FIELD: mining.
SUBSTANCE: each layer is developed with the use of utilised vehicle tyres as a support, note that the layer height is taken not more than tyre height or divisible by its other sizes. Backfilling material is supplied to developed space with mounted tyres. The support from utilised tyres is used as shuttering at backfilling material supply. Note that the tyres are mounted close to each other and isolated from backfilling space by material capable to drain water.
EFFECT: increase of speed of layer development, increase of work performance safety, extension of method capabilities.
