The features of the sub level caving hydraulic support:low position of dropping coal with four props to support, stable supporting, continuous coal dropping,less lose on the back, better effect in dropping the coal, when cutting through the thick coal seam, it produces more with fewer investing. It adopts the seam of coal whose hardness in under middle level, joints and the gaps develop well.
