Patent number: 9095968Abstract: The invention relates to a tool for a breaking hammer, a breaking hammer, and the use of a breaking hammer. The breaking hammer includes a percussion device, the percussion piston of which providing impacts to the tool for breaking rock. An impact surface of the tool has a curved form surface that has a radius of curvature and a center axis on the longitudinal axis of the tool. The direction of the centre axis is transverse to the plane through the longitudinal axis of the boom of a work machine.Type: GrantFiled: September 12, 2012Date of Patent: August 4, 2015Assignee: SANDVIK MINING & CONSTRUCTION OYInventor: Ossi Kahra

Patent number: 8594832Abstract: A method and a storage device including a software product for designing a drilling pattern, and further a rock drilling rig, in the control unit of which a software product may be executed for designing the drilling pattern. For a group of holes of the drilling pattern, at least one master hole can be determined which comprises at least one dominating factor. The properties of at least one other drill hole are determined on the basis of the dominating properties of the master hole. A master hole may be a hole location master, hole depth master or hole direction master.Type: GrantFiled: February 4, 2013Date of Patent: November 26, 2013Assignee: Sandvik Mining & Construction OyInventors: Tommi Saleniemi, Erkki Eilo, Ari Junnikkala, Jussi Koskelainen, Jouko Muona, Martti Keskinen

Patent number: 8464810Abstract: A method and a storage device including a software product for modifying a drilling pattern, and a rock drilling rig. One or more holes whose location is to be changed may be selected from a drilling pattern prior to drilling. The hole is assigned a new location by means of a drilling unit and, subsequently, the drilling pattern is updated.Type: GrantFiled: April 15, 2008Date of Patent: June 18, 2013Assignee: Sandvik Mining & Construction OyInventor: Eemeli Haverinen

Patent number: 8418618Abstract: 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.Type: GrantFiled: December 16, 2008Date of Patent: April 16, 2013Assignee: Sandvik Mining & Construction OyInventors: Erkki Ahola, Veikko Räisänen

Patent number: 8342261Abstract: A method for small-charge blasting, and a rock drilling unit used therein. By means of a rock drilling machine of the rock drilling unit, a drill hole is first drilled into material to be excavated, after which one or more cartridges comprising a propellant charge are fed through a drilling tool onto the bottom of the drill hole. The drilling unit comprises a cartridge feed station, which is separate from the rock drilling machine and from which the cartridges may be fed into a longitudinal channel in the drilling tool.Type: GrantFiled: December 17, 2008Date of Patent: January 1, 2013Assignee: Sandvik Mining & Construction OyInventors: Erkki Ahola, Veikko Räisänen

Patent number: 7891437Abstract: The invention relates to a method for breaking rock to be drilled in rock drilling, in which method the rock to be drilled is subjected to successive stress pulses via a tool. The method comprises stress pulses being exerted on the rock at a high frequency, and the load proportion calculated on the basis of the values of the frequency and the length (tp) of the stress wave being at least 0.075.Type: GrantFiled: September 23, 2005Date of Patent: February 22, 2011Assignee: Sandvik Mining & Construction OYInventors: Markku Keskiniva, Jorma Mäki, Erkki Ahola, Mauri Esko, Aimo Helin
