Integrated anchor cable drill pipe (thick pier)
Mine air drill pipe Mine bolt drill pipe is based on the innovation and transformation of the wind drill pipe, is the replacement of the wind drill pipe products. It has the characteristics of wear-resistant, fast time-saving and labor-saving, and is more than a hundred times the life of the general air drill pipe, which is economical and practical. Mine bolt drill pipe is a new type of product. It can detect gas and water. It can be used alone or in combination. It can use new drill bits and old drill bits to prevent drill bits from falling off. Light weight, rapid connection, is an essential advanced tool for coal mine water exploration. Connecting the locator air drill pipe Connecting the locator anchor cable drill pipe, with a diameter of 19mm and an overall length of 1000mm, the thread form adopted for the rod body

The characteristics of the cross bit-beneficial mining technology.
The scope of use of cross bit is mainly for rock, in general, it mainly works in limestone, granite, marble. When we choose, we must make corresponding choices according to the environment in which we want to work and the types of rocks, so that its role can be maximized. Although the cross bit looks very small, it is really small and powerful. In many hard, cracked rocks, it can work very well, even in such a working environment, it can also protect itself very well, that is to say, the damage is not big, so its service life is very

How to maintain the spiral drill pipe-beneficial mining technology.
1. The use of spiral drill pipe shall be within the rated drilling distance of the drilling rig. According to the technical parameters of the drilling distance and the drilling rig model, the matching drill pipe shall be selected. 2. When the spiral drill pipe is used with the drill bit, the drill bit should be larger than the diameter of the drill pipe under normal circumstances, and the condition of the drill and the drill pipe should be paid attention to at all times during the drilling process. In case of sticking, locking, etc., stop drilling immediately or drill slowly after returning to ensure that the drill pipe is not bent and deformed. 3. When the spiral drill pipe is ventilated or ventilated, the drill pipe shall be tightly connected during drilling. When the drill pipe has a seal, such as O-ring seal, pay attention to the use of the seal, in the event of damage, corrosion and other phenomena, to replace the seal in time. After the drilling is completed, do maintenance and cleaning work on the seal. 4. The spiral drill pipe should be connected manually and correctly during drilling to ensure close cooperation. It is not possible to use the drilling rig to drill directly to prevent damage to the drill pipe. The drilling depth of the high-efficiency spiral drill pipe shall meet the relevant requirements of geological drilling to prevent the drill pipe from falling off due to the drilling depth reaching the use limit of the drill pipe. 5. If the bending degree of the spiral drill pipe exceeds the standard requirements or the thread damage after use causes the normal operation to be impossible, it shall be scrapped or returned to the factory for repair in time. 6. When working in acid and alkali areas, it is necessary to pay attention to the corrosion of the drill pipe. When drilling is completed, clean the surface of the rod body with clean water in time to remove the corrosion layer. 7, spiral drill pipe should be carried out regular maintenance, according to the use of the environment and air humidity to determine the maintenance cycle, regular anti-rust oil and dust treatment. After derusting/dust cleaning, protective caps shall be buckled or packed and sealed to ensure that the drill pipe is normally new.

How to judge the quality of the drill rod-beneficial mining technology.
The drill rod is a tool for connecting the drill bit and rock drilling in the well and roadway engineering. The drill rods generally used in mine shaft engineering are hexagonal hollow steel and hollow circle steel. The inner diameter of hexagonal hollow steel is 22mm and 25mm, and the outer diameter of hollow circle steel is 32mm and 38mm. The steel rods include finished steel rods and forged steel rods. The finished steel rods are forged according to a certain length and then installed with drill holes. The forged steel rods are cut with hollow hexagonal steel as required, and then the drill ends and forging machines are used to forge. The quality of the drill rod depends on the steel type, heat treatment process, the structural design of the drill rod, the transition between different sections, and even.

Classification of drill pipe joints-Yikuang Technology
A drill pipe is a steel pipe with a threaded tail that is used to connect the surface equipment of the drilling rig to the drilling equipment or bottom hole device at the bottom of the well. The purpose of the drill pipe is to carry drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The drill pipe must be able to withstand huge internal and external pressure, distortion, bending and vibration. Today we mainly come to understand the drill pipe joint, the drill pipe joint is an integral part of the drill pipe, the male joint and the female joint, connected to the two ends of the drill pipe body. In order to enhance the connection strength of the joint, the wall thickness of the pipe body needs to be increased at the joint part. According to the thickening method, it can be divided into: internal thickening, external thickening, internal and external addition

Structure and working principle of rib drill pipe
The structure of the 1. rib drill rod The rib drill rod is mainly composed of two parts: the rod body and the rib piece. On a core tube similar to an outer flat drill pipe, a high-hardness blade with a certain width (generally about 18mm) and a certain height (generally about 7mm) is helically welded, and processed to make its outer diameter consistent with that of the outer flat drill pipe, as shown in fig. 2. Fig. 2 main specifications of rib drill rod: φ 50-φ 63.5, φ 63.5-φ 73, φ 73-φ 89 cases: rib drill rod φ 73-φ 89 refers to the diameter of the drill rod body is φ 73mm, and the outer diameter of the rib piece (I .e. the outer diameter of the drill rod) is φ 89mm. 2. ribs
