Abstract

Coal mining in China is facing the transition from output to quality. Based on the total mining capacity and average production, the current situation of coal mining at mine, city, and province levels is analysed, and data in support for the layout of sustainable mining development and the optimization of output provided. The results show that 87% of China's coal is mined by underground methods, with an average production capacity of 0.93 Mt/a per mine. Open pit mining accounts for 13%, with an average mine production capacity of 5.73 Mt/a. The average mining capacity of coal mines in China is 1.05 Mt/a, with 1181 coal mines with an average capacity less than 0.3 Mt/a, accounting for 35% of the total coal mines but contributing only 4.51% to output. They are distributed in about 48 cities in six provinces, seriously restricting the transition to green coal mining. The coal industry should speed up the closure of small coal mines in key provinces and cities, eliminate outdated production capacity in the central region, increase the speed and proportion of coal resources moving westward, and promote high-quality development of coal mining.
中国煤炭开采发展现状
中国的煤炭开采正面临着从产量到质量的转变。以总开采能力和平均产量为基础,分析了矿区、市、省三级煤炭开采现状,为矿业可持续发展布局和产量优化提供了数据支撑。结果表明,中国87%的煤炭是地下开采,平均每个矿井的生产能力为0.93 Mt/a。露天开采占13%,矿山平均产能为5.73 Mt/a。全国煤矿平均开采能力为105 Mt/a,平均产能低于0.3 Mt/a的煤矿有1181个,占全国煤矿总量的35%,但对产量的贡献率仅为4.51%。它们分布在6个省约48个城市,严重制约了煤炭向绿色开采的过渡。煤炭行业要加快重点省市小煤矿关停,淘汰中部地区落后产能,提高煤炭资源西移速度和比重,促进煤炭开采高质量发展。
