【摘要】 基于有机高水材料注浆堵水的二次渗透特性,采用浆液渗流圆管力学模型,研究了有机高水材料浆液在含水岩层中的注浆堵水机理.结果表明:在有机高水材料注浆堵水过程中,注浆量与有机高水材料浆液的黏度成反比,有机高水材料浆液与水反应过程中生成的大量气体可形成浆液的二次渗透压力,二次渗透压力与注浆压力协同作用克服含水岩层水渗流阻力,可促进浆液在含水岩层中进一步渗透.降低有机高水材料浆液黏度,并提高其与水反应过程中气体生成量,对矿井含水岩层注浆堵水效果具有积极作用.更多还原

【Abstract】 Based on the characteristic of dual penetrating of the organic material with high water content,the mechanism of grouting for waterproof in water-containing strata was studied using a circular seepage mechanics model.The results indicate that the slurry viscosity of the materials is in inverse proportion to the grouting quantity during grouting for waterproof.The dual penetrating pressure of slurry is formed by large volume of gas generated during the reaction of organic high water-content material to water while grouting.The dual expansion and the pump pressures overcome the water seepage resistance in water-containing strata and improve sufficiently the slurry penetrating.There is a positive effect on grouting for waterproof in water-containing strata by reducing fluid viscosity and increasing gas quantity.更多还原
