煤矿用聚氨酯煤岩体加固剂的研究进展

摘要

高分子煤岩加固剂在解决煤矿工作面塌冒治理及顶板维护、巷道加固和不良地质条件下的围岩固化等安全问题中,以其安全、高效和快捷等特点广泛应用.重点介绍了聚氨酯类煤岩体加固剂的性能特点和组成,分析了存在的缺陷,提出了相应的改进措施.简要介绍了聚氨酯类煤岩体加固剂在国内外的研究进展.%Mine chemical polymer known for its high quality, efficient characteristics can be uesd to consolidate coal and rock in solving the mining face sinking and the roof safeguard, the roadway reinforcement and the surrounding rock solidification under the unfavorable geological conditions. Emphasize the characteristic and performance of mine polyurethane, also introduce its development progress at home and abroad. Provide some corresponding improvement measures after analyzing its disadvantage.
