Abstract
The invention concerns a blasting system (1) configured for explosive material charging in a borehole (3). The system (1) comprises a detonator support device (5) configured to be inserted into the borehole (3) by means of a charging hose (7); a main body (9) of the detonator support device (5) comprises a channel (8) oriented along a main body centre line (CL) extending along the borehole extension during said explosive material charging; an openable cover device (14) covering the channel (8) is configured to come into contact with the charging hose (7) in motion for pushing the main body (9) along the borehole (3), wherein the charging hose (7) in motion is configured to open the openable cover device (14) whilst a stopping arrangement (13) stops the main body (9). The invention also concerns a method of explosive material charging in a borehole (3) by means of the blasting system (1).
