Sentence examples for mining width from inspiring English sources

The depth of the failure zone is strongly dependent on the mining width.

The influence of lithology of overlying rock, mining width and mining height on the void distribution in collapsed zone is revealed.

Open image in new window Fig. 6 Strain profiles in major cross-section for varied mining widths (W) under mining height of 5.0 m and surface subsidence factor of 0.3.

It utilizes characteristics of the coal seam/s and associated underlying and overlying strata (geologic, hydro-geologic, and geometric such as seam pitch, anomalies), mining operations (panel width, panel length, mining rate, etc)., regional subsidence characteristics (angle of draw, angle of break, tensile and compressive strain, etc)., and surface topography to achieve this.

GOROL KADJE, Burkina Faso, 11 June 2014 – In the northern reaches of Burkina Faso, not far from Dori, 15-year-old Boureima Hawma Boukoum is lowered down a mine shaft the width of a manhole.

The strike length and slope width of the mining working face will determine the lifespan of the bed separation.

By incorporating Fig. 5 into surface subsidence prediction, horizontal strain profiles are generated for varied panel widths at the mining height of 5 m using complete backfill with subsidence factor of 0.3 (Fig. 6).

The width of the coal mine is 3 8 km from south to north, and the length is 10 13 km from east to west, the total area is 47.3 km2.
