| Abstract:A new combination of core drilling with casing and downhole hammer technology is discussed in this paper, which is designed for the characteristics of overburden drilling combining with the new requirements of environmental protection for geological exploration. In consideration of economic and environmental impacts of drilling projects, this technology is centered on downhole hammer drilling, which can provide a new solution for the problem of low drilling efficiency and poor quality. |
