Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
The company Bergteamet, Boliden, Sweden, is installing ventilation shafts of the Garpenberg mine. For such work a platform is needed which you can stand on and work from. The Shaft Reinforcement Team at Bergteamet performs the installation work and is the sponsor of the platform. The project described in this report is performed at the department MEC, Mining Equipment Construction, which has been given the task to design and construct the platform, customized for the current shaft. After this the platform is manufactured and inspected at the workshop at Bergteamet.
The design work was carried out as follows:
- After an initial meeting a requirement specification was worked out, describing the problem and previous experiences of platforms and requirements for the design and equipment.
- A concept sketch was developed with consideration of surrounding factors.
- A constructed 3D model was presented along with the choice of materials. Improvements were made after feedback from Bergteamet.
- Development of production drawings. The drawings were reviewed and handed over to the preparer for manufacturing.
The result was a platform designed with different square tubes where the floor follows the geometrical shape of the shaft. The platform is suspended from a rectangular center tube with dimensions 100x100x8, which is centered in the shaft. The purpose of a center tube is that it facilitates the final stage of the work in the shaft, namely the installation of a fall protection. The platform has a roof to protect from stone rain and dripping water. Under the floor is an air tank places to run the air-powered outriggers. Around the workplace there is a guardrail with a door for access and egress. The design work was done using the drawing program SolidWorks. Calculations were made by hand.
The platform fulfills the requirements defined by the trade organization for mine elevators in Sweden, (BRAGS), as well as Bolidens for the design and Bergteamets internal design requirements. The platform has been manufactured, inspected and soon filled its purpose for the shaft installation in the Garpenberg mine.
