在苏联的露天铁矿和有色矿的开采中,牙轮钻机是最基本的穿孔设备。然而,使用实践表明,要想大大地提高劳动生产率和降低穿孔成本,必须进一步提高钻机的性能和可靠性。因此,如何保证最佳的穿孔制度以提高钻头的寿命和增加穿孔速度将是一个急待解决的问题。振动对钻头的寿命影响最大。钻杆的振幅由0.2毫米增加到3毫米时,钻头的寿命由80米降到20米。同时,也降低了钻机的生产
In the Soviet Union’s open-pit iron ore and non-ferrous mining, cone drilling rig is the most basic perforation equipment. However, practice shows that in order to greatly increase labor productivity and reduce perforation costs, rig performance and reliability must be further improved. Therefore, how to ensure the best perforation system to increase the life of the drill and increase the perforation speed will be an urgent problem to be solved. Vibration has the greatest impact on the life of the drill bit. When the amplitude of the drill pipe is increased from 0.2 mm to 3 mm, the life of the drill bit is reduced from 80 meters to 20 meters. At the same time, it also reduces the production of rigs
