摘要
分析了井内坠物发生的原因，给出了坠物在井内受阻时的运动方程及影响规律。计算了坠物下落速度、加速度和坠落力。为立井延深保护设施的设计提供了科学依据。
This paper analyzes the causes of the occurrence of falling body in the shaft.the equation of the falling body motion is given in consideration of the resistance.The falling velocity of the falling body,the acceleration and falling force are calculated The regulation of effect of every related parameter on the falling mation is quiven, providing a reliable basis for the design of the protective device in shaft deepening and safety construction.
