The article discusses the use of the "Alimak" complex for mining ore bodies "Sub-level chamber system with layer by layer breaking of ore by deep wells and delivery by explosive force". Cleaning excavation is carried out in a retreating order from the flank of the ore body. The block is mined by paired cuttings from drilling risers. The cleaning cycle when using the Alimak complex consists of breaking ore in cuts and the sum of operations to move the monorail behind the advance of the working face along the strike of the vein.
The use of the "Alimak" complex is justified by the fact that the productivity of the treatment unit or excavation unit increases. It also reduces the volume of cutting operations due to the use of deep wells for breaking and delivering ore to the bottom of the block by the force of the explosion. The height of the treatment block can be developed up to 120 m according to the uprising of the vein, which makes it possible to accept the distance between the horizons up to 120 m.
