LAYER EXCAVATION METHOD OF MINERAL RESOURCES Russian patent published in 2008 - IPC E21C41/16 

FIELD: mining engineering.

SUBSTANCE: method includes carrying out of face entry 11,13, main 1-4 and divisional 5-10 development workings, delineating of mineral resources blocks, assembling of scouring mechanised systems in face entries 11, consistent pairwise mineral resources blocks debugging with long faces N.1, N.2 and dismantling of scouring mechanised systems in dismantling chambers 12. Face entry of the second long face 13 deepen in line of dismantling chamber 12 of the first long face at first stage. At the beginning, by the moment of broken working termination in first long face deepens the area of the second long face, and located from side of mineral resources virgin ground. After termination of broken working in the first long face, face entry of the second long face is deepen till the mined-out space, appeared while debugging of the first long face. At that length of face entry unit of the second long face, debugged after broken working termination in the first long face, is taken more than boost band width, appearing in front of the first long face bank.

EFFECT: costs decreasing connected with accomplishing of assembling-dismantling works, as well as a time cutting of their accomplishing and safety improving.
