Scraper winches in operation The scraping of ore and moving it to the ore pass at all Anglo Platinum conventional mining operations is done by using 37 kW and 55 kW double drum single speed electric scraper winches. A 37 kW winch and one scoop are used for cleaning the face, whereas the material in the ASG and centre gulley is moved To further reduce scraper winch-related accidents, the SAMRASS database was analysed in detail to identify the major causes of such accidents in the ‘worst’ ten mines in the gold and platinum industry.

Safety challenge in use of double drum scraper winches
This is the mining environment where most of the double drum scraper winches are used in South Africa. The stoping width on conventional mines typically ranges from 70cm to 150cm. This is too narrow to apply a mechanised mining system for the stoping sections, as the minimum stoping width for mechanised mining with TMM drill machines started with their introduction at foreign mines in the middle of the XX century [11-14]. ore is transported in stopes by scraper winches. They are ICSF 2021 E3S Web of Conferences 280, 08010 innovative ones and, therefore, decrease of mining costs. Scraper haulage operations mechanization is beneath criticism.

Major Mines & Projects Tumela Mine
The Tumela Mine is situated in the province of Limpopo in South Africa, between the towns of Northam and Thabazimbi, within the North-western Limb of the Bushveld Complex. The mine operates under a mining right covering a total area of 110 km2. The current working mine infrastructure consists of three vertical and four decline shaft systems toINTRODUCTION The platinum mining industry in South Africa has, in recent times, attracted numerous creative mine-design initiatives and, as a result, has experienced some variation in mining methodology.
