摘要
煤矿立井井筒受纵向附加力等因素影响 ,造成井壁下沉或破裂 ,使罐道装备系统发生不同程度扭曲变形 ,给安全提升带来危害。为使罐道少受或不受外力作用 ,采用“立井罐道差动联结装置”是解决这一问题的最有效县安全长久的方法。
Due to the influence of the lengthwise additional force on mine shaft tub,sidewall sinking and breaking happens,and thus results in twistificattion and deformation to cage pass equipment system,jeopardizing the security improvement.“Shatf cage pass differential connection device”is the most effective and enduring approach to such a question.
