| 摘 要： | 在新鲜煤壁瓦斯涌出强度大的问题上,根据表面活性剂的润湿性、分散性、稳定性以及考察目的,选择十二烷基苯磺酸钠与洗涤灵按2∶1的比例配制了实验试剂,提出了利用表面活性剂降低瓦斯涌出强度的技术方案,并在实验室做了颗粒煤对瓦斯的吸附与解吸实验。实验结果表明:颗粒煤经过喷洒十二烷基苯磺酸钠和洗涤灵配制的表面活性剂溶液后,表面活性剂溶液能够很好地渗透煤体,使煤样润湿程度增加,堵塞了瓦斯的运移通道;活性剂溶液渗透到煤体孔隙内部,对煤体起到了降温的作用,低温有利于瓦斯吸附,抑制吸附瓦斯转化为游离瓦斯,瓦斯涌出强度会降低10%~40%左右,从这两方面达到降低瓦斯涌出强度、避免瓦斯超限的目的。 |
