三维地震勘探

东华理工学院毕业论文（设计）目录摘要本文是介绍在山西省屯留县郭庄煤矿进行三维地震勘探的工程设计。本次三维地震勘探的目的是了解和掌握郭庄煤矿矿区的地质构造、煤层的赋存形态和断层、褶曲、陷落柱发育特征，查明工作区内3#煤层的底板起伏形态、采空区范围、无煤区和煤层冲刷变薄区。本次野外三维数据采集的基本观测系统为8线8炮制束状规则观测系统。通过三维地震勘探获得工区地表面以下的信息数字化成果，为矿区后继生产、优化矿井采掘设计方案、提高生产效率提供详实的基础地质资料。关键字：三维地震勘探;工程设计;断层;褶曲;陷落柱;观测系统SummaryThisAbstractintroducestheengineeringdesignthatthethree-dimensionalearthquakeexploredwillbecarriedoninthecollieryoftheGuo'sofTunliucountyofShanxi.Thethree-dimensionalpurposethatearthquakeexploretounderstandandknowGuovillagegeologicalstructure,toisitdepositshape,faultandpleatsong,subsidethedevelopmentcharacteristicoftheposttocomposecoalseam,collieryofminingarea,findouttheundulatingshapeofbaseplateofcoalseamNo.3intheworkspace,quarrytheemptydistrictrange,therearenocoaldistrictandcoalseamtoerodeandturnintothethindistrict.Fieldthisthree-dimensionalbasicobservationsystemthatdatagatherconcoctfor8Line8bunchesofformruleobservethesystem.Explorepersonwhoobtainworkareasurfacefollowinginformationdigitizedachievementthroughthree-dimensionalearthquake,isitproduce,optimizeminenottoexcavatedesignplan,raiseforminingareaproductionefficiencyofferfullandaccuratefoundationgeologicalmaterialstocarryon.Keyword：Thethree-dimensionalseismicsurveyl;Engineeringdesign;Fault;Pleatsong;Subsidethepost;Observethesystem东华理工学院毕业论文（设计）目录目录1.前言..............................................11.1目的与任务............................................11.1.1项目来源.....................................................11.1.2任务.........................................................11.1.3工作时间.....................................................11.1.4项目要求及依据...............................................21.2工作区范围、交通位置及自然地理环境....................21.2.1工作区范围和交通位置.........................................21.2.2自然地理.....................................................21.2.3气候状况和经济状况...........................................32.地质概况及地球物理特征............................42.1工作区地质及物化研究程度..............................42.1.1以往工作程度成果.............................................42.1.2野外踏勘成果.................................................42.2区域地质概况..........................................42.2.1工作区地层特征...............................................42.2.2工作区构造特征...............................................52.2.3工作区煤层特征...............................................52.2.4勘探区煤质特征...............................................52.3区域地球物理特征......................................62.3.1表层地震地质条件.............................................62.3.2浅层地震地质条件.............................................62.3.3深部地震地质条件.............................................63.野外工作方法及技术要求............................73.1工作方法..............................................73.1.1三维地震试验工作.............................................73.1.2低速带调查工作...............................................73.1.3三维地震勘探观测系统参数的选定...............................73.1.4三维线束的布置...............................................83.2测地工作..............................................83.2.1测量作业采用系统.............................................83.2.2测量仪器及测量方法...........................................93.2.3控制测量和定线测量...........................................93.2.4测量成果....................................................10东华理工学院毕业论文（设计）目录3.3技术要求.............................................103.3.1野外数据采集要求............................................103.3.2测量要求....................................................103.3.3质量目标....................................................104资料整理及报告编写................................114.1主要数据处理方法与技术...............................114.1.1预处理......................................................114.1.2初至波折射静校正............................................114.1.3反褶积......................................................114.1.4速度分析....................................................114.1.5DMO迭加及迭后一步法偏移....................................124.2资料解释.............................................124.2.1解释流程....................................................124.2.2解释的主要资料及要求........................................124.2.3速度标定与时深转换..........................................134.4图件编制方法.........................................134.5报告编写.............................................134.5.1报告的要求..................................................134.5.2报告的内容..................................................145.人员编制和管理...................................155.1项目组人员编制及分工.................................155.1.1项目经理及其岗位职责........................................155.1.2项目技术负责及其岗位职责....................................155.1.3炮班班长及其岗位职责........................................155.1.4爆破员及其岗位职责..........................................155.1.5爆破品保管及其职责..........................................165.2.1组织措施....................................................165.2.2质量保证....................................................165.2.3安全生产管理措施............................................175.3HSE管理.............................................185,3,1内容、标准及组织............................................185.3.
