摘要
///This paper outlines and summarizes the initial application process and effect of the HRC drilling and the experience for placer mineral prospecting in Hainan of China. The successful application of HRC supplies a new and high efficient technology for coring (sampling) drilling in marine geological survey in China and foreign countries.
