FIELD: mining.
SUBSTANCE: in the test bench for study of effect of explosion products on a step of explosive wells which comprises a high pressure chamber closed from above by a cover with a membrane connected to the explosive well simulator designed as a pipe according to the invention, the lower part of the explosive well simulator is also fitted with the starting section with the spring starting arrangement for forced destruction of the membrane at the time of achievement of the pre-set pressure in the high pressure chamber.
EFFECT: providing of pre-set air pressure on the stem in the explosive well simulator by forced destruction of the membrane.
