  • U.S., Chinese relations strengthen through coal

    April 28, 2014

    Chinese delegates recently visited the Cordero Rojo mine in Wyoming’s Powder River Basin as part of a three-day tour of Wyoming to increase U.S., Chinese relations. The visit highlights China’s demand for American coal and the massive growth of the energy sector in China.

    China is the biggest coal customer in the world and uses four times the amount of coal annually as the United States at over 4 billion tons of coal a year. The government affairs manager for Cloud Peak Energy, Jason Begger emphasized the biggest challenge in getting Wyoming coal into the hands of the Chinese is the challenges of exporting the coal out of the northwest. This article underlines the point that the supply of Wyoming coal is contributing to the vast economic growth of China’s industrialization.

    29 cars on coal train derail east of Terry

    February 25, 2014

    A coal train derailed on Monday evening with 29 of the 115 cars going off the tracks. The incident caused coal to be strewn out from the 29 cars all over the ground surrounding the tracks. The increase of coal trains through the Montana area has dramatically increased in the past year.

    The coal was being transported from the Powder River Basin out of the Cordero Rojo mine. The mine is owned and operated by Cloud Peak Energy and was being transported to Minnesota.

    Wyoming coal mines cut production, jobs due to weak demand

    May 2, 2012

    Three coal mining companies in Wyoming’s Powder River Basin are cutting back operations due to a decline in coal demand from a warm winter and utilities moving away from coal to cheap natural gas. Peabody Energy Corp., which operates the North Antelope Rochelle, Caballo and Rawhide mines in the Powder River Basin, reduced its contact labor and temporary workers last week, totaling less than 2 percent of its Powder River Basin workforce. According to reports referring to federal employment data, cuts are estimated to be around 40 workers.

    Cloud Peak Energy, the operator of the Cordero, Antelope and Decker mines in the Powder River Basin, stated they are closely managing overtime and reducing use of contractors while trying to avoid buying new equipment. St. Louis-based Arch Coal announced Tuesday it would further curtail production for the year by idling three draglines by the middle of the year. It’s not yet clear how the decrease in production cut will affect jobs, said Kim Link, spokeswoman for Arch Coal.

    Right tool for the job

    December 27, 2010

    Western Mine Services, a mining repair company based in the heart of the Powder River in Gillette, WY, has recently made a shift from repairing equipment to actually building it themselves. Their latest creation: a prehistoric creature-looking, 53 cubic yard bucket for a dragline at the Signal Peak Mine in Montana. When on its side, it’s 15 feet tall, weighs 43 tons empty, and each of its teeth is more than a foot long.

    WMS also just finished a different coal dipper for the Cordero Rojo Mine.

    Cloud Peak Energy officials optimistic about boosting coal exports to Asia

    November 28, 2010

    Officials from Cloud Peak Energy, the third largest coal producer in the country, say that their coal exports of 3M tons this year will be almost double those of last year, and that as terminals on the west coast are built, there is a huge potential for future growth in coal sales due to the huge industrial growth in Asia. Currently Cloud Peak exports through the Westshore facility near Vancouver, B.C.; however that port is already at capacity.
