| 摘 要： | 目前,在波兰41对主要生产矿井中,有23对高瓦斯矿井进行了瓦斯抽放。2004年瓦斯平均抽放率为30%,平均利用率为39%。根据瓦斯地质条件、瓦斯涌出特点和采区通风方式,着重介绍了波兰煤矿强化煤层、围岩和采空区瓦斯抽放,提高矿井瓦斯抽放效率的工艺技术特点。在工作面的瓦斯排放中,注重开采、通风与瓦斯抽放一体化,通过优化抽放钻孔布置,取得钻孔瓦斯抽放的最佳效果,是波兰煤矿瓦斯治理的一项成功经验,成为煤矿持续安全高效生产的重要技术保障。

| Abstract: | Methane drainage is being performed in 23 gassy coal mines of total major 41 coal producing mines in Poland at present.The average methane drainage efficiency is 30 percent in 2004,with average utilization efficiency of 39 percent.In accordance with the coalbed methane geological condition,the gas emission feature and ventilation methods in mining districts,the techniques of intensive methane drainage from coal seams,surrounding strata and goaf so as to increase the methane drainage efficiency is introduced generally in this paper.The program of the degasification in longwall face highlights the integration of coal mining,ventilation and methane drainage.By means of optimization of the location of drill holes for drainage,the best methane drainage effect is obtained,which has been an expertise for coal mine methane control,and an important technical guarantee for sustaining coal safety production. |
