Arrangement for Positioning Rock Drilling Rig on Drilling Site

Abstract

A method for positioning a rock drilling rig to a drilling site and a rock drilling rig. In positioning the rock drilling rig is driven to the positioning station such that its carrier is at desired distances from wall surfaces surrounding the drilling site. For positioning the rig is provided with distance measuring devices. Navigation is not started until positioning has been performed and in navigation the location of the rock drilling rig is linked to the coordinate system of the drilling site.

1 . A method for positioning a rock drilling rig on a drilling site, the method comprising:
 driving the rock drilling rig to a drilling site and positioning the carrier thereof in relation to wall surfaces surrounding the drilling site;   performing post-positioning navigation in which the location of a mine vehicle is linked to a coordinate system of the drilling site and to a drilling plan where at least the directions of holes to be drilled are determined;   initiating the drilling of the holes according to the drilling plan after the navigation;   using as a basis for the positioning of the rock drilling rig a positioning station which depends on the distance between the rock drilling rig and wall surfaces of the drilling site;   determining during positioning the location of the carrier of the rock drilling rig by means of at least one distance measuring device in relation to the wall surfaces of the drilling site; and   positioning the rock drilling rig into a positioning station for navigation.   
   
   
       2 . The method of  claim 1 , comprising determining the positioning station of the rock drilling rig in connection with a drilling plan. 
   
   
       3 . The method of  claim 1 , comprising
 displaying the measurement results of the distance measuring devices at least on one user interface, and   driving the rock drilling rig manually to the positioning station taking into account the predetermined drilling station and the distance measurement results.   
   
   
       4 . The method of  claim 1 , comprising determining the positioning station as distances from the wall surfaces of the drilling site. 
   
   
       5 . The method of  claim 1 , comprising
 measuring the location of the rock drilling rig with at least three laser distance measuring devices,   measuring with a first laser distance measuring device the distance between the carrier and the wall surface ahead and,   measuring with a second and a third laser measuring devices distances between the carrier and the lateral wall surfaces.   
   
   
       6 . The method of  claim 1 , comprising verifying prior to drilling in a control unit of the rock drilling rig that the drill unit reaches to drill the holes that are determined to be drilled with said drill unit in the drilling plan. 
   
   
       7 . The method of  claim 1 , comprising determining after navigation a vertical position of the carrier by means of at least two distance measuring devices. 
   
   
       8 . The method of  claim 1 , comprising
 determining after navigation a vertical position of the carrier by means of at least two distance measuring devices, and   using at least one distance measuring device employed in the positioning for detecting post-navigation changes in the vertical position of the carrier.   
   
   
       9 . The method of  claim 1 , comprising driving the rock drilling rig automatically to the positioning station steered by the control unit. 
   
   
       10 . A rock drilling rig comprising:
 a movable carrier;   at least one drill boom with a drill unit comprising a feed beam, feeding means and a rock drill machine;   at least one control unit, in which it is possible to store a drilling plan in which at least the direction of holes to be drilled are determined;   means for linking the rock drilling rig to the coordinate system of the drilling site by means of navigation; and   at least one distance measuring device for determining the location of the carrier in relation to the wall surfaces surrounding the drilling site,   wherein the control unit comprises at least one user interface,   and wherein the readings of the distance measuring devices are arranged for display to the operator in at least one user interface, and   the rock drilling rig is arranged to be driven for navigation in the positioning station that depends on the distance between the rock drilling rig and wall surfaces of the drilling site.   
   
   
       11 . The rock drilling rig of  claim 10 , wherein the control unit is given at least one positioning station to which the distances between the carrier and the wall surfaces surrounding the drilling site are determined, and
 wherein the control unit is arranged to display the measurements of the positioning station to the operator in the user interface.   
   
   
       12 . The rock drilling rig of  claim 10 , wherein
 the control unit is given at least one positioning station to which the distances between the carrier and the wall surfaces surrounding the drilling site are determined,   the control unit is arranged to display the measurements of the positioning station to the operator in the user interface, and   the control unit is arranged to accept initiation of navigation only after positioning the rock drilling rig to the positioning station.
