North American Coal Corporation (NACC) is an American coal mining and mining services company. The company, now held as the main subsidiary of NACCO, is headquartered in Dallas, Texas and operates coal mines in North Dakota, Louisiana, Mississippi, and Texas. The company also contracts to provide dragline mining services to limerock quarries in Florida. ==History== North American Coal Corporation was founded in 1913 as The Cleveland and Western Coal Company, which sold coal until 1917, when it purchased three coal mines and began mining coal, as well as selling it. *In 1925, the company changed its name to The North American Coal Corporation. *In the 1950s, NACC signed its first long-term contract with an Ohio utility, issued stock to the public and expanded its operating activities into the Western United States with the acquisition of Dakota Collieries from Twin Star Industries. *In the 1960s, the company continued expanding through agreements with United Power Association, New York State Electric and Gas Corporation and The Cleveland Electric Illuminating Company. *In the 1970s, the company's Coteau Mine and Falkirk Mine were developed as non-union operations. *In the 1980s, North American Coal Corporation changed its operations from underground coal mining to surface, lignite coal mining. In 1984, the company expanded into Texas with the addition of the Sabine Mine. In 1986, North American Coal Corporation's parent company Nacco Industries, Inc was formed. In 1988, North American Coal and Phillips Coal Company formed a joint venture. *In the 1990s, the company sold its last Eastern underground mine, and expanded into limerock mining services. The company also created and signed multiple for dragline mining service contracts at its mines. In 1997, NACC and Phillips Coal Company entered into a second joint venture to develop the Red Hills Mine, the first coal mine developed in Mississippi. Also in that year, the company began to operate San Miguel Lignite Mine. *In 2000, North American Coal purchased assets of the Phillips Coal Company, including its interests in the Mississippi Lignite Mining Company, and the Red River Mining Company, as well as undeveloped lignite coal reserves in Louisiana, Mississippi, Tennessee, and Texas. These assets also included one of the most extensive bank of geological data on lignite coal reserves in the country.〔(【引用サイトリンク】title=North American Coal:About Us )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「North American Coal Corporation」の詳細全文を読む スポンサード リンク
