Introduction of down the hole drilling tools

Down the hole drilling tools are compressed air driven medium and large-diameter blasthole rock drilling machinery. Because of simple structure, easy use, and easy maintenance, etc. they can replace hydraulic rock drilling rigs in open-pit medium and large-aperture rock drilling projects. And  down the hole drilling tools are mainly composed of drill pipes, dth hammers and dth bits. They have types: low air pressure and high air pressure according to the type of compressed air and drilling rig.

Down the hole drill pipe

Down-the-hole drill pipe is made of drill pipe body and joint components at both ends through friction welding. The quality of dth drill pipe mainly depends on the material of the drill pipe body and joints, the welding quality of the welding area and the heat treatment process of the welding area. The material of drill rod body we use is R780/N80 and 35CrMo for joint components. The drill pipe body is seamless steel pipes. After friction welding, a coarser welding structure will appear in the welding area, and then the heat treatment process can improve and restore its structural properties . The processes is induction heating, compressed air nozzle quenching, and induction heating tempering.

DTH hammers have types: low air pressure and high air pressure. The dth drilling hammer including: the piston, inner cylinder, valve seat, check valve and drill bit accessories,etc. Which installing in a slender outer cylinder. And the general users of dth hammers are quarries, mining plants, geophysical bureaus, highway bureaus, etc.

DTH drill bits also have low air pressure and high air pressure. And Low air pressure dth bits are mainly for small geotechnical projects, small quarries and areas with poor rock drilling conditions. The structure of low air pressure dth bits is relatively simple, the process and technical parameters are not high, and the service life is also low.

High air pressure dth bits are a relatively high-tech drilling tool product. Currently, the market demand for high air pressure down the hole drilling tools is gradually increasing. So, to achieve the purpose of efficient and rapid rock drilling, it is necessary to choose high quality and efficient dth drill bits. In other words,dth drill bits of different structures must be according to different drilling methods and rock types.
