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 one hand, volume outside contour cut, which is economically impractical for open-pit mining, increasing. other when using underground geotechnology, cost production exceeds performing operations open this due to differences factors operation pit and mine. This circumstance determines use open-underground technology reserves as an actual promising direction. article describes methodological approach based on technological schemes preparation treatment powerful shallow seams, justification parameters combined geotechnology with coordinated balanced development distribution beyond limit pit, excavation sites directly from its workings coordination capacity speed their development. Its application will increase complex without additional environmental burden provide increased return investment.
