煤矿采区三维地震探采对比效果的分析与思考

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。

Pondering on Coalmine Winning District 3D Seismic Correlation of Prospecting and Mining Information Effect Analysis

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.
