Cutting pick is one of the most consumed accessories in mining equipment, and improving its service life is of great significance to improving mining efficiency.
The working environment of cutting pick leads to different failure modes. Analyzing the failure reasons and improving them will help reduce construction costs.
The advantages of button bit have some requirements in production, which are reflected in the selection of materials, equipment, processing accuracy and production technology.
The production process of the hollow steel is the main cause of the surface and inner hole defects of the drill rod.
Early failure of extension rod will reduce the rock drilling efficiency, and its service life can be improved by starting with raw materials and other factors.
DTH eccentric casing drilling technology can effectively avoid cavity collapse, and is widely used in geological disaster protection, etc.
The continuous maturity of the friction welding process makes it more and more widely used in the processing of drill rods.
Early failure of light shank rods can affect the progress of the project, and there are some ways we can prevent it.
The early abnormal failure of the drill rod will increase the construction cost, so what is the cause of the failure of the light shank rod?
Whether the large-diameter DTH drill can replace the roller cone drill should be analyzed technically and economically according to the actual drilling situation.
If more attention is not paid in the process of using MF rods, it will lead to premature failure, which is not conducive to the development of the project.
Casing system to bring the casing into the hole wall can effectively prevent the hole wall from collapsing or quicksand filling the borehole.
In order to obtain higher rock drilling speed and lower perforation cost, it is very important to choose a suitable drill bit and use it reasonably.
Self-drilling anchor bolt has the characteristics of high efficiency, reliability and convenient construction. So it has broad application prospects.
The premise of choosing a down-the-hole hammer is to understand its type and working parameters, and choose according to various factors.
