  • Publication number: 20140070754
    Abstract: A mining vehicle and a method of operating a mining vehicle. The mining vehicle includes a three or more phase electric drive motor. A nominal power of the drive motor is determined on the basis of a certain drive speed and load, whereby the drive motor has a nominal torque at a certain rotating speed. The drive motor is connected to a traction wheel of the mining vehicle using a fixed gear ratio. The rotation speed of the drive motor is controlled by using a motor controller. That drive motor is operated in a delta connection on the certain drive speed and when necessary the torque of the drive motor at a drive speed lower than the certain drive speed is increased by operating the drive motor in a star connection and simultaneously temporarily overloading the drive motor.

  • Patent number: 8550180
    Abstract: The invention relates to a method for fitting a breaking device tool with a bearing, a breaking device and a tool bushing. The tool of the breaking device is fitted with a bearing with at least one bearing bushing manufactured of bearing material and arranged in a bearing space. There is a clearance fit between the bearing bushing and the bearing space, whereby the bearing bushing is insertable into the bearing space by manual force. During the use, compression stress pulses are given to the tool with a percussion device, whereby stress waves travel in the tool, which waves generate on the tool surface a movement in the direction of its perpendicular. This movement is transmitted to the bearing bushing, and it deforms the bearing bushing in the radial direction in such a way that the bearing bushing is pressed against the bearing space.

  • Patent number: 8548609
    Abstract: A method for designing a drilling pattern for rock cavity excavation and a software product implementing the method. The drilling pattern is created by means of a design program. The drilling pattern defines several starting points of drill holes in a navigation plane, end points of the drill holes on the bottom of a round and further the directions and lengths of the drill holes. The face of the round is designed to have a desired shape by determining the locations of the end points for the desired face profile. A three-dimensional face profile is entered into the design program, which subsequently places end points to the face profile automatically.

  • Patent number: 8418618
    Abstract: A method of small-charge blasting, a rock drilling unit and a front guide to be used therein. By means of a rock drill machine provided in the rock drilling unit, a hole is first drilled into a material to be excavated and, subsequently, a drilling tool is pulled out of the hole. Next, one or more propellants comprising a propellant charge are fed to the bottom of the hole through a propellant feed channel provided in connection with a feed beam. Then, the hole is sealed and the propellant is ignited, whereupon a high gas pressure is generated, which causes fractioning in the material to be excavated. During the feeding and ignition of the propellant, the rock drill machine is kept in a parallel direction with respect to the hole.
