ABSTRACT:
An improved mining method for a surface mine has pairs of slurry and water pipes placed from a processing area on the surface to the floor of the mine beneath the mined out material, pairs of pipes (slurry and water) are spaced along the mining trench. A slurry haulage system is connected to the water and slurry pipes at the beginning of the mining operation. As the mining progresses and the haulage system reaches its maximum capabilities, it is disconnected and connected to the next set of pipes and the first set or pair of pipes is extended the width of the mined trench. The overburden is placed on top of the pipes as the mining progresses.
