Water Well/Mine/Oil/Gas/Coal Top Drive Rotary Core Down the Hole Borehole Drilling Rig

Features •

Small energy loss: The impact energy is directly transmitted to the drill bit without passing through the drill rod, which reduces the energy loss in the transmission process and improves the energy utilization rate, so that the rock can be broken more effectively.

• Good rock removal effect: The impactor discharges the rock debris at the bottom of the hole by blowing high-pressure gas, which can timely remove the rock powder at the bottom of the hole, avoid the accumulation of rock powder affecting the drilling efficiency, and help to improve the drilling speed.

• High drilling accuracy: Since the impactor is placed at the bottom of the hole and the direction is well positioned, there is generally no inclined hole or bent hole phenomenon, which can ensure the verticality and straightness of the hole and improve the drilling quality.

Application areas •

Mining: widely used in the mining of various mineral resources, such as metal mines such as iron ore, copper mine, gold mine, and non-metallic mines such as coal mine and limestone mine, for drilling blasting holes for ore mining and excavation.

• Geological exploration: In geological exploration, down-the-hole drills can drill and sample underground rocks, helping geologists understand the structure, composition and geological structure of underground rocks, and determine the distribution and reserves of mineral resources.

• Engineering construction: commonly used in urban construction, railways, highways, rivers, hydropower and other projects, drilling rock anchor holes, anchor holes, blasting holes, grouting holes, etc., to provide support for the basic construction of the project.
