1. Demonstration of deep hole drilling technology in high altitude area
At an altitude of 5200 meters, Tibet's Ali Tieglong mining area uses a YN-1800 full hydraulic drilling rig with an N-caliber final hole and a depth of 1280.48 meters.
At an altitude of 4200 meters, the Shi Ying porphyry formation of the Pulang Copper Mine Project adopts a YN-1800 full hydraulic drilling rig with an N-diameter final hole and a depth of 1500.68 meters.
2, large angle precision deep hole drilling technology demonstration.
Lanling Iron Mine has a 1200-meter borehole and a 78-degree inclined hole with an accuracy controlled within 1.2 degrees. P-diameter drill pipe is guided to drill with small annular clearance, and H-diameter asymmetric drill tool is used to control running deviation.
Qianxi Jinchangyu gold mine, 58 degrees inclined hole, rock broken, easy shrinkage diameter formation. Using YN-1500DL electric full hydraulic drilling rig, HY high rigidity straight rope drill pipe HC2 thin wall centralizer X series adaptive guide drill bit high speed controlled pressure drilling.
3, easy to run oblique formation drilling technology demonstration.
Dandonggou gold deposit, Liaoning Province, phyllite is easy to run oblique strata. Adopt YN-1500 full hydraulic drilling rig, HX rope drill pipe asymmetric drilling tool bionic drill bit technology for rapid drilling.
4. Demonstration of high-efficiency drilling technology for 2000 m deep drilling in iron ore formation
Benxi iron ore strong slope formation, 2000 meters deep vertical drilling. H-diameter drilling tools are used to straighten the drill string, and pressure-controlled rapid drilling is used to ensure drilling accuracy. It takes 98 days to finish the hole with high accuracy.
5. Demonstration of drilling technology for rich iron ore in kilometer overburden
A rich iron ore in Yucheng, Shandong, 920 meters overburden. Combined with common drilling and rope coring technology, the core taking rate of overburden reaches more than 90%, and the inclination angle is kept within 1 degree.
6. Demonstration of rope coring drilling technology in sandstone formation
For sandstone type formation, CS series rope coring drilling tools are used instead of lifting coring.
7, Asia's largest copper mine-the second space 2000 meters deep drilling drilling technology demonstration.
Tongling Dongguashan Copper Mine, kilometers of underground roadway space, the first underground 2000 meters deep vertical drilling construction in China. Independent research and development of YH-2500D electric full hydraulic drilling rig, HX direct rope drilling tool X series drill bit fast drilling.
8, Ultra-high temperature environment drilling technology demonstration in desert area
In a super-large copper mine in Saudi Arabia, the surface temperature is above 50 ℃, the drilling depth is 955 meters, and the inclination angle is 55 degrees. YN1500 full hydraulic drilling rig C series drilling tools are used, which takes 23 days to finish the hole.
9. Demonstration of efficient drilling technology for copper-cobalt ore belt formation
Congo (DRC) and Zambia mining areas, broken + fissure + honeycomb rock formation, YN-800 type full hydraulic drilling rig + HY drill pipe + HC3 drilling tool, high precision inner pipe system, core taking rate above 90%.
10, coal formation rope coring drilling technology demonstration.
For coal measure strata, YN-1500 full hydraulic drilling rig + T series drill pipe + three-layer pipe drilling tool system is adopted, with large annular space clearance for drilling, and the coal seam adoption rate is above 90%.
11, 1500 meters complex formation drilling overall solution
Using YN-1500 drilling rig, supporting PC\HC\NC standard drill pipe drilling tool high precision inner pipe system, complete 1500 m complex formation drilling.
