| 摘 要： | 采煤回采至停采线之前,上下巷经常不同步,为了减少煤炭的损失,提高回采率,我们采取新的回采方式,即伪倾斜开采和上巷前进式、下巷前进式回采,对三角煤进行了回收,保证了煤炭损失量降低到最小,为新立矿提高了经济效益. |
| 关 键 词： | 伪倾斜开采 前进式回采 三角煤 |

| Abstract: | when extracting coal prior to the stop line,the upper and lower entries are often not in-step.The new stopping methods,or pseudo-declivity mining,upper entry forging ahead and lower entry forging ahead extraction methods,are adopted to recover triangle coal for the purpose of reducing the loss of coal and enhancing the recovery ratio,which has ensured to reduce the loss amount of coal to the minimum and raised economy benefits for Xinli mine. |
| Keywords: | pseudo-declivity mining forging ahead extraction triangle coal |
