ABB supplied Xinwen Mining Group, one of the ten largest coal mining enterprises in China, with two production hoists for Longgu Coal Mines, developed in Juye mining area, Shandong Province
One of China’s largest underground shaft mines
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.
Longgu Coal Mine began production in 2007. The Shandong Xinwen Mining Group invested in and built the mine. With its designed production capacity of 6 million tons per year, Longgu Coal Mine is currently one of China’s largest underground shaft mines in terms of production capacity. The entire mine area at Longgu provides 1.68 billion tons of coal reserves, of which 510 million are recoverable.
The coal is low ash, low sulfur, low phosphorus but high-quality coking coal with high calorific value.
Longgu Coal Mine has two main production shafts to which ABB delivered two complete mine hoists. One service shaft where ABB delivered the control system, electrical equipment and brake system to the service hoist as well as one ventilation shaft. The total investment in the mine reached 3.06 billion RMB, and the designed service life cycle is about 70 years.
