摘要
近年来,随着煤矿井下开采深度的增加,煤矿生产的日趋集中,矿井、特别是采区的瓦斯涌出量增长很快,单纯用通风方法解决瓦斯问题已不再合理,瓦斯抽放作为治理瓦斯的有效手段则发挥着越来越重要的作用。介绍了低透气性薄煤层瓦斯抽放方法及使用效果。
In recent years,along with the coal mining deep gradually increasing,coal mine proadction is getting concentration,mine,especially the mining area,the amount of gas gushed out increase very quickly.The simple ventilation methods can＇t solve the gas problem.The gas drainage as an effective method will exert more and more important function.
