Combined Method of Coal Mining in the Opening of Shallow Layers as a Direction of Innovative Development of Geotechnology
In recent years, there has been a decline in the efficiency of coal mining by traditional methods. On the one hand, the volume of coal outside the contour of the cut, which is economically impractical for open-pit mining, is increasing. On the other hand, when using underground geotechnology, the co...
