Description

METHOD AND SYSTEM FOR MONITORING AND DOCUMENTING THE INSTALLATION OF ROCK REINFORCEMENT BOLT
FIELD OF THE INVENTION The invention concerns a method and a system for monitoring and documenting the installation of at least one rock reinforcement bolt according to the preamble of claims 1 and 9, respectively .
BACKGROUND OF THE INVENTION
Rock reinforcement in tunnels and mines is accomplished by installing a number of rock bolts distributed over the rock faces of the walls and roofs of tunnels and galleries . To the extent that the installation is documented, this is carried our manually by notes on paper , but most commonly the installation is not documented at all .
A manual documentation process is , however, time consuming and unreliable . It is often difficult to assure the quality of the reinforcement installation, in particular since, in particular in tunnels , the rock bolts are very often covered with so called shotcrete shortly after the installation .
AIM AND MOST IMPORTANT FEATURES OF THE INVENTION It is an aim of this invention to improve a method and a system as above in such a way that the above problems are avoided or at least reduced . In particular it is an aim of the invention to provide a reliable method and system which allows economic and fast monitoring of reinforcement installations .
These aims are obtained with a method and a system according to claim 1 and 9, respectively . Hereby installation parameter data and installation position data are stored automatically so as to be subsequently available for overviewing the complete reinforcement installation so as to ensure that the installation is complete and of sufficient quality .
It is preferred that it is evaluated whether the individual bolt has been installed according to the installation parameter and/or installation position requirements in order to verify the quality of the installation of the individual bolt .
In particular it is preferred that installation parameter data and/or installation position data are compared with previously stored target data (or reference or desired data) , whereby target data can be set individually, if necessary or desired, for individual positions of the tunnel or mine to be reinforced .
In particular it is also preferred that the evaluation step results in a warning indication in the event that the comparison reveals that target data are not met . Hereby the operator can be alerted immediately and for example initiate the installation of a new bolt instead of a defective one . A warning indication should also be issued if an insufficient number of bolts are installed within a specific area .
It is preferred that stored data are transformed into a form that can be visualized, either in paper form or, most preferred, in digital image form. Hereby the data can be examined on a monitor inside or near the installation rig and/or at a remote position, for instance via the internet . A visualisation can result in 3D-images that gives a clear indication for the contractor as well as for the owner of the proj ect, so that the proj ect as a whole can be easily reviewed with respect to what rock reinforcement that in fact has been installed .
Installation parameters are, in case of an expandable tubular bolt which is expanded with pressure fluid : maximum pressure reached during expansion, duration of expansion time above a predetermine pressure level , bolt tension, bolt type, bolt length, bolt diameter , and possible volume of anchoring grout .
For a common rock reinforcement bolt which may have for example mechanical such as screw tread expansion means or no expansion means at all, here named non-tubular bolt, the installation parameters are : expansion tension, bolt tension, bolt type, bolt length, bolt diameter, . and possible volume of anchoring grout .
For other kinds of bolts , other parameters may be of interest to log .
It is preferred that during the installation process , the operator is supported by the system providing target information such as position of bolt, type of bolt to be installed, dimensions of bolt to be installed etc . It is not excluded that the entire installation is automatized or distance controlled.
Corresponding advantages are obtained with corresponding system feature claims . BRIEF DESCRIPTION OF DRAWINGS
