摘要
根据目前钻孔抽采瓦斯浓度低的普遍现象,提出了影响钻孔瓦斯抽采3个最为重要的因素:煤层的透气性、钻孔的密封性及钻场周围地质条件。并对这3个方面进行了较为详细的研究,提出了解决问题的办法,最后结合煤矿现场实际瓦斯抽采情况来进一步验证。
According to the general phenomenon of low gas concentration in the current drilling extraction,proposing three of the most important influence factors of drilling extraction： the gas permeability of coal seam,hole sealing and geological conditions around the drilling field.These three aspects are researched in detail,and putting forward the solution to these problems,finally combining with gas extraction of actual field to further verify.
