UG Conveyor Installations – MG32 Tripper Civil Design

The site engineers at Glencore’s Oaky No. 1 underground coal mine have engaged Orana Engineering to determine the extent of the civil work required to install the maingate tripper equipment in MG32 longwall conveyor.

On completion of the chamber mining, the finished surfaces (e.g. rib and floor) may need to be modified to accommodate the installation of the conveyor tripper equipment.  The civil design must determine the concrete grades for appropriate area drainage, adequate and safe access, concrete reinforcing for particular conveyor equipment,  while simultaneously minimising the trimming and concrete required.

Orana Engineering was provided with “As-Cut” survey data to assist with completing the civil design.  By manipulating the survey data using AutoCAD software, Orana Engineering design staff were able to accurately determine where the tripper equipment could be practically installed with minimal trimming and concrete works.  The civil design had to work within the required parameters and meet the client’s constructability requirements, including ease of tripper removal during normal longwall operations.  From this design, Orana Engineering produced a drawing set that detailed out the civil aspects of the tripper design, including tripper chamber trimming, tripper equipment mounting locations, the configuration of reinforcing and the relative levels of the concrete for drainage.

By considering the mechanical layout requirements of the tripper during the civil design, the likelihood of rework and delays during installation is significantly reduced.  For a relatively minor cost, the tripper installation can be completed efficiently and with minimal site trial and error.
