到目前为止，国内在花岗岩和片麻岩等硬基岩大片出露地区打井放炮，开展勘探工作尚不多见。常规的钻井方法在这类地区无法保证工期，且成本很高。本文提出的空气潜孔（锤）钻进技术在D工区地震数据采集中取得了令人满意的效果。文中通过常规钻井和空气潜孔钻井的实际对比，充分体现了空气潜孔钻进技术在硬基岩环境出施工的优越性。 Up till now, it is still rare to conduct drilling and blasting in the large-scale hard-rock outburst areas such as granite and gneiss in China. Conventional drilling methods can not guarantee deadlines in such areas and are expensive. The proposed air downhole (hammer) drilling technology has achieved satisfactory results in seismic data acquisition in D Zone. In this paper, the actual comparison of conventional drilling and DTH drilling fully embodies the superiority of air DTH drilling technology in hard rock environment.
