摘要
介绍空气反循环钻进工艺用于物探爆破孔快速钻进成孔的特点及取得的效果。空气反循环钻进工艺用于沙漠及砾石地层物探爆破孔钻进成孔不仅效率高 。
Features and acquired results are introduced of reversed air circulation drilling technique applied in geophysical hole blasting for a rapid drilling and hole completion. The technique is proved to be effective in desert area and gravel strata, and has advantages of satifying deep to relatively deep hole drilling and completion, and accurate data collection.
