摘　　要：为了减少瓦斯尾巷掘进工程量和资金投入,缩短工作面接替时间,在南庄煤矿15#煤层8820工作面考察了不同通风和抽采方式下瓦斯浓度和瓦斯涌出情况,研究取消瓦斯尾巷的可行性。研究表明,15#煤层回采工作面在取消瓦斯尾巷后,采用"U"型通风方式结合高抽巷瓦斯抽采可以解决工作面瓦斯问题,为后续回采工作面通风系统选择提供了依据。In order to reduce the engineering quantities of gas tail lane and capital investment, and to shorten time for the replacement of working face, the feasibility of cancelling gas tail lane was studied, on the basis of the gas concentration and the gas emission at No. 8820 working face in 15^# coal seam in Nanzhuang Coal Mine under different methods of ventilation and gas drainage. The results showed after cancelling gas tail lane, the gas overrun was solved by the combination of U-shaped ventilation with high-level drilling for gas drainage, providing a basis for the choice of subsequent ventilation system.
