摘要： The invention relates to a shield structure of a rock drilling apparatus for dampening noise, the rock drilling apparatus comprising a feed beam whose one end is a drilling end, whereby the drilling end of the feed beam comprises a first shield part mounted immovably relative to the feed beam, and a second shield part mounted movably relative to the feed beam. A tubular shield flexible at least in its longitudinal direction is mounted between the shield parts, the shield being tightly attached by its ends to the first and the second shield part.

摘要： Example embodiments may generally relate to the field of mesh installation on a rock surface. An apparatus may obtain a meshing plan indicative of at least one of a planned position of at least one mesh for installation of the at least one mesh to a rock surface, or a planned position of at least one fastener for fastening the at least one mesh to the rock surface; obtain a planned surface model of the rock surface; obtain an actual surface model of the rock surface; detect a discrepancy between the planned surface model and the actual surface model; update the meshing plan based on the detected discrepancy; and control the mesh installation based on the updated meshing plan.

摘要： The invention relates to a sound dampening housing (7) for a rock drill which moves along a feed beam in a longitudinal direction thereof, the sound dampening housing (7) being attachable to the feed beam (6) of the rock drill on its both sides so that together with the feed beam (6) the sound dampening housing constitutes a substantially closed space. The sound dampening housing (7) is double-shelled, and an airspace is provided between its inner shell and its outer shell.

摘要： Example embodiments may generally relate to the field of mesh installation on a rock surface. An apparatus may obtain a meshing plan indicative of a planned position of at least one mesh on a rock surface for installation of the at least one mesh to the rock surface by a mesh installation rig, wherein the planned position of the at least one mesh is configured to be indicated with respect to a coordinate frame that is stationary with respect to the rock surface. The apparatus may map the planned position of the at least one mesh to a coordinate frame of the mesh installation rig. The apparatus may control installation of the at least one mesh to the rock surface based on the planned position of at least one mesh.
