Drilling is one of the main technical means for mineral exploration, and the quality of drill holes is of great significance to the resource evaluation and mine design. This paper reviews the history of the development of drilling quality assessment standards by various geological exploration departments, and by comparing the application status of the drilling quality classification standards, it raises some issues below: the existing drilling quality evaluation standards are not unified, different specifications are not compatible, the quality assessment document formats are not unified, and the ecological and environmental protection is lenient. It then presents the index evaluation system and main characteristics of the provincial standard of Heilongjiang——Drilling Quality Requirements For Non-coal Solid Minerals. It is proposed that the competent authorities of the industry should organize the formulation of the drilling quality standard as soon as possible.
