摘要
煤层注水技术是一种超前防治煤炭自燃的手段,但单纯注水润湿效果不太理想,现利用注水添加渗透剂克服以上不足,针对优选出的渗透剂SDS,设计出渗透剂正向润湿实验和反向润湿实验,得到最佳煤层注水添加SDS浓度为0.10%。
Coal seam water injection technology is an advanced means for the prevention and control of coal spontaneous combustion. But pure water injection effect is not ideal,now using penetrative agent overcome the above shortcomings,specific to optimized penetrant SDS,by penetrant forward and reverse wetting experiments,concluded the best seam infusion SDS concentration is 0. 10%.
