Coal mining is a tough business to turn around, and for many coal companies it’s a hard sell.

The collapse of the Murray-Darlington coal mining industry has left many miners with the loss of a lifeline and a lot of job losses.

But the company that took it over from the federal government in 1977 is still going strong.

Murray-darling Basin Coal Mine was a joint venture between the Murray brothers and the U.S. Department of the Interior in 1977.

The company went public in the early 1980s and went on to be one of the most successful coal mines in the country.

The coal mines operated for almost 50 years and produced a tonnage of coal equivalent to more than 2.7 million cars.

It was the largest coal mine in the world, and in the 1980s the company had about 3,400 employees.

The Murray brothers died in 2006.

A former mine manager from the mines past, Bill DeWitt, is the current Murray-darlington vice president of operations and has been in the job since March 2018.

He tells the New York Times that his current position is an extension of what he did at the mines.

He told the Times that Murray- Darling Basin had the biggest coal mine there, but he also told the paper that the company is now “a whole lot more profitable” with fewer workers and a smaller workforce.

The Murray- Darlington coal mines were one of several mines owned by the U:Co Resources in a variety of projects in the mid-1970s and 1980s.

The mines were operated by the Department of Commerce under the Murray Brothers’ joint venture, U:CO Resources.

The Department of Interior had a monopoly on the production of coal in the West.

In the early 1970s, the Department began using the coal from the Murray coal mines to supply the electrical power for the Hoover Dam in California.

According to DeWert, the company began selling its coal at a loss, and had to close mines at a time when it was losing millions of dollars.

“I don’t think the federal mine law allowed us to survive and we just got into this,” DeWerts father told the Associated Press in 2007.

DeWert said he quit his job as an engineer at the mine in 1977, after the company failed.

He then went to work for the federal Bureau of Land Management, working on mining and timber leases.

After leaving the mine, DeWercks father worked for a private firm, and eventually returned to the mines to help out.

In 1984, he bought the Murray Mine Company and in 1991 purchased the mine.

In 2002, the mine closed its doors and the company moved into the Murray Coal Building.

DeWerets father has been involved in the company since it was taken over by the new owners in 2013.

But DeWerys father says that the mine had a lot to offer the community.

“We had this fantastic coal mine.

It had a very nice history and a great history,” he told the AP.

In 2017, Murray- darling Basin said it would sell its assets and that it would invest in other mines.

The new owners are seeking a $1.3 billion loan to build a new mine in Arizona.
