摘要
在对钙芒硝盐矿溶解渗透试验、油页岩及不同煤种热解试验研究基础上,发现矿体溶解或热解过程中,矿体中固体骨架、孔隙结构以及渗透性随溶解时间或热解温度不断衍化的规律特征。根据试验结果,结合理论分析,初步建立了原位溶浸采矿的理论架构、本构规律及耦合数学模型,为不同矿床原位溶浸开采理论建立及工程模拟,提供了重要理论指导。
In situ solution mining is a new method for liquidizing mi ning of solid deposits underground,which has advantage of safety and efficiency in technology.It possesses wide prospect of development and application in the field of underground mineral resources mining.Through experimental study of di ssolution and seepage of glauberite,pyrolysis of oil shale and coals in differe nt ranks,the development laws and properties of framework,pores and fissures, and permeability of the tested mineral rocks are found with dissolution time and heating temperature increasing.With the experimental findings and related theo retical analysis,the basic theoretical constitution,constitutive laws,and cou pling mathematical model for in situ solution mining are basically established i n the paper.It is significant for engineering simulation and practical guidance of in situ solution mining for different deposits.
