摘要:
The present invention relates to a method and a device for controlling at least one drilling parameter when drilling into rock with a drilling machine, where a percussion pressure and/or a feed pressure of the drilling machine, which generate a percussive force and a feed force respectively, are controlled during the drilling operation. A parameter value is determined that represents the mean value of a damping pressure in a damping chamber used both for transmitting a feed force to a drill string that is connected to the drilling machine, and for damping rock reflections from this drill string; a difference between the said mean value of the determined damping pressure and a reference value of the damping pressure is also determined. The percussion pressure and/or the feed pressure of the drilling machine is then controlled on the basis of this difference.
摘要(中):
本发明涉及一种用于在用钻孔机钻入岩石时控制至少一个钻孔参数的方法和装置,其中钻孔机的冲击压力和/或进给压力产生冲击力和进给力 分别在钻井操作期间被控制。 确定参数值,其表示用于将进给力传递到连接到钻孔机的钻柱的阻尼室中的阻尼压力的平均值,并用于阻尼来自该钻柱的岩石反射; 还确定所确定的阻尼压力的所述平均值与阻尼压力的参考值之间的差。 然后基于该差异来控制钻孔机的冲击压力和/或进给压力。
