The air reverse circulation continuous sampling technology has been widely recognized and used in China and rest of the world, called a technological revolution after wire llne coring. The Sweden atlas L8^25 unroofed reverse circulation continuous sampling rig, adopted by the China Golden Group Inner Mongolia Mining Co. Ltd, can not only achieve retractable continuous sampling and classified function, but also detect anomalous conditions of drill-hole depth, speed, hole drilling pressure, and fuselage, realizing real-time monitoring of person, machine integration of an intelligent drilling mode. This drilling mode helps to delineate the orebody boundary, cutoff grade, and is favorable for reasonable mining and ore matching in the Wunuge- tushan copper-molybdenum mine. It makes the mineral resources be reasonably exploited and utilized, thus reducing production cost and improving the overall economic efficiency.
