煤炭是不可再生资源,也是我国现阶段的主要能源。据权威研究报告显示,至2036年,煤炭在我国能源消费中的比重仍将占71%左右。尽管我国煤炭资源丰富,可是经济可采储量较少,人均探明开采储量仅为全世界平均值的1/3。研究特殊煤层,比如薄煤层的开采等有重要的现实意义。 Coal is a non-renewable resource and also a major source of energy in our country at this stage. According to authoritative research report shows that by 2036, the proportion of coal in China’s energy consumption will still account for about 71%. Although China is rich in coal resources, its economically recoverable reserves are small, with reserves per capita proven to be only 1/3 of the world average. Research on special coal seams, such as the mining of thin coal seams, has important practical significance.
