Hanging Wall Mining

In fault block below is called the footwall.

Hanging wall mining. Drilling the pilot holes and accurately mapping the vein then enlarging the pilot holes to predetermined sizes to recover the ore. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. Three under ground excavations are designed including footwall de cline hanging wall decline and stope excavation. The fault strike is the direction of the line of intersection between the fault plane and earth s surface.

The dip of a fault plane is its angle of inclination measured from the horizontal. Hanging wall and footwall the two sides of a non vertical fault are known as the hanging wall and footwall. Roughly half way between the hanging wall and footwall of the vein and then bring the pile top drill rig in to enlarge that. The underside of the wall rock overlying a vein or bed of ore compare footwall def.

The hanging wall is the left. Remove previously blasted material muck out round scaling removing any unstable slabs of rock hanging from the roof and sidewalls to protect workers and equipment from damage installing support or and reinforcement using shotcrete etceteras drill face rock load explosives and blast explosives. It includes an explanation of the different products. The topside of a vein or orebody along the dip.

The process sustainable mining by drilling smd is divided into two campaigns. Delineation ore body is called the footwall. A mass of rock overhanging a fault plane. The distance be tween stope to footwall decline d1 set fixed as 20 m.

To start the mining the first step is to make the path to go down. This video provides a basic description of the long wall mining method for extracting coal underground. The declines geometry both on foot wall and hanging wall are 4 2 m width and 4 8 m height. The hanging wall occurs above the fault plane and the footwall occurs below it.

Meanwhile standard stope geometry is 5 m width and 5 m height.
