摘要:为了解决因“U” 型通风方式导致的采空区瓦斯在上隅角积聚的问题,针对150502 工作面,在计算瓦斯抽排
能力的基础上,设计高低位裂隙带钻孔来抽放采空区的瓦斯。现场效果显示,该技术可有效降低瓦斯含量和浓度,提高
瓦斯抽放利用率。

Abstract: In order to solve the problem of gas accumulation in the upper corner of goaf caused by "U" ventilation mode, based
on the calculation of gas drainage capacity of 150502 working face, this paper designed the high-level and low-level boreholes in
fracture zone boreholes to drain gas from goaf. The field effect showed that the technology could effectively reduce the gas content
and concentration and improve the drainage and utilization rate of gas.
Key words: high-level and low-level; borehole in fracture zone; gas drainage
