Abstract

W zamkniętej komorze (1) podnosi się ciśnienie pompą (12) i temperaturę cieczy grzałkami (2) do wartości przewidywanych na głębokości planowanej eksploatacji węgla w kopalni. Następnie prowadzi się osobno wybuch zapalnika (b) oraz osobno wybuch ładunku (a) materiału wybuchowego z zapalnikiem (b), zawieszonych na trzpieniu (4) osadzonym w pokrywie (3) komory (1). Zmiany ciśnienia cieczy rejestrowane są komputerowo oraz przedstawione na wykresach przebiegu wybuchu zapalnika (b) i przebiegu wybuchu ładunku (a) materiału wybuchowego z zapalnikiem (b). W końcowym etapie porównuje się maksymalne ciśnienia z wybuchu ładunku (a) materiału wybuchowego i z wybuchu zapalnika (b) materiału wybuchowego i ustala, że jeżeli maksymalne ciśnienie wybuchu ładunku (a) materiału wybuchowego z zapalnikiem (b) jest wyższe od maksymalnego ciśnienia wybuchu zapalnika (b) to badany materiał wybuchowy nadaje się do pracy na danej głębokości.In the closed chamber (1) the pressure (12) and the temperature of the liquid with heaters (2) are raised to the values predicted at the depth of planned coal mining in the mine. Then the detonator explosion (b) and the detonation of the charge (a) of the explosive with the detonator (b) are carried separately, suspended on the stem (4) mounted in the cover (3) of the chamber (1). Changes in liquid pressure are recorded by computer and are presented on the charts of the igniter explosion process (b) and the charge explosion process (a) of the explosive with the igniter (b). In the final stage, the maximum pressure from the explosion of the charge (a) of the explosive and from the explosion of the igniter (b) of the explosive is compared and it is determined that if the maximum explosion pressure of the charge (a) of the explosive with the igniter (b) is higher than the maximum explosion pressure of the igniter ( b) the tested explosive is suitable for work at a given depth.
