| 摘 要： | 本文利用空间问题的弹性理论计算和分析了采动影响下的底板应力分布,并参照以往学者的研究成果,利用最小势能原理和极限平衡原理,分析了底板含水层易在采空区和采场突水的原因.同时根据计算和分析结果,提出底板巷道应布置在超前支承压力影响深度Z_0以下;缩短工作面长度可以减轻底板突水.并将分析结果与现场实测结果进行了比较,证实了本方法的可靠性.

| Abstract: | Based on the space elastic theory, this paper calculates and analyses the stress distribution in the extracted floor . Furthermore, refering to the previous research achievements and employing the principle of the least potential energy and the theory of limitation equilibrium, it also analyses the reason why the water-bearing stratum is apt to burst into water in the goave and the face. According to the computed and analysed results, it is suggested that the floor road should be arranged below the influential depth of the forward abutment pressure (Z0 ) , which has proved its reliability by comparing the survey results in-situ with the calculated results. |
