Brief Introduction of Drill Tail

2022-08-10

The drill tail can be mainly used for mining enterprise operations, the selection of high-quality alloy steel materials as a raw material, after the whole system carburizing treatment. The commonly used drill tail has three types: the drill shoulder (flange) type, the drill lug (lug) type and the spline type.


Hot spot of the week! What are the major global mining events this week?(7.31-8.6)

CCTV news on August 1, the the People's Republic of China Futures and Derivatives Law came into effect on August 1. The law makes up for the legal "short board" in the field of futures and derivatives in China. The biggest bright spot and breakthrough is to bring derivatives trading into the scope of legal adjustment, and establish the three major functions of "price discovery, risk management and resource allocation", which has boosted the confidence of market participants and attracted more hedgers and institutional investors to participate. In addition, the implementation of the the People's Republic of China Futures and Derivatives Act provides a more powerful tool and grip for futures to serve the real economy.

What are the classification, installation and preparation of DTH drills?

2022-07-28

What are the classification, installation and preparation of DTH drills? There are two kinds of rock drills and drilling rigs. Drilling rigs are divided into open-pit drilling rigs and underground drilling rigs. ① Rock drill: used to drill holes in rocks of medium hardness and above, with a diameter of 20-100mm and a depth of less than 20 meters. According to its power, it can be divided into pneumatic, internal combustion, hydraulic and electric rock drills, of which pneumatic rock drills are the most widely used.


Type of high-pressure down-the-hole drill bit and quality requirements for lubricating oil of drill bit

2022-07-18

There are four main types of end face designs used in high-pressure down-the-hole drills: convex end face, flat end face, concave end face and deep concave central end face. Cemented carbide is mostly used in the common tooth distribution mode of ball teeth, spring teeth or ball teeth and spring teeth. 1, the end face convex type: the drill bit is divided into single boss and double boss end face two forms, the latter is mainly used for larger diameter down-the-hole drill. The convex down-the-hole drill can maintain a high drilling speed when drilling into hard and hard abrasive rocks, but the straightness of the drilling is poor, so it is not suitable for rock drilling projects with high straightness requirements.


Demand Market and Maintenance of DTH Bits

2022-07-08

Where is the demand market and direction of DTH drill bits? With the continuous rise of fuel prices, the operating efficiency of construction machinery has become a very important indicator in engineering projects. The selection of high-efficiency rock drilling machinery requires the configuration of high-quality and efficient rock drilling tools. In order to improve the drilling efficiency of the drilling tool and the service life of the drill bit, the research and development team with a large number of instruments also made some adjustments to the structure of the medium and high pressure down-the-hole drill bit, such as some adjustments to the tooth structure of the column teeth on the end face of the drill bit.

The main mining-related contents are as follows: first, by 2025, the energy efficiency of key products in iron and steel, petrochemical, non-ferrous metals and other industries should reach the international advanced level, and the energy consumption per unit added value of industries above scale will be reduced by 13.5 compared with 2020. Second, we should deeply tap the energy-saving potential of iron and steel, petrochemical, non-ferrous metals and other industries, promote the upgrading of technology and process in an orderly manner, promote the level of energy efficiency, and achieve steady improvement of industry energy efficiency. The third is to accelerate the innovation and upgrading of key materials such as high-performance magnet wire, rare earth permanent magnet, high magnetic induction and low loss cold-rolled silicon steel sheet. Fourth, in accordance with the principle of "gas-based reform" to promote industrial coal-fired natural gas substitution in an orderly manner.
