Material for quickly sealing easily-weathered surrounding rock of coal mine bottom drainage roadway and use method of material
The invention discloses a material for quickly sealing easily-weathered surrounding rock of a coal mine bottom drainage roadway and a use method of the material, belongs to the technical field of mining engineering, and can solve the problems that the existing coal mine roadway concrete guniting material is large in quantity, has potential safety hazards in transportation, pollutes a construction environment, affects excavation connection, is poor in long-term protection effect and the like. The material comprises a component A and a component B. The component A is liquid water-based polymer resin, the component B is an ultrafine inorganic powder mixed material, and the mass ratio of the component A to the component B is 1: 1. By the adoption of the method, the surrounding rock can achieve the overall protection effects of rapid sealing, cracking prevention, air leakage prevention, water leakage prevention and the like, and it is guaranteed that a roadway is complete, safe and stable.
一种用于煤矿底抽巷易风化围岩快速密闭的材料及其使用方法，属于矿用工程技术领域，可解决现有煤矿巷道混凝土喷浆用料大、存在运输安全隐患，施工环境污染，影响采掘衔接，长期防护效果差等问题，包括A、B双组分，其中，A组分为液体水性聚合物树脂，B组分为超细无机粉体混合材料，A组分和B组分的质量比为1:1。采用本发明可以使围岩达到快速封闭、防开裂、防漏风、防渗漏水等整体防护效果，保证巷道完整、安全稳定。
