This, in turn, makes it faster to get to the coal access with low invest, when compared to longwall mining. In room-and-pillar mining, however, only 50% to 75% of the coal reserves are utilized. Room-and-pillar mining is used to develop roadways so that the miners can prepare the coal face for longwall operation.

Compact Mining Drill Layouts. Design / Blueprint.

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

The number of entries available for ventilation vary with the mining method used and the geological characteristics of the rock strata mined. Exhaust fans are commonly used to ventilate underground coal mines. Positive-pressure fans are used infrequently-usually where the mine is close to the surface and there is leakage to the

Nord-Pas de Calais Mining Basin. 1.83. . The Nord-Pas de Calais Mining Basin is a mining and industrial cultural landscape along a 120km long coal seam in the far north of France.

Silica Exposure In Mining ; Miners often extract high-silica-content rock from the coal seam or the surrounding strata. Large quantities of silica dust can be generated during cutting and can become entrained in the ventilating air, which can carry the dust to the breathing zones of mine workers.
