Discussion on the Diameter of Main Section in Medium-shallow Hole in Diamond Core Drilling for Geological Exploration
Abstract:Analysis was made on the borehole diameter in diamond core drilling for geological exploration. At different angles, such as coring quality meeting the requirement of studying and evaluating geological mineral resources, economic effect of drilling technology and feasibility of drilling method, the author suggested that B size should be applied to main section for medium-shallow hole construction.
