摘要
大型陆相煤盆地边缘的煤层划分与对比是煤炭地质勘查的关键性基础工作。依据基础地质勘探资料,应用标志层法、煤层自身特征法、测井曲线组合法、灰色关联分析法等,对永陇矿区老爷岭普查区延安组煤层进行综合对比。研究结果表明,在成煤环境不稳定地区,应用地质、地球物理和灰色关联分析等方法进行煤层综合对比可以取得可靠的结果。
Coal seams partition and correlation are major elemental tasks of coal geological exploration in the marginal area of large limnic basins. Based on the basic geological data, carry out comprehensive correlation of Yanan Formation coal seams in the Laoyeling prospecting area, Yongshou-Longxian mining area. The result has demonstrated that： using geological, geophysical and gray relational analyses to carry out comprehensive correlation in unstable coal-forming environment areas can obtain dependable results.
