Driving an Underground Mine Adit: Methods & Equipment …

Track is ordinary steel rail of proper weight for the service to which it is put or is to be put later and is laid on the adit grade. For locomotive haulage one-fourth to one-half percent upgrade to the face has been found most satisfactory. If the principal function of the adit is for drainage rather than haulage, steeper grades may be preferable.

Underground Mining Methods

The choice of an underground mining method depends on a range of factors and these include; the size and shape of the deposit, the orientation or slope of the deposit, the depth of the deposit, geological structures, characteristics of the ore and the surrounding rocks and issues with gas and water. In combination, these factors allow us to determine an appropriate …

Underground Mining Methods of Copper

The method of starting stopes on the motor-haulage level was somewhat different than on the upper levels although the size of stopes and pillars was the same. Main or Motor-Haulage Level. Motor drifts were driven on the motor-haulage level, spaced at 50-ft.; centers, and parallel to the main drifts forming the boundaries of the block.

Minerals | Free Full-Text | Alternative Process Flow for Underground …

As the near surface deposits are being mined out, underground mines will increasingly operate at greater depths. This will increase the challenges related to transporting materials from deeper levels to the surface. For many years, the ore and waste transportation from most deep underground mines has depended on some or all of the following: truck …

Fundamental behaviours of production traffic in underground …

All underground mines face the challenge of productively transporting ore to the surface for processing. Shaft hoisting is often the most efficient means of moving the ore, which is normally blasted rock, but in some instances (especially in shallow mines) the high cost of shaft-sinking is not justified [1], [2].In these and other specialized cases, the burden of ore …
