Pressure drop characteristics of reverse circulation pneumatic cuttings removal during coal seam drilling

To solve the problems that the borehole depth is shallow and the drilling efficiency is low during the gas drainage drilling in soft coal seam with current cuttings removal method, a new technology of reverse circulation pneumatic cuttings removal is proposed. The working principle of reverse circul...
