Abstract

Abstract

This paper describes the theory, features and testing results of the air reverse circulation drilling process used in geo-physical blast hole drilling. It is concluded through the testing that the process provides high penetration rate, deeper depth and explosive installation without tripping drilling tools; and its application is of good prospect.
