如果能控制静态破碎剂的膨胀压力所形成的裂缝和断裂面的方向,就能以最小断裂面的长度确定破碎物的最佳钻孔布置,以期减少破碎剂的用量,获得同光面爆破一样的效果。用有限元法的应力分析和用稻田花岗岩做的破碎实验表明,断裂面的方向是能够控制的。静态破碎剂膨胀压力形成的断裂面的方向性当把静态破碎剂充填到钻孔中时,通常从钻孔的两个方向产生裂缝,形成断裂面。在花岗岩中,钻孔与裂纹垂直的情况下,可 If we can control the static crushing agent expansion pressure cracks and the direction of the fracture surface, we can determine the length of the smallest fracture surface of the crusher the best drilling layout, in order to reduce the amount of crushing agent to obtain the same as smooth blasting Effect. The stress analysis by finite element method and the experiment of crushing with rice granite show that the direction of fracture surface can be controlled. Static Crusher Expansion Pressures Direction of Fracture Placement When static crushing agent is filled into a borehole, fractures are usually created in both directions of the borehole, forming a fracture surface. In granite, drill holes and cracks in the vertical case, can
