Theory And Limits Of Slope Hoisting Systems ? Introduction

Many mines, in particular coal mines, use inclines or slopes as an access to seam or seamlike deposits which outcrop at or close to the surface. In general, from the surface or from a certain depth, inclines or slopes follow the dip of the deposit with length up to 30,000 feet and by that going under an overburden cover of several thousand feet. The common outbye transport system for mine products is the conveyor. Material and men to be transported down into the mine are handled by rope driven systems when the angle of inclination exceeds the employment of locomotive traction. The transport volume can be sizeable and reach 200 to 300 tons of material and 500 men to be handled daily in a medium size coal mine with a production of 10,000 tons ROM.
