摘要
对石人沟铁矿全尾砂充填体的力学性质进行了回归正交试验研究,取灰砂比与养护时间两个因素,每个因素取三个水平进行正交试验,对试验结果进行回归分析,建立了充填体强度关于灰砂比与养护时间的回归方程。为特定强度的充填体快速制定相应的灰沙配比提供了理论工具。回归方程的建立为进一步了解充填体形成初期的力学性能以及为充填体与围岩的作用机理的研究提供了理论基础,也为进一步研究充填体随时间变化的规律提供了基本模型。
The orthogonal regression experiment on the mechanical properties of fill in Shirengou Iron Mine,two factors are cement sand ratio and curing time affiliated with three levels,and then make regression analysis of the experimental results,establishing the regression equation of the strength of cement sand ratio and curing time and providing the theories tools for that specific intensity of Backfilling to make the cement sand ratio quickly provided the theories tools.The establishment of the regression equation has provided the basic theoretical foundation for further understanding of the Mechanical Properties in Backfilling formation stage and researching on the Mechanism of Backfilling and Surrounding Rock.Also it has provided the basic model for studying the temporal variation laws of Backfilling.
