BENCH TO STUDY LOCKING CAPABILITY OF BLASTHOLE TAMPING

摘要

FIELD: blasting.;SUBSTANCE: bench comprises a high pressure chamber closed with a cover on top and a metering complex. A ball valve is mounted into a cover, which connects the high pressure chamber with a blasthole imitator installed on the cover and made in the form of a pipe with notches in the lower part. Notches imitate cracks in rock. Slots in the upper part of the pipe imitate damaged rock massif. The metering complex comprises sensors of pressure and a electrometric sensor of shift value.;EFFECT: modelling of blasting products influence at blasthole tamping.;1 dwg
