近二十年来，煤炭在中国一次能源消费中的比重一般在71.3%~ 76.5%之间。煤炭产量1996年为13.74亿吨，1998年为1.21亿吨，居世界第一位。目前我国煤炭开采以机械化为主，根据政府规划，到2000年，主要国有煤矿的机械化程度要达到80%（Li et al.，1998; Tang Dejin，1998）。
In the past twenty years, the proportion of coal in primary‐energy consumption in China is generally between 71.3% and 76.5%. The output of coal was 1.374 billion tons in 1996, and 1.21 tons in 1998, which ranked first in the world. Now coal is mined mainly with mechanization in China, which is planned to reach 80% in major State‐owned coal mines in 2000 according to the planning of the government (Li et al., 1998; Tang Dejin, 1998).
