METHOD AND APPARATUS FOR FEEDING HOSES INTO MINING BOREHOLES AND THE LIKE

摘要

A method and apparatus are described for feeding a hose having a corrugated exterior surface into a mining borehole and the like. The apparatus includes a support frame and a rotatable drive wheel having an annular groove for receiving the hose and ridges extending therefrom for meshing with the corrugated surface of the hose. An idler wheel having an annular groove for receiving the hose is disposed of the support frame to bias the hose against the drive wheel. A reversible, variable speed motor coupled to the drive wheel is provided for causing the drive wheel to rotate in a selectable direction and at a selectable speed. The apparatus is mountable on an implement used in a mining operation. The hose is couplable to a source of liquid explosive and to an inflatable wand for charging boreholes with explosive. 26
