Good effects were received by the application of air reverse circulation continuous sampling technology with rational drilling equipments and drilling parameters in an auriferous conglomerate mine of Jilin. The practice shows that the recovery of rock samples is more than 98% in auriferous conglomerate by the use of air reverse circulation continuous sampling technology, where sampling is difficult; and along with DTH hammer technology, drilling efficiency in hard rocks can be improved with the cost being reduced. The paper introduces the construction equipment, pipe configuration and the process of air reverse circulation continuous sampling technology.
