HARBIN, Oct. 20 (Xinhua) -- Longmay Mining Holding Group Co. Ltd, the largest coal producer in northeast China's Heilongjiang Province, started to build four new mines on Wednesday in an effort to meet the rising energy demand, as winter heating season began in the northernmost province.
Thermal power still takes up a large share of China's energy output, accounting for about 70 percent of its power generation. The heating season has added pressure to the power supply in north China.
The country is making all-out efforts to ensure power supply after power outages halted factory production and hit families in some regions.
The provincial government of Heilongjiang has approved funds worth 200 million yuan (about 31 million US dollars) to assist Longmay in smart mining technical upgrading.
