1.
Using the initial post-buckling theory and the cusp catastrophic model,the bifurcation buckling mechanism and unstability of roof strata were studied to derive the formulae of the main roof breaking convergence during the first weighting,to build the criterion of step convergence after the main roof breaking and to determine the final step convergence value.
应用初始后屈曲理论和尖点突变模型探讨了顶板岩层分岔失稳的机理及其屈曲后的不稳定性,得出了采场老顶初次来压时断裂下沉的计算公式,建立了顶板破断后台阶下沉的判据,给出了台阶下沉量。
补充资料:台阶色谱法
分子式:
CAS号:
性质:在迎头法和顶替法中,组分的浓度随时间变化的色谱流出曲线,其形状有如台阶,因此这些方法称为台阶色谱法。
