摘要
通过研究及实践,指出采用新型本煤层钻孔封孔技术来解决使用传统方法存在的抽采浓度低、抽采量小、衰减快、微风自燃、瓦斯利用率低等问题。使用该项新技术可有效提高封孔成功率,抽放效果好,具有显著的推广应用价值。
This paper systematically introduces the research and implementation that solving the problems of low drainag Sconcentra- tion, small quantity of drainage, fast attenuation,spontaneous combustion by breeze and low gas utilization brought by .traditional method through using new coal seam drilling and sealing technology.The adoption of this new technology can effectively improve the success rate of sealing and has good gas drainage results, which has significant popularization and using value.
