Mine hoisting systems at Longgu Coal Mine

Safe and reliable production

In 2004, Xinwen Mining Group, one of the ten largest coal mining enterprises in China, awarded a significant contract to ABB for two production hoists for Longgu Coal Mine, the first of seven coal mines to be developed in Juye mining area, Shandong Province.

Coal as a major energy resource in China
Since China has a lack of oil and natural gas, coal continues to be a major source of the country’s energy. Coal provides energy for 74 percent of China’s total primary energy consumption and thus plays a critical role in the country’s economic development. Longgu Coal Mine, with annual capacity around six million tons, has therefore been listed as a National Key Construction Project by the Chinese Government.
