How to choose mud when diamond drill bit encounters geothermal water
The normal drilling construction with diamond drill bit is usually done with clean water, because it can be used locally, without transportation, without cost, etc., by the majority of the captain as the first choice of flushing fluid. However, in many cases, it is still necessary to use mud to replace the water to flush the borehole, such as the situation containing geothermal water during the drilling process.

Increase spiral drill pipe life?
In the coal mine drilling equipment, spiral drill pipe is the most common use, how to make the use of spiral drill pipe life growth, this is our long-term consideration of the need. The way to improve the life of the spiral drill pipe is mainly from the material of the spiral drill pipe, the consumption process, the use of various aspects such as comprehensive thinking, focusing on the treatment of thin links, from time to time to improve and perfect the process request. The following two points are the direction to improve the life of the spiral drill pipe. 1, from the structure of the rock drilling machine to stop from time to time to improve, for example, from the pneumatic rock drill one big piston and the other small piston to the hydraulic rock drill equal diameter cylindrical piston, in ensuring

The difference between ordinary slotted drill pipe and enhanced slotted drill pipe.
High-enhanced grooving drill pipe is an updated product on the root of common grooving drill pipe. The consumption of grooving drill pipe data is made of high-enhanced alloy steel and special seamless steel pipe for drilling. The blank is forged, non-oxidizing heat treatment, and the thread is processed with high precision by numerical control machine tools and special tools. Therefore, our products have the characteristics of high enhancement, high rigidity, high fatigue load resistance and good wear resistance, which can fully exert the performance of drilling rig.

Rib drill pipe product characteristics and maintenance instructions
1. The rib drill pipe shall be stopped for regular maintenance and maintenance, and the anti-rust and dustproof disposal shall be stopped regularly. 2. The use of rib drill pipe shall be within the rated drilling distance of the drilling rig, and the matching rib drill pipe shall be adopted according to the technical parameters of the drilling distance. 3. Geological rib drill pipe is made of special geological drilling pipe for mining geology and its matching joints by friction welding, so it has good follow-up and high tensile strength, and can adapt to drilling and gas discharge in the regular. When working in hard rock, coal seam or other special environment, it is necessary to confirm the drilling depth according to the physical properties and parameters of the practical material of the rib drill pipe.

How to match the geological drill pipe with the drilling rig?
Small diameter geological drill pipes of φ34mm-φ50mm can be used together with pneumatic column drilling rigs (ZQJC160 to 1000) with torque below 1000N/m/full hydraulic tunnel drilling rigs for coal mines (ZDY400, 540, 650, 1200). Large diameter geological drill pipes above φ63.5mm are generally used together with full hydraulic drilling rigs (ZDY1900, 3200, 4000) and crawler type full hydraulic tunnel drilling rigs (ZDY6000).

Operating Steps and Precautions for Drill Pipe of Rotary Drilling Rig
The drill pipe and drill bit of the rotary drilling rig can only be used for the drilling of pile holes, and are not allowed to be used for soil handling, handling or leveling of the construction site. Never immerse the drill in liquid concrete. And only when the drill bit contacts the bottom of the hole to start the drilling operation.
