What is Down-the-hole Eccentric Casing Drilling Technology?
DTH eccentric casing drilling technology can effectively avoid cavity collapse, and is widely used in geological disaster protection, etc.
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.
There are many kinds of down-the-hole drill bits, how to choose the right product is very important for every user.
To prevent early failure of deep hole and large diameter DTH drill bits, it is inseparable from its material selection and heat treatment process.
The shape of the end face is directly related to the rock drilling efficiency and service life of DTH drill bit. Commonly used mainly five.
There are many benefits for manufacturers to analyze the reasons for the failure of high-pressure DTH drill bits, so what are the reasons?
The identification of steel for rock drilling tools is of great significance, and the main identification methods are spark and fracture identification.
