Mercury Contamination from Historical Gold Mining in ...
· Monitors (or water cannons, fig. 1) were used to break down placer ores, and the resulting slurry was directed through sluices (fig. 2). As mining progressed into deeper gravels, tunnels were constructed to facilitate drainage and to remove debris from the bottom of hydraulic mine pits. The tunnels also provided a protected environment for sluices and a way to discharge processed .
Glossary of Mining Terms
A. Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Heap Leaching of Gold and Silver Ores
· The mining, ore preparation. and stacking methods should vary. Where runofmine ore is to be leached it may be blasted heavily; fine crushed ore that is high in clays may be mined with minimal stockpiles. The environmental requirements for reclamation and closure vary widely and should be considered during the design phase of the heap. In operations, there are some common problems .
Underground Mining Transportation Systems
applicable to the ore deposits being mined, the mining methods employed and the mine layout. 1. Introduction Transport developments followed two distinct routes in each of the major functions, namely the movement of ore/coal, persons, materials and equipment. Ore/coal transport has either been by locomotivehauled mine cars, belt conveyors or rubbertired trucks. The transport of persons ...
Open Cut and Underground Mining | iMINCO
Underground Mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use. A tunnel, called a decline, is created to allow workers and machinery to reach the loion of the minerals. Stope mining is used for most hard rock mining of minerals such as copper, silver, lead and zinc.

DESIGN OF MINE SHAFT ELEVATOR
mining". Contrarily, if an ore body is very deep, then there is supposed to be a mine shaft. Even though that costs even more, an opencast mining would not be used for that deep excavations and that process is called "deep mining". When it comes to design of a mine shaft, there are two options: circular shafts and horizontal shafts (Figure 1, Figure 2). Circular shaft is the most commonly ...
