Core Hole Drilling is a drilling technique whereby an oil or gas well is drilled either in a vertical hole or horizontal hole. The method used to drill a vertical hole is known as vertical drilling whereas for a horizontally drilled hole is known as horizontal drilling.
The core drill rig of full hydraulic and rotor adopted the technology of wire-line coring has been the dominant type rig for solid mineral deposits prospecting in developed counties of the world. The rig is light, simple in structure, and easy for transportation. The mast has the functions of sliding and touching ground, the spindle lifted and lowered with hydraulic cylinder. It could be folded for transport and relocation. The spindle hole is in large diameter.
It is a thoroughly new-type wire-line Core Drilling Rig developed on the basis of the market demand and the advanced techniques in the world. It is mainly used for metal&nonmetal solid exploration and exploration of coal-bed methane, nature gas mining, hydrogeology well drilling, geothermal well drilling, mining gallery, ventilation and drainage of exploratory and emergency construction projects.
In most cases, it can drill into stratums with depths of more than 350 meters and more than 500 meters and can be widely used in core drilling work with extremely complex ground conditions.
It is ideal equipment for deep-hole geological exploration drilling. Contact us to get a cheap YK core drilling machine price. Ores Prospecting and Lab Experiment,underground prospecting,geological investigation Henan YK Prospecting Machinery Co., Ltd , https://www.yyphotovoltaicpilingrig.com
To improve energy and economic efficiency, NYK has installed a new generation of energy-saving fluorescent lighting system "E?COOL" manufactured by Optrom, Inc. of Japan on its six car carriers. It is reported that since April 2012, about 13,000 fluorescent lamps have been replaced by “E?COOLâ€.
“E?COOL†uses a cold cathode fluorescent lamp (CCFL), which has the advantages of longer life cycle and less power consumption, brighter illumination and no flicker, saving about 40% of power compared to conventional fluorescent lamps. When a car boat lighting system is replaced by "E?COOL", it can reduce carbon dioxide emissions by 1%. In FY13, NYK plans to replace approximately 40,000 traditional fluorescent lamps with “E?COOLâ€.
