Warrior Met Coal to open new mine no. 7 north portal facility. The $19 million North portal facility at Mine No. 7 provides a new gateway for 200 Warrior Met Coal miners to enter the northern sections of the mine. Designed for growth, it will accommodate up to 500 underground employees, adding to both the safety and productivity of Warrior employees as it is put into use. The new portal eliminates 5.1 miles of travel underground each way for miners and is located 45 minutes closer to the sections in the North, saving travel time each day. The new 33,000-plus square foot portal features a bathhouse, two kitchen areas, 40 offices and training rooms in addition to a hoist system which is double the capacity of the hoist currently in use at No. 7 West Mine. The new 7 North hoist features a 40-ton capacity, utilizing the latest technology and operates at a speed of 900 feet per minute to traverse the 1,451-foot-deep shaft. The hoist will accommodate 70 people.
