As the main means of geology and mineral exploration, drilling engineering provides an important guarantee for revealing underground geology and mineral information by underground drilling. What exactly is a drilling project? How does it play a role in exploring the underworld?

Geological prospecting underground drilling
Diamond-shaped underground drilling
Drill bit - the "diamond" that cuts through the ground
The cobalt machine is designed and produced for the Ministry of Geology and Mineral Resources, mainly for geological prospecting work. In the past, there were only 100m tunnel varieties. In recent years, starting from Dukan 150 type, it has been extended to 75m and 30m type downward and is developing 300m type upward to form a series gradually. Geological prospecting underground drilling is not simply pursuing portability, the main caliber will be based on 59mm to meet the needs of geological prospecting.It has the characteristics of a large underground drilling diameter (opening hole 90mm) and strong pressure capacity (maximum 2T) to make up for the deficiency of similar tunnel underground drilling RIGS. The double-column of the fixed rig is also changed into hydraulic cylinder support, which is very convenient to operate. The pillar and the guide rail frame of the rig are connected through the Angle changer, which can underground drilling holes at various angles.
It is a series of underground drilling equipment designed for metallurgical and non-ferrous systems to adapt to mine development. It is named Diamond-100 underground drilling machine, which is a mechanical powerhead underground drilling machine powered by compressed air, and adopts a sliding pyrolyzer and oil cylinder to pull the underground drilling tool structure. All the working procedures of the underground drilling machine except the rotation are controlled by the hydraulic torsion system. The design embodies the principle of "multi-purpose", such as lifting and adding and reducing pressure devices into one.
A drill bit is an important tool for directly breaking rock and creating boreholes. To speed up drilling, it is necessary to use a "sharp" bit that is suitable for the formation conditions. Common drill bits are scraper bits, tooth wheel bits, natural diamond bits, and PDC bits of different structures and specifications. Various drill bits have different characteristics, and the most used bits at present are dental wheel bits and PDC bits. PDC bits: The drilling principle is the same as that of scraper bits, both are cutting-type bits. Its cutting edge is made of synthetic diamond and sintered tungsten carbide, which has better strength performance than scraper bits. Diamond drill bit: Its cutting edge is made of natural diamond. The larger the particles of natural diamond, the greater the hardness. Tooth wheel drill bit: It achieves rock breaking by crushing, impacting, and shearing the rock when underground drilling works.
It is the responsibility of each manufacturer to produce underground drilling that meets the standards Hambition mining conducts many tests on underground drillings for connection before they leave the factory, and the quality qualification rate is guaranteed.
