世界各国为了保证矿山施工和生产的安全,对生产过程中遇到的含水层、瓦斯、顶板破碎、松软和裂隙发育的岩层和煤层,采用了合成树脂注浆实现人工封闭含水层和加固裂隙岩层的工艺。为了满足注浆工程的需要,配制浆液的材料愈来愈多,有酚醛树脂、氨基醛树脂、不饱和聚脂树脂、环氧树脂、有机硅树脂和聚氨基树脂等,其中最常用的是各种聚氨酯类的浆液。这类浆液具有较强的防渗堵漏能力和较高的固结强度。
In order to ensure the safety of construction and production in mines, all countries in the world adopt synthetic resin grouting to realize artificial confined aquifer and reinforced fractured rock formation for rock layers and coal seams that are confronted with aquifers, gas, roof broken, loose and fissure in the production process Process. In order to meet the needs of grouting projects, more and more preparation of slurry materials, phenolic resin, amino aldehyde resin, unsaturated polyester resin, epoxy resin, silicone resin and polyurethane resin, the most commonly used are Kind of polyurethane slurry. This type of slurry has a strong anti-seepage plugging capacity and high consolidation strength.
