摘要
通过介绍兖州、淮南等11个矿区20多个煤矿采区三维地震成果,对各矿探采对比情况进行统计与分析,总结出影响三维地震勘探成果精度的5个技术问题,并指出造成这些问题的3个主要原因,即:野外施工质量普遍下降;方法研究工作严重滞后;三维地震资料二维解释仍很普遍。为提高采区三维地震勘探成果精度提出了6点建议,即:推广高密度三维地震技术,解决精细探查问题;围绕共性关键问题,开展攻关研究与示范应用;发挥产学研结合优势,挖掘现有技术的潜力;加强地震行业自律,施行市场准入制度;集中优势技术力量,加强基础理论研究以及开展煤矿井下地震技术研发,提高地质保障水平。
Through introduction to 3D seismic prospecting results of 11 mining areas,20 more coalmines in Yanzhou and Huainan areas,carried out statistics and analysis of correlations of prospecting and mining information.Summed up 5 technical issues impact 3D seismic prospecting result precision,and pointed out 3 main causations,namely： generally downgraded field operation quality;seriously lagged methodology research;generalized 3D seismic data 2D interpretation.To improve winning district 3D seismic prospecting result precision,6 suggestions put forward： generalize high density 3D seismic technology,to settle the fine prospecting issue;aim at common key problems,to carry out scientific research and tackle the key research project and demonstrating application;full play to integrated production,teaching and research predominance,to dig out existing technical potential;strengthen seismic prospecting industrial self-discipline,to put in force of entry certification system;concentrate preponderant technical forces,to strengthen fundamental research and coalmine underground seismic technical research and development,improve geological security level.
