Deep Mining A Rock Engineering Challenge SpringerLink

Apr 13, 2019· Increasing demand for metals caused by global economic growth and exploitation of shallow mineral deposits forces mineral extraction to go deeper. A direct consequence of this development is an increase in rock pressurerelated mining problems. The role of rock engineering in the design and operation of deep mines is discussed in detail. Critical issues are the rock fracturing

Selection of practical bench height in open pit mining

The bench height is a minerelated parameter that can be studied using a simple geometrical model of the deposit. By changing this parameter individually, while the depositrelated parameters (such as ore bench heights in the final pit design. In the proposed method, the ore reserve is entirely considered as a hypothetical large block with

Fundamentals of slope design Keynote address at Slope

Consider the very simple case of a wedge failure in a 15 m high open pit mine bench. As illustrated in Figure 2, the wedge slides along the line of intersection of two planes and the back of the wedge is defined by a steeply dipping tension crack. It is assumed that water pressures act on the sliding surfaces and in the tension crack and that

Crown pillars QueensMineDesignWiki

When designing underground mines, it is necessary to consider a crown pillar, which provides a barrier between the surface activity and underground. A crown pillar, defined as a rock mass situated above an uppermost stope of the mine, can be one of two types a surface crown pillar and crown pillar between open pit and underground [1] .

Underground Ramp Design Parameters </h3>IntroductionRamp UsePlacement and Ramp TypeRamp GradeCrossSectional DimensionsIntersectionsAppendixGrade is a very important design parameter to consider. It has a substantial impact on both capital expenditure and operating cost. Generally speaking, more capital spent will result in lower overall operating costs and vice versa. The typical gradient range for underground ramp systems is between 10% and 15.5% (1), although in some high volume mines with larger trucks (such as is often the case in Australia) (1), they can be in a range more similar to that of open pit haul roads, 6% to 10% (3).
