Novel organic polymer double-liquid type grouting material for coal and rock mass reinforcement in coal mine
The invention relates to the technical field of coal and rock mass reinforcement, in particular to a novel organic polymer double-liquid type grouting material for coal and rock mass reinforcement ina coal mine, which can improve the stability of coal and rock mass and reduce roof fall accidents in a coal mining process. The grouting material is composed of a component A and a component B, wherein the component A comprises an additive, combined polyol and an ether high-molecular compound; the component B is prepared from a polymethylene polyester high-molecular compound; the additives comprise a reinforcing agent, an expanding agent, a flame retardant, a catalyst and a stabilizer; the component A and the component B are injected into broken coal and rock mass through the special pneumaticgrouting pump and a mixing gun to quickly generate chemical reaction, and are cemented and cured with the coal and rock mass to generate a high-strength expansion consolidated body, so that the purpose of reinforcement or plugging can be achieved, the stability of the coal and rock mass can be improved in the coal mining process, and roof failure accidents are reduced.
本发明涉及煤岩体加固的技术领域，特别是涉及一种新型煤矿加固煤岩体用有机高分子双液型注浆材料，其在煤矿开采过程中，可以提高煤岩体的稳固性，减少冒顶事故；是由组分A和组分B组成，所述组分A包括添加剂、组合多元醇及醚类高分子化合物，所述组分B包括多甲基亚聚酯类高分子化合物，所述添加剂包括增强剂、膨胀剂、阻燃剂、催化剂和稳定剂，组分A和组分B通过专用气动注浆泵和混合枪注入破碎煤岩体后迅速发生化学反应，并与煤岩体胶结、固化生成高强度的膨胀固结体，从而可以达到加固或封堵的目的，在煤矿开采过程中，可以提高煤岩体的稳固性，减少冒顶事故。
