地表严重缺水的石灰岩山区应用地面炸药震源的尝试

THE POSSIBILITY OF THE UTILIZATION OF SURFACE SOURCE IN WATERLESS LIMESTONE MOUNTAINOUS REGIONS

在地表严重缺水的碳酸盐岩出露山区进行多次覆盖工作,面临着大量炮井无法钻进这一带有普遍性的问题。本文将南盘江拗陷的罗平构造上同一测线的井中放炮和地面放炮获得的地震资料,经过不同计算机的多种方式处理得出的剖面进行对比分析,阐述了目前在缺水山区地震工作中使用地面炸药震源的现实意义。

It is extremly difficult to make the shot-hole drilling in waterless limestone mountainous regions. And if we could get good results bythe author has made a comparison between two sections obtained by surface source and well shooting at the same profile. After an all-round examination, he found that the utilization of surface source in waterless limestone mountainous regions is of practical significance as long as we make the use of surface source in a proper way.
