What should be paid attention to when using drill tools-YiKuang Technology
The drill rod is limited by the diameter of the drilling hole in the drilling and blasting project, and its cross-sectional area is very small. This slender rod should bear the cyclic stress of pulling, pressing, bending and twisting applied by the rock drill with high frequency and high impact under the condition of severe wear and corrosive medium. According to the different conditions such as load size and rock firmness, the rock drilling life is often only more than ten hours to more than one hundred hours. It is an engineering tool with the most demanding stress conditions, short service life, high technical content and huge consumption necessary for basic industries among all human mechanical tools. As every drill user wants to spend the least cost to get the most profit.

How to Maintain Drilling Equipment-Beneficial Mining Technology
General protective measures for high temperature, high humidity environment on the adverse effects of construction machinery, in order to reduce the downtime of construction machinery, play its maximum effectiveness, small make up two protective measures, as described below. 1. General protective measures (1) Strengthen on-site management In high temperature and high humidity environment, on-site management of construction machinery should focus on preventing rain, heat, moisture, sun and lightning strikes, and do the following work well: when improving the parking environment of machinery, when selecting temporary parking spaces, try to stay away from ravines, rivers and steep cliffs. To compact the ground foundation, dig the surrounding drainage ditch, handle the slope, clean up the surrounding weeds, eliminate snakes and mice, etc.

Application of down-the-hole drill pipe-Yikuang Technology
It is mainly used in rock drilling and crushing, anchoring drilling, geothermal air conditioning hole, water well drilling, etc. The pipe body is made of materials produced by well-known large-scale iron and steel enterprises in China. The two ends of the pipe body are internally thickened, tempered after friction welding, quenched and tempered after rough machining of drill pipe joints, and nitrided after surface finishing. The failure rates such as gluing, broken buckles, outer diameter expansion and cracking are effectively eliminated, and the pipe body is more wear-resistant and easy to disassemble. All imported precision CNC lathes and custom-made forming knives are used for thread processing. All threads are equipped with thread gauges in line with international standards, so the quality of the drill pipes produced is stable and reliable.

Maintenance of down-the-hole impactor and drill bit-Yikuang Technology
The advantages of 1. down-the-hole impactor and drill bit in water well construction 1. High drilling efficiency, long drilling tool life, down-the-hole impactor rock drilling, the medium is air, there is no problem of recovery and treatment of flushing medium, and auxiliary time is reduced. 2. The use cost is low. The down-the-hole impactor requires small shaft pressure on the drilling rig, low speed, low torque, low natural power consumption, relatively thin drill pipe diameter, easy installation and disassembly, and long service life. 3, DTH impactor drilling, the hole wall is more complete, no other media pollution, basically can maintain the original formation structure and water permeability, reduce the well cleaning time, save the cost. 4,

Treatment Measures of Underground Dust -- YiKuang Science and Technology
According to data from the National Health and Family Planning Commission, in 2017, a total of 27420 cases of occupational diseases were reported nationwide, including 24206 cases of pneumoconiosis. The number of reported cases of pneumoconiosis accounted for 88.28 of the total number of reported cases of occupational diseases in 2017, most of which were distributed in the coal industry. By the end of 2016, the cumulative number of pneumoconiosis reported nationwide has exceeded 700000 cases, accounting for 90% of occupational diseases. Mine dust, as one of the five underground natural disasters, not only endangers the health of workers, but also has the risk of explosion. With the mechanization and automation of coal resources mining is getting higher and higher, the amount of coal dust is also increasing, and the development of coal

Analysis of the causes of damage to the down-the-hole drill bit-Yiguang Technology
Mud ring wrapping Mud ring wrapping means that rock powder (chips) adheres to the surface of the drilling tool or the borehole wall to form a mud ring and wrap the drilling tool. After the mud ring is formed, the annular space becomes smaller and the debris removal is not smooth, and the debris continues to gather at the mud ring to form a mud bag, which completely blocks the borehole in severe cases, causing sticking and burying accidents. Cause analysis of formation factors: micro-water gushing and wet formation, formation micro-water gushing in the well wall to form a liquid film and make rock powder wet, well wall liquid film and rock powder bond each other to form a cuttings group, the cuttings group can not be completely taken out of the well shaft by air at the well wall, hammer head adhesion to form a mud ring, and mud group adhesion to form a mud ring phenomenon is particularly serious. Solution (1) replace the drilling process.

Crawler maintenance method of water well drilling rig-YiKuang Technology
The track tension of rotary drilling rig should be adjusted according to the soil quality in the construction process to cope with the difference of soil quality in different construction sites. This can also be done to extend the life of the machine. When the soil is soft, soil is easy to adhere to the track and rail link, so the track should be adjusted slightly loosely to prevent abnormal stress applied to the rail link due to the adhesion of soil. In the construction site with pebbles, the track should also be adjusted slightly loosely, so that the bending of the track plate can be avoided when walking on the pebbles. When the ground is firm and flat, it is best to adjust the track slightly tight. Adjustment of track tension: if the track is over-tensioned
