摘要
瓦斯危害严重威胁着煤矿的安全生产,目前瓦斯综合治理技术相对比较单一。通过对表面活性剂表面张力、临界胶束浓度及溶液对煤体接触角的理论及实验分析,得到表面活性剂的性能指标。
Gas hazard has been heavily threatening security produce, comprehensive measures on gas are relatively monotonic. Performance of surfactant can be got by pure analysis and experiment, which explores surfactant' s critical micell concentration, surface tension and coal's contact angle.
