    • 摘要: 本文系统分析了岩盐单井水溶开采的特征, 应用弹性圆薄板理论对溶腔覆岩关键层进行分析, 推导出了溶腔覆岩层下沉变形微分方程和溶腔覆岩关键层上的载荷计算式, 并对溶腔覆岩关键层受力特征进行了分析, 推导了溶腔覆岩关键层初次破断距计算式, 建立了适用于岩盐单井水溶开采溶腔覆岩关键层判别的判据式, 是对以往关键层理论研究成果的补充, 为关键层理论应用于岩盐单井水溶开采溶腔覆岩移动规律研究打下了理论基础。最后, 对岩盐单井水溶开采覆岩控制研究内容和关键层理论在其中的应用思路进行了初步探讨。

       

      Abstract: This paper investigate the characteristics of salt single well solution mining, and analyzed the key stratum of salt single well solution mining cavity by the theory of elastic thin circle plate. This study provides theoretical basis for the key stratum theory applying to the moving law research of salt cavity overlying strata, and it is a new supplement research result of key stratum theory. This paper put the subsidence differential equation of salt solution mining cavity overlying strata, the stress and the first breaking distance calculation formula on the key stratum of cavity overlying strata, and analyzed the stress characteristics of the key stratum of cavity overlying strata. This paper also put the criterion equation which suitable for distinguishing the key stratum of salt single well solution mining cavity overlying strata. Finally, this paper proposed the key stratum theory in the application of the cavity overlying strata control for salt single well solution mining.
