Mine Shaft Sinking Costs

Mine Shaft Sinking Costs

Costs of sinking a mine shaft vary with the size and depth of the shaft; nature of the rock (the ease with which it can be drilled and broken, and the nature and amount of support required); amount of water that must be handled, speed of sinking, organization of the work, and the equipment employed; and labor and other local conditions. The effect of most of these factors upon costs is self .
