煤炭是我国能源的主力军,在我国的能源消费构成中一直占70%以上。前几年,我国就进入了煤炭消耗大国的行列。我国虽然是煤炭大国,但是煤炭可采储量人均占有量仅为世界平均水平的一半,而且在已发现的煤炭资源中,勘探程度低,优质环保型资源少,有效供给能力不足。在我国尚未开采的煤层中,近90%分布在自然条件恶劣的地方,开采难度大。另外,煤炭资源回采率低,损失浪费严重。另外,与发达国家相比,我国煤矿安全状况相当严峻,事故死亡人数远远超过其他产煤国的煤矿事故死亡人数。因此,我国煤炭的供给能力受到严峻挑战。
Coal is the main force of China’s energy and has accounted for more than 70% of China’s energy consumption. A few years ago, our country entered the ranks of the largest coal consuming country. Although China is a big coal country, the average per capita possession of recoverable coal reserves is only half of the world average. Among the discovered coal resources, the degree of exploration is low, the quality and environment-friendly resources are scarce, and the effective supply capacity is insufficient. Nearly 90% of the coal seams that have not been mined in our country are located in harsh natural conditions and are difficult to mine. In addition, low recovery rate of coal resources, loss and waste serious. In addition, compared with developed countries, China’s coal mine safety situation is quite serious, the accident death toll far exceeds that of other coal-producing countries, the number of coal mine accidents. Therefore, China’s coal supply capacity is severely challenged.
