| 摘 要： | 注浆法处治煤矿采空区,注浆浆液材料选择至关重要.煤矿采空区注浆处治效果与注浆后浆液最终形成结石体强度、结石率、填充率有关.通过不同浆液配比与结石体强度、结石率、凝结时间、浆液密度、流动度之间试验研究,确定了合理的注浆浆液配比,为高速公路穿越采空区注浆治理提供依据.

| Abstract: | For using grouting method for treatment of coal mine goaf,the selection of grouting material is of particular importance.The improvement effect of treatment of coal mine goaf depends on concretion strength,concretion ratio,and filling ratio.The correlation of mixing ratio with grouting parameters(concretion strength,concretion ratio,setting time,density,and fluidity) was discussed,and the reasonable mixing ratio was also derived for the treatment of coal mine goaf.The research can be taken as a reference fo... |
