A computer program package for predicting surface subsidence induced by underground mining operations. The development of the prediction package is based on the influence function method that is widely adopted in the major mining countries including US coal mining industry. The findings from our researches in the last 15 years on mining

The degree of potential geologic hazards depends on depth to the mine and occurrence of a rigid sandstone bed (layer) in the rock interval between the top of the mine and the surface.

Read more...Mine subsidence is the movement of the ground that can occur after underground coal mining. After coal is extracted from beneath the ground, the land above can sink and fill the hollow mine workings. This can cause tilts and strains on the ground surface. Subsidence caused by old inactive mines in New South Wales is generally localised and only ...

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.
