According to numbers released by the U.S. Mine Safety and Health Administration (MSHA), Wyoming’s coal mine workforce fell by 137 employees in 2018 as did coal production in the state which produced 294 Mt (304 million st) of coal in 2018, a drop of about 10 Mt (12 million st) from the previous year.
Wyoming leads the nation in coal production with about one quarter of the nation’s coal coming from the North Antelope Rochelle and Black Thunder mines in the Powder River Basin. However, The coal market in the state and nationally has declined in recent years as natural gas power and, to a lesser degree, renewables have gained ground. That structural change hit a pivot point in 2015 when Wyoming’s largest producers saw a sudden decline sweep away about one quarter of the state’s annual coal production. That downturn also pared back the number of miners in the state by nearly 1,000.
The Casper Star Tribune reported that support for the coal industry from the Trump administration has led to various attempts to reduce environmental regulations that have burdened coal-fired power generation. Still, the industry continues to face market pressure.
Travis Deti, executive director of the Wyoming Mining Association. Deti said the association goes by state production and employment counts that are expected to be published soon, but he said the federal numbers, showing approximately a 3 percent decline, are what’s expected.
In 2017, the state report showed just five full-time coal mining jobs had returned following the nearly 1,000-worker drop from the downturn.
The sector is variable season by season, according to gas prices and weather. But the mines are holding a steady yearly production count right now, Deti said.
Peabody Energy’s North Antelope Rochelle mine near Wright produced 89 Mt (98.3 million st) in 2018. Arch Coal’s nearby Black Thunder produced 64 Mt (71 million st) for the year. North Antelope was slightly down and Arch slightly up compared to 2017.
As the largest employers, and producers, in the state, the mines’ success ripples across the data basin wide. North Antelope Rochelle had 101 fewer workers in the fourth quarter of 2018 than at the end of the previous year. Nearby Black Thunder was down 33 workers compared to the final quarter of 2017. Late in the year, Arch was expected to move about 100 miners from its smaller Coal Creek operation to Black Thunder. Such a move would leave Coal Creek with just a few dozen employees.
Weather continues to be a significant factor in how well Wyoming mines do from one quarter to the next, Deti said, noting the line of train cars filled with coal visible up and down the highway through Powder River Basin this winter.
With a historic cold snap hitting the Midwest, the current quarter is expected to improve in Wyoming.
The Powder River Basin is flexible and can ramp up or down according to the demand from the power sector, Deti said.
“We are not building more coal-fired power plants, but when those (existing) coal plants need to ramp up, and we need to increase production, the basin is certainly able to do that,” he said.
More than half of the country’s coal mines have closed since 2008, according to the Energy Information Administration. Ten years ago the country had 1,435 active coal mines. Today there are 671. Most closures were smaller, less efficient operations in Appalachia burdened by expensive regulatory upgrades and the tightening market.
