由于去年推出了几种主要的新型钻机(仅 B-E 公司就推出三种),大直径炮孔钻机市场将出现新的竞争。露天采矿的这种关键设备将继续向钻进速度更快,成本更低的方向发展。许多钻机现在都装有监控器,为钴机司机提供旋转速度、扭矩、轴压和钻头所在深度的机上信息。这有助于司机选择正确的参数调定值,而且也有助于编制采矿计划 With the introduction of several major new rigs last year (only B-E introduced three), there will be new competition in the market for large-diameter blasthole drills. The key piece of open-pit mining equipment will continue to move faster and at a lower cost. Many drills are now equipped with monitors that provide the cobalt driver with onboard information on rotational speed, torque, axial pressure, and depth of the drill bit. This helps the driver to select the correct parameter setting and also helps in the preparation of the mining plan
