在坚硬与极硬岩层中进行铅锌工业矿山研究所（НИГРИС）拟定的振动迴转钻进爆破钻孔时，振动器3带劫冲击钻头1连同钻杆柱2沿轴向Z作振动运动并假助方形钻杆4和转盘5绕该轴心迴转（图1）。插有钻杆柱的振动器用绞车7之钢绳6提吊，绞车供升降工作和调整钻具对孔底的压力使用。通过钻杆柱经钻头排注水液冲洗钻孔。利用振动与迴转时因钻头冲击而在孔底造成岩屑的循环剥离方式破碎岩石。随著钻孔的加深进行接长钻杆柱。
Vibratory Drilling Blasting Drilling, developed by the Institute of Lead and Zinc Industry Mining (НИГРИС) in hard and ultra-hard formations, vibrates the shaker 1 along with the drill string 2 in the axial Z Leave the square drill rod 4 and turntable 5 around the axis of rotation (Figure 1). A vibrator inserted with a drill string is hoisted by a wire rope 6 of a winch 7, which is used for lifting work and adjusting the pressure of the drilling tool on the bottom of the hole. Drill through the drill pipe column drill bit liquid water flushing. The use of vibration and rotation due to the impact of the drill hole in the bottom of the hole caused by the cycle of peeling stripping rock broken. With the deepening of drilling to drill long drill string.
