XL Mining (Integrated Lightning Protection System)
Project Background
XL Mining Company is located in 32km North of the LY, Hunan, and the mine is located in hilly and low mountainous border zone. The relative elevation ranges from 300 to 500 meters. The slope of the terrain is generally 35 to 40 degrees. It belongs to subtropical continental climate with abundant rainfall and four distinct seasons. The annual number of thunderstorm days are in between 34.9 to 71.3. This area is exposure in high lightning and surge environment. Due to the special geographical environment and in lightning-prone areas, the power supply system, monitoring system, data network system of the mine had suffered lightning several times and caused varying degree damages.
Design of lightning protection scheme
WPX investigate the mine environment after receiving the customer’s requirements. We quickly developed a comprehensive overall mine lightning protection solution after learning the reason of damaged device. The solution include protecting mining program area, ore-dressing area, sewage treatment areas, office buildings, etc. Also several customized SPD were designed according to the special needs of regional power supply system, monitoring system and data exchange system. Then we completed the installation and arrangement of integrated lightning protection system at the assist of work staff.
