Downhole high-pressure air hammers for open pit mining
Abstract. The energy upside potential of downhole air hammers is considered. The article presents the constructional diagram of a new air hammer using high compressed air pressure (up to 3 MPa). The experimental testing of the operating cycle of the air hammer is reported. The authors ascertain the air hammer steel requirements Energy consumption is roughly a quarter compared to air, resulting in lower carbon emission and a lower energy bill. In the case of water DTH, the water leaving the drill bit in the hole is at a low velocity and ambient pressure. However, with air DTH, the air leaving the drill bit in the hole is at a high velocity and high pressure.Water Powered Percussive Downhole Hammers—Energy Savings

Improvement of Down-the-Hole Air Hammer Efficiency by
Design development of down-the-hole (DTH) air hammers is discussed with the aim of increasing efficiency of rock drilling. The problem is solved by making hammering piston with curvilinear frees surfaces which are in no contact with the hammer body. This ensures generation of rock-breaking impact at the minimum energy input. New designs A study by Xtega reported a reduction in the cost of drilling function by 7.5% when using DTH hammers. Therefore, using DTH hammers can lead to improved drilling performance, reduced downtime, and cost savings in drilling operations. Views: 870. Most DTH hammers sizes are in-stock for immediate shipment.Down the Hole (DTH) Hammers America West Drilling Supply
