Detonator support device for charging a blasthole, blasting system, method of preparing a detonator support device, explosive material charging vehicle and data medium

A blasting system configured to be charged in a borehole, the system comprising:

• a first detonator support device configured for internally supporting a first elongated detonator unit;
• the first detonator support device exhibits an upper end and a lower end and comprises a first elongated sidewall hingedly coupled to a second elongated sidewall via a hinge member,
• a latching member of the first detonator support device is configured to secure the first elongated sidewall to the second elongated sidewall in a closed state,
• a first cord clamping surface of the first elongated sidewall is configured to come in position opposite a second cord clamping surface of the second elongated sidewall in said closed state for engagement with a first cord member,
• an exterior of the first or second elongated sidewall is formed with a concave elongated recess extending along a prolongation of the first or second elongated sidewall, the concave elongated recess is configured to encompass a charging hose used for charging the borehole with the first detonator support device, the system further comprising:
• a first holding device configured to engage the borehole and carry the first detonator support device, and
• a second detonator support device being engaged to the first cord member at a distance from the first detonator support device.
