| 摘 要： | 长期以来，由于受到设备的制约，大多数矿井对薄煤层的开采仍采用炮采工艺，回采率较低，从而造成煤炭资源的大量浪费，而且工效较低，制约着矿井的生产发展。因此，研究薄煤层机械化开采技术势在必行。2003年，开滦(集团)东欢坨矿业分公司根据企业自身的实际情况和企业发展需要，着力于这一课题的研究，取得了较好效果。

| Abstract: | In a long term, due to the restriction of equipment for excavation, most mine shafts still adopt the method of demolition. Therefore, the coal recovery is very low which leads to the huge waste of coal resources. What's more, the efficiency is also very low and the production of mine shaft is restricted. So it is very necessary to study the skills of mechanical mining on the thin coal seam. In 2003, Kailuan Dong Huan Tuo branch studied the problem and got some good effects. |
