Anti-seepage reinforcing grouting material and preparation method thereof
The invention discloses an anti-seepage reinforcement grouting material especially used for a dam body of an underground reservoir of a coal mine, a preparation method of the anti-seepage reinforcement grouting material and an anti-seepage reinforcement grouting method. The anti-seepage reinforcing grouting material comprises a component A and a component B. The component A comprises gangue mineral powder, superfine cement and water, the average particle size of the gangue mineral powder is 0.019 mm or below, the average particle size of the superfine cement is 0.019 mm or below, the weight ratio of the gangue mineral powder to the superfine cement is (0.5-3): 7, and the component B comprises a component C and a component D, the weight ratio of the water to the sum of the gangue mineral powder and the superfine cement is 1: (0.8-1.5); the component B is water glass, and the baume degree of the component B is 20-40; and the weight ratio of the component A to the component B is 10: (0.1-1). According to the reinforcing grouting material, waste gangue in the coal mining process is fully utilized, the resource utilization efficiency is improved, the production cost is reduced, and meanwhile, a consolidated body formed by the waste gangue is good in toughness and deformation resistance.
本发明公开了一种特别用于煤矿地下水库坝体的防渗加固注浆材料，其制备方法和防渗加固注浆的方法。所述防渗加固注浆材料包括如下组分：组分A，其包含矸石矿粉、超细水泥和水，其中，所述矸石矿粉的平均粒径为0.019mm以下，以及所述超细水泥的平均粒径为0.019mm以下，并且所述矸石矿粉与所述超细水泥的重量之比为0.5～3∶7，水与所述矸石矿粉和所述超细水泥之和的重量比为1∶0.8～1.5；组分B为水玻璃，其波美度为20～40；并且组分A与组分B的重量比为10∶0.1～1。所述加固注浆材料充分利用了采煤过程中的废物矸石，提高了资源利用效率，降低了生产成本，同时由其形成的结实体，韧性好，抗变形能力较好。
