  • The Wulong gold deposit is located in the ore-concentrated district of eastern Liaoning Province. It is a large quartz vein type mine hosting more than 80 tons of gold. However, with the increase of mining volume, the mining depth of the deposit is nearly 1 km, and the retained reserves are decreasing. Therefore, it is urgent to carry out deep prospecting research in the mining area. On the basis of previous studies, a high matrix diamond coring bit was developed through the study of bit matrix formula, diamond parameters and bit structure. The field test indicates that the bit effect is remarkable and that the problems of low drilling efficiency and short service life of original bits in this mining area have been solved.
