RIOTRONIC X+
User Manual
The result screen shows detonator’s ID, delay time and sequence number actually stored in
detonator’s memory and self-test result (OK or not OK).
If detonator is OK, then BACK or F2 key leads to main menu. If there is any error, BACK or
F2 key starts another test. MENU leads to main menu and CANCEL leads to programming.
Once all RIOTRONIC X+ detonators have been checked, distribute them in the blast.
Connectors should be closed after testing to avoid any damage caused by mud. There are
more options in the test menu. They will be covered in Riotronic X+ Logger – user manual.
3.2.3. Risk assessment
A risk assessment of the whole blast operation should be performed as a first step, analyzing
risks and making sure the operators have been appropriately tasked.
Risk Assessment at a broad operational level, and more specifically focusing on the
management of blasting and explosives, provide guidance for dealing with the hazards and
potential consequences of undesired outcomes and impacts. Specific risk assessments must
also be carried out, identifying the hazards that could be presented by an individual shot,
and the controls required at each stage of the blasting process. Operational risk assessments
should also be conducted on a daily or shift change basis as relevant. Again, these exercises
must be conducted by a representative group of stakeholders.
The main areas to consider include:
(a) Planning and design – Identifying the hazards and controls associated with specific
blast types and ground conditions, and the potential impacts on subsequent mining
activities, wall stability, environmental impact, downstream processing etc.;
(b) Bench preparation and demarcation – Identifying the hazards and controls
associated with equipment and personnel working within the blast area, including
broken ground, cavities, vehicle rollover, unsafe high-walls/low-walls, adverse slope
and crest conditions, unauthorised access, water management and interaction with
other mining processes;
(c) Priming, charging and stemming blastholes – Avoiding hazards associated with the
snap/slap/shoot of signal tube downlines, unplanned detonation in elevated
temperature and/or reactive ground, and flyrock/overpressure associated with
overloaded or under-burdened holes;
(d) Blast clearance & shotfiring – Ensuring adequate blast clearance and controls are in
place to prevent unauthorised access into the blast exclusion zone while blasting is
in progress and until after the ‘all clear’ has been given. Identifying where post-blast
