Abstract
A process and an arrangement for controlling rock drilling on the basis of the pressure in the pressure duct for the drive motor of the drill rod. In the process, the pressure in the pressure liquid duct of the drive motor is measured during the rotation, when the drill bit is not in contact with the drilling rock, and the control is subsequently exercised during the drilling on the basis of the difference between the pressure value during the drilling and the pressure value at idle. In the arrangement, the rock drilling device incorporates a control unit, which measures the pressure in the pressure liquid duct of the drive motor when the drill rod rotates without contact with the drilling rock and stores this value in a memory and controls the rock drilling device on the basis of the difference between the pressure value measured during the drilling and the pressure value at idle. <IMAGE>
