摘要
为了解决瓦斯抽采中巷道利用率低的问题,通过分析高抽巷、底抽巷、"一进双回"工作面外侧回风巷的特点,提出了3种巷道的"一巷两用"瓦斯抽采技术,从理论和操作上对这些技术进行了可行性分析,并探讨了钻场布置和钻孔设计、施工的技术要点.预期效果表明,这些技术拓宽了巷道的用途或延长了服务时间,在保证瓦斯抽采效果,提高采掘速度,降低生产成本方面效果显著.
To solve the problem of low tunnel utilization ratio in gas extraction,three kinds of ＂one lane with dual-use＂ gas extraction technologies have been proposed,based on the characteristics of high-located drainage roadway,floor rock drift and return airway.Feasibility analyses are made from both theory and operation.The technical points of borehole layout,drilling site design and construction have been discussed.Expected results have shown that these techniques have expanded the use or extended service hours of the lane.They can ensure effective gas drainage,improve the extraction rate and lower production cost.
