Steeply dipping mine workings (30-70 degree dip) - If the ground surface over a mine in steeply dipping beds is nearly horizontal then the subsidence hazard boundaries on the footwall side of the mine will lie 100' beyond the extension of the footwall to the surface.
This paper presents a new risk assessment methodology for coal mine excavated slopes. This new empirical-statistical slope stability assessment methodology (SSAM) is intended for use by geotechnical engineers at both the design review and operational stages of a mine's life to categorise the risk of an excavated coal mine slope.
The coal measures, where they have been developed to the greatest extent, dip westward at an angle 30 degrees at the outcrop, but this inclination gradually decreases to the dip in the line of the main slope. The average inclination in No. 2 Mine before it closed was about 11 degrees.
Once the adjusted dip angle is known, a simple cross section can be used to project the coal seam to its surface outcrop. Several such cross sections can be used to define the coal outcrop line. However, in cross sections using vertical exaggeration to better illustrate the local topography, the dip must be converted from degrees to slope. Once

The seam is accessed via three drifts at a surface elevation of approximately 6900 feet above sea level. The seam dips toward the northeast (strike south 80 degrees east) at a rate of 5% and topographic highs exceed 8000 feet in elevation in the area. A stratigraphic dip and topographic increase combine to provide a rapid rise in overburden height.

Since down-dip mining is not an entirely new or experimental tech- nique, its range of applicability has already been fairly well estab- lished through actual use. Normal down-dip mining procedure has been to enter a coal seam from an up-dip coal outcrop and expand from there toward the dip.
The strata of the west limb are flat with dip angle of 7 0-16 0 in general, ... Long wall mining involves removal of coal from single faces, generally 80 to 200 m long with the working area protected by moveable roof supports. As the coals are extracted, these supports are moved forward so that the roof behind them collapses to form an ...

The amount of dip is determined from the amplitude of the sinusoidal trace, and the dip azimuth is the minima of the sinusoidal trace. The latter can be read off the horizontal axis of a scanner log scaled from 0 to 360 degrees (Figure 4). The azimuth of cleat in coal can also be determined where the apparent dip of cleat is not vertical from a

During the last 30 years, surface coal-mining production has increased relative to underground coal mining in many areas because of the introduction of new high-capacity mining equipment. Surface coal-mining production exceeded underground-mining production in 1975 in Indiana, Ohio, Alabama, Tennessee, and Maryland.

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.. Surface mining began in the mid-sixteenth century [dubious ...
