Experimental Study on Drilling Technology in Molybdenum Mine Mined-out Area

Abstract:

According to the complex geological structure in molybdenum mine of Luanchuan with crisscross underground mined-out areas and uneven mining floor, experimental research was made on drilling equipment integrated various advantages which took reverse circulation DTH hammer drilling technology as the core to solve the exploration difficulties in this mining area. The artificial hole-making, casing guiding, or real time parameter control methods were adopted, the construction was completed with good effects.
