摘要
本文通过力学分析,建立了适用于煤矿开采巷道中求解膨胀引起的巷道底臌的数学表达式。基于该式,对现场实际巷道进行了分析,并探讨了膨胀对巷道底臌的影响程度及其影响因素。
Throuth mechanical analysis, the formulas to calculate the opening floor heave caused by swelling are established in this paper, which are adapted to coal mining openinp. Based on these formulas, the fild openinglis analysed, the influence degree of swelling on the opening floor heave and the influence factors are studied.
