shù)據(jù)儲(chǔ)備。第三章是立井的井壁設(shè)計(jì)，主要包括：設(shè)計(jì)依據(jù)，井壁結(jié)構(gòu)的選擇，井壁荷載，井壁厚度的設(shè)計(jì)計(jì)算，可縮裝置的設(shè)計(jì)計(jì)算，配筋計(jì)算等。凍結(jié)壁厚度的計(jì)算，采用多姆克強(qiáng)度理論和經(jīng)驗(yàn)公式計(jì)算結(jié)果的平均值，來比較得到。凍結(jié)壁平均溫度的計(jì)算,由于巖體平均溫度計(jì)算公式是適用在單排管凍結(jié)下的，而實(shí)際主井的凍結(jié)方案是三排管的差異凍結(jié)，因此最后的計(jì)算平均溫度與實(shí)際設(shè)計(jì)平均溫度有出入。第四章是井筒的強(qiáng)度驗(yàn)算，主要包括內(nèi)外壁的強(qiáng)度驗(yàn)算和配筋驗(yàn)算。第五章是總結(jié)，包括畢設(shè)設(shè)計(jì)和致謝。關(guān)鍵詞：立井；施工；井壁；方案設(shè)計(jì) AbstractSummary of the main purpose of the project is to introduce the shenlong mine shaft design and construction organization design. Design content is divided into five chapters in total, are as follows: Chapter I focuses on mine shaft construction in China39。s development process, including: design concept formation, practice, introduction of development in China, and for deeper exploration of design ideas. Chapter II focuses on project overview of the shenlong mine, hydrological and geological survey, and main technical parameters, and designed to provide the necessary data of the reserve. Chapter III is the design of shaft lining, including: design considerations, selection of shaft lining structure and wall loads, design and calculation of wall thickness, shrinking device design, reinforcement calculation, and so on. Calculation of thickness of frozen wall, with Sam gram strength theory and empirical formula calculation results, on average, to be. Calculation of average temperature of frozen wall, due to the average temperature of rock formula is applicable under the single pipe freezing, but the actual difference programme is three main shaft freezing pipe freezing, so the final calculation of average temperature and average temperature different from actual design. The fourth chapter is a strength check of the shaft, including intensity checking putation and reinforcement calculation of the inner and outer walls. The fifth chapter is summarized, including set design, and thanks.Keywords: Vertical shaft；Construction；Shaft lining；Sheme design 目錄摘 要 IAbstract II引言 1第一章 概述 1 我國(guó)建井發(fā)展概況 1 國(guó)外凍結(jié)法鑿井的研究現(xiàn)狀 3 我國(guó)凍結(jié)法立井施工技術(shù)發(fā)展歷程 4 深井施工需要研究的幾個(gè)課題 6 深井支護(hù)技術(shù) 6 通風(fēng)降溫技術(shù) 6 防水、治水技術(shù) 7 施工工藝與裝備技術(shù) 7 深厚沖積層凍結(jié)鑿井技術(shù)現(xiàn)狀及存在問題 7 凍結(jié)壁的計(jì)算 7 凍結(jié)溫度的計(jì)算 8 凍土抗壓強(qiáng)度試驗(yàn) 8 凍結(jié)壁變形 9 外圈孔外側(cè)凍結(jié)壁擴(kuò)展范圍 9 其它方面的問題 9第二章 趙固二礦主井設(shè)計(jì)概況 11 礦區(qū)概述及地質(zhì)特征 11 礦區(qū)概述 11 地質(zhì)構(gòu)造 1
