摘要
煤层注水现已成为矿井预防重大事故的综合性安全技术措施.煤层注水是以解决采煤工作面煤尘问题而发展起来的,后来又逐渐应用于预防冲击地压,提高瓦斯抽放效等方面.煤体注水的好处很多,但是不同煤质会对注水造成不同的影响.针对平沟16#煤润湿性差的现象进行了研究,并提出了添加尼诺尔、十二烷基苯磺酸钠和2种表面活性剂改善其煤体的润湿性,以提高煤体注水的效果.
Coal seam effusion has now become the major comprehensive safety technical measures of coal mine accident prevention developecl from solving the problems of coal dust, then was gradually applied to prevent the shock pressure and to improve the gas drainage effect etc.. Coal injection has many advanages but different coal brings different effects on water. The difference in wettability of flat ditch coal 16# was studied, and elninor and sodium dodecyllbenzenesulfonic acid and two kinds of surfactants were added to improve its coal wetting in order to enhance the effect of coal injection.
