我国煤炭储量中薄煤层占21.6％。薄煤层工作面机械化不但能提高煤炭产量,改善工人的劳动条件,而且能加快解放层的开采,便于煤矿合理布置、安全生产。目前,国产的滚筒式采煤机种类不少,各个煤矿的具体条件又有所不同,只有因地制宜选择适当型号的采煤机,合理地进行工作面设备总体配套,才能最经济最有效地发挥机械化采掘的优势,达到高效安全生产的目的。 China’s coal reserves accounted for 21.6% of the thin seam. Mechanization of the working face of thin coal seams will not only increase coal output, improve working conditions of workers, but also speed up the liberation of the mining, to facilitate the rational arrangement of coal mines, safe production. At present, there are quite a few types of drum shearers domestically produced, and the specific conditions of all coal mines are different. Only when the coal shearer of the appropriate type is selected according to local conditions and the overall equipment of the face equipment is reasonable, can mechanization be most economically and most effectively utilized The advantages of mining, to achieve the purpose of efficient and safe production.
