山东煤田地震勘探及展望

SEISMIC PROSPECTING AND FORECAST FOR COALFIELDS IN SHANDONG

摘要:

本文简要地回顾了山东煤田地震勘探卅年的历程。总结了煤田地震勘探在煤田构造勘探和岩性勘探中所能承担的地质任务。通过实例说明了在隐伏煤田勘探中采用地震先行引导钻探施工,配合测并的多手段综合勘探方法是提高勘探精度、节省钻探工程量、加快勘探速度的有效方法,且具有明显的经济效益。文章还针对煤矿建设的需要,提出要搞好高分辨地震勘探,提高构造勘探精度,深入进行用地震研究煤层厚度,建立一套适合煤田地震勘探系统和加强以往物探资料的综合解释,更有效地发挥物探在找煤工作中的作用等设想。

Abstract:

In this paper the history of the seismic prospecting for coal in Shandong in the past thirty years is reviewed, and the geological tasks undertaken by coal seismic prospecting in the investigation of the structures and lithological characters of the coalfields are summarized. A comprehensive program followed by drilling and combined with the logging seismic prospecting has been demonstrated by examples to be an efficient and economical approach in the coal prospecting for improving accuracy, reducing the am...
