【摘要】 由于煤矿开采条件的复杂度增加,钻井、测井等原始资料匮乏,那些利用原始资料获取信息研究煤层顶板工程地质分区的方法出现了很大的局限性。为了准确、详细地研究原始资料不充足井田的煤层顶板工程地质特征及其分布,在综合钻探、测井等资料的基础上,提出以波阻抗反演技术为辅助手段,应用于巨野煤田龙固井田3煤层顶板,详细研究了煤层顶板岩性分布特点并对其分布进行预测,预测结果与实际结果相符合,有效地证明了在钻井等原始资料缺乏的井田中运用地震反演技术对煤层顶板工程地质分区是有效可行的,解决了由于原始资料缺乏而难以准确预测的问题。更多还原

【Abstract】 In order to research the geological characteristics and its structure of seam roof in the studied region of coalmine correctly and in detail and based on the complex study data of drilling and logging,etc.,the paper proposes the supplementary means of wave impedance inversion technology and it is applied to study the roof lithology distribution characteristics of Seam 3 in Longgu Mine of Juye Coalfield in detail and its distribution is predicted.It can be found that the predicted result accords with the practical outcome.So,it is proved that earthquake inversion technique has some effective and practical values in the study of the geological zoning of seam roofs.更多还原
