Ｃｕｂｅｘ公司的Ａｃｃｒａ钻进系统是一套可编程序逻辑控制系统,可提高钻孔精度,延长钻头寿命,从而提高凿岩机生产率。借助该系统可使钻孔更直,钻头寿命更长。来自若干地下矿的试验结果表明,Ａｃｃｒａ钻进系统可使精度达到长30ｍ以上的钻孔偏差在1%以下。该系统可监测钻进压
Cubex’s Accra Drilling System is a programmable logic control system that increases drilling accuracy and increases bit life to improve rock drill productivity. With this system, drills can be drilled more straight and drills longer. Experimental results from several underground mines show that Accra drilling systems allow deviations of less than 1% in boreholes up to 30m in length. The system monitors the pressure of drilling
