摘要
介绍切顶支柱使用现状,在着重分析目前切顶支柱存在支撑力不足,受到顶板冲击容易倾斜等问题的前提下,结合采煤工作面的实际工况。针对存在的问题给出相应的解决措施,并分析改进后的使用效果,对将来切顶支柱的设计提出展望。
Introduce the present application of breaking-off prop in this paper, mainly analyze some limitation of this prop, such as support deficiency, lean easily when it gets impulse of terrane, also combine actual situation of working face, and come up with corresponding solutions towards the questions analyzed, then give a blue print of future breaking-off prop design
