液压支架底座柱窝充填块的研究

通过研究煤炭的安息角,设计了一种带有自卸煤矸滑台的新型立柱柱窝充填块,能够防止煤矸在充填块上堆积,最大限度地降低柱窝上方空间及立柱与柱窝配合面的煤矸侵入量。保障立柱在柱窝内摆动灵活不受煤矸阻碍,减缓立柱和柱窝配合面的磨损。

Design of Hydraulic Base Column Filling Block of Needling

Coal repose through research,design a slide with a new type of gangue dump column filled nest block,can block to prevent the accumulation of waste piles in the filling,to minimize the nest at the top of column space and column and the column with the surface of the gangue nest intrusion volume.Security column in the column from the gangue fossa swing flexible barriers slow column and column nest with surface wear.
