FIELD: blasting.
SUBSTANCE: tamping includes upper and lower parts, separated by the buffer gap of polystyrene foam. The lower part is the filling of inert bulk materials over the air gap. At the top of tamping on the buffer gap a cone for example of hardening materials is mounted with its end pointed upwards. Next to the top of the well the charging inert material is placed. Between the cone and the walls of the well the large gravel is placed.
EFFECT: improved reliability, lower costs.
