摘要
目前,国内深孔凿岩的钻孔精度普遍较低,这一现状严重地制约大直径深孔采矿工艺的进一步发展。鉴于此,本文详细分析了导致偏斜的各种因素,提出了控制钻孔偏斜的各项措施与方法,从而指导深孔钻机的设计、制造与操作。
Generally, the precision of longhole drilling now is fairly poor in China, which seriously restricts the development of the large diameter longhole mining technology. In consideration this, all factors contributing to longhole deviation are analysed in detail. Various measures and methods for control of the deviation are proposed , which will serve as a guide for the design, manufacture and operation of the longhole drill.
