Abstract Underground mines use a system of passes to transfer by gravity the ore from the upper levels of the mine to the crushing and hoisting site. In a majority of cases, passes control ore flow in these openings. Often subject to blockage, these passes involve safety risks to workers during clearing operations. This study evaluated the effectiveness of various types of ore passes most commonly found in the Quebec mining industry, together with the dimensioning rules proposed in literature. This report describes these evaluations. It is accompanied by an ore pass design guide aimed at mining engineers, to help them develop and implement safer systems adapted to the particular needs of each mine.
