Transporting materials and personnel to the affected area presented an issue due to distance and impediments between the pit mouth and worksite. The solution to be designed had to provide for:
Burrell Mining’s team worked with mine management to design and provide a cost effective supplemental support system using Turbo Props® and timbers to alleviate the problem coming from the floor as well as having considerations for possible roof issues in the future. The materials were easily adjustable for height considerations and reasonably compact allowing for efficient transportation to the work site. The support system offered low resistance to the mine ventilation system and access for examination.
