Microseismic monitoring for slope stability - Mining3

Microseismic monitoring techniques are used to assist in characterising the rock/structure disturbance behind the slope before movements on the surface can be visualised or detected. This information is crucial for slope assessment and potentially warning of impending collapse.

Mine dewatering techniques - SlideShare

Nov 23, 2013 · Underground Mine Dewatering Techniques • In underground mines, the conventional approach is to allow groundwater to enter the workings, effectively using the mine itself as a drain • The water entering the mine is passed along roadways (by pumping or gravity) to a deeper part of the mine (sump) or shaft bottom, to be pumped out via shaft or ...

Coal, Kentucky Geological Survey, University of Kentucky

Underground Mining. Underground modes of access include drift, slope, and shaft mining, and actual mining methods include longwall and room and pillar mining. Drift mines enter horizontally into the side of a hill and mine the coal within the hill. Slope mines usually begin in a valley bottom, and a tunnel slopes down to the coal to be mined.

Geotechnical Engineering: Slope Stability

They are certainly major factors in cut slope stability and in the stability of fill slopes involving both "internal" and "external" slope failures. The effect of water on cut and fill slope stability is briefly discussed below. • Importance of Water Next to gravity, water is the most important factor in slope stability. The effect of

The invention discloses a method for treating a dump slope of a surface mine. The method comprises the following steps of: treating to ensure that the side slope grade is (1:1.5)-(1:3), wherein if the slope is cohesive soil, the side slope grade is 1:1.5; if the slope is gravel, the side slope grade is 1:3; if the slope is other soil, the side slope grade is (1:1.5)-(1:3); building platforms ...
