Introduction of the Core Drilling Rigs

March 07 , 2022

Introduction of the Core Drilling Rigs Core drilling rigs are widely used in geological survey exploration, geophysical survey; road and bridge construction survey; geotechnical engineering blasting hole, grouting hole, structural quality inspection of concrete engineering, agricultural water well drilling and other drilling construction. The core drilling rig is mainly composed of power, reducer, water pump, clutch and gearbox, vertical shaft box, winch and drilling tower. The most important thing in operating the core drilling rig is experience and skills. During the construction process, when the drill pipe bit is lowered into the hole, the operation and control are completely determined by the operator's experience and judgment. Although it is not visible how the drilling tools of the core drilling rig perform cutting during construction, the force of the drilling tools in the hole will be fed back to the equipment outside the hole. For example: load, vibration, so the operator can judge the situation in the hole by observing the changes of the equipment outside the hole, so as to change the operation control. The two most commonly used methods in operating core drilling rigs: listening to the sound and watching the drilling speed!

Why the DTH Blasting Drilling need a Dust Collector system?

March 02 , 2022

Why the DTH Blasting Drilling need a Dust Collector system? When the down-the-hole drilling rig operating, it is powered by compressed air. With the increase of air pressure, the drilling speed of the down-the-hole drilling rig is faster; with the increase of dust at the drill pipe, dust is spread around the drilling rig. It will not only endanger the health of operators, but also affect the speed of down-the-hole drilling operations and accelerate the damage to mechanical and electrical equipment. If no effective dust removal measures are taken, it will cause great dust pollution to the mine environment. For operators who work in high-concentration dust environments for a long time, if the protective measures are not effective, it is very likely to lead to serious pneumoconiosis, and even loss of The ability to work has caused great harm to the physical and mental health of workers and their families.

Advantages of the Pneumatic Drilling

February 14 , 2022

Advantages of the Pneumatic Drilling The invention and development of the pneumatic water well drilling rig is a major revolution in drilling technology. It has changed the traditional way of cutting and grinding rock, breaking the rock into volume, greatly improving drilling efficiency and adaptability to hard and complex formations. Its remarkable technology Economic benefits are regarded as one of the symbols of modern drilling technology and measurement of drilling technology, and are valued by the drilling industry at home and abroad. Pneumatic down-the-hole hammer drilling mainly begins with drilling blasting holes, water well bedrock holes and geological exploration holes. In order to expand its application scope, domestic and foreign researchers, such as the hook form and working performance of the DTH hammer, make it suitable for various projects. application requirements.

Introduction of the Drill Rods

January 17 , 2022

Introduction of the Drill Rods Seamless alloy steel pipes are made into drill pipes after several processing steps. First of all, through the processing of the steel pipe thickening process, the outer surface of the light pipe is bent inward, and the wall of the steel pipe is thickened. The next step is threading and plating with copper for strength. A non-destructive quality control inspection is then carried out, followed by welding of the steel pipe body joint. Then, the tube undergoes a welding heat treatment and a welding finish to eliminate welding residual stress. Several other tests are performed on the finished steel pipe before painting and packaging the finished drill pipe, including hardness testing, pressure testing and non-destructive testing. The drill pipe is a steel pipe with ribbing at the end, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the well. The purpose of drill pipe is to transmit torque, transport drilling fluid, connect and increase drill string, deepen wellbore to achieve normal drilling, etc. Drill pipe must be able to withstand enormous internal and external pressure, twisting, bending and vibration. During the construction of the drilling rig, the drill pipe can be used many times.
