  • Arrangement for sucking dust
    Patent number: 7798247
    Abstract: A method for sucking dust in connection with a rock drilling rig, and a rock drilling rig. The rock drilling rig (1) comprises a dust collection system provided with a suction device (11) to produce suction for sucking dust from a drill hole (8) through a first suction channel (12). The rock drilling rig further comprises a second suction channel (17) allowing the suction effect of the dust collection system to be utilized for sucking dust from a location other than the drill hole, for example from the control cabin (15). Exhaust suction is controlled by means of a control unit (26, 48).

  • Casing for noise attenuation in a rock drilling rig
    Patent number: 6199656
    Abstract: A rock drilling rig includes a movable carrier with a boom attached to it and movable in various ways. The free end of the boom is provided with drilling equipment. The drilling equipment is enclosed in a casing that prevents noise generated during drilling from spreading to the surroundings. The casing is arranged to move together with a feed beam and relative to the cradle mounted on the end of the boom. A flexible noise attenuating skirt projects forwardly from a front end of the casing for forming a sealed chamber around a drilling head.

  • Method for optimizing rock drilling
    Patent number: 4671366
    Abstract: A method for optimizing percussive drilling, especially rock drilling, in which method the operation of the drilling device is adjusted for a desired drilling result to be obtained. According to the invention, a stress wave created in a drill rod as a result of a stroke is measured and the drilling device is adjusted on the basis of the measured stress wave. The adjusting is carried out e.g. by means of the damping rate or the spectrum of the measured stress wave or the shape of the stress wave and/or the energy fed by the different portions thereof.
