摘　　要：提出用高性能泡沫作为煤自燃阻化剂的载体,使阻化剂和目标煤体充分有效地接触,以充分发挥阻化性能。优选出3种表面活性剂作为发泡剂,根据表面活性剂复配原理来选择多种稳泡剂进行复配,确定了高性能泡沫的最佳配方;研究了环境温度和泡沫溶液酸碱度对泡沫稳定性的影响。The use of high-performance foam as a separate chemical agent carrier for coal spontaneous combustion can make the separate chemical agent in sufficient contact with the target coal body and the performance of the separate chemical agent to be played in full.Three surfactants were preferentially selected as the foaming agent,double crossing was conducted by selecting several foam stabilizing agents according to the double crossing principle of surfactants,the best prescription for high-performance foam was defined,and the influence of temperature and pH value on the foam stability was studied.

关 键 词：煤自燃 阻化剂 泡沫 稳定性
