摘要
为了解决煤层透气性差、抽放效果不好的问题,提出了边抽边掘工作面深孔松动预裂爆破增透技术,并介绍了突出煤层掘进工作面瓦斯抽放方法试验,结果表明,抽放卸压瓦斯效果较为理想,大大减少了突出危险性,安全提高了煤巷单进。
In order to solve the problems of bad coal vent and bad plumbing effect,it brings forward plumbing and digging breaking burst skill,and introduces the gas method tests of coal layer.The result shows it feasible to use the gas effect,and greatly reduces the dangers,what＇s more,improves the efficiency.
