Charge Standards

Charge standards define the default ways that holes will be charged. Charge standards control how blast hole conditions (such as depth, water, mud, temperature, reactivity and geological intersections) impact the location and type of decks to be loaded. There are two types of charge standards in DataBlast Pro:

1. Conventional Charge Standards
2. G-Blast Charge Standards—Design charging for holes that are intersected by geological strata.

Charge Standard Blast Types

Charge standard blast types are used when configuring conventional charge standards and G-Blast components.

Z Timing Zones

Z timing zones are used in electronic detonator sequencing to apply deck, or vertical (Z), timing.

The colours are used in the firing simulation display. See Run a Firing Simulation.

Charge Rules

Charge rules are derived from charge standards. When applied to charge patterns, charge rules create hole-specific load definitions describing all the explosives and inert decks and the in-hole initiation system for all holes in the charge pattern. Local copies of charge rules are saved against charge patterns to prevent subsequent changes altering the charge detail. Charge rules are drill-diameter specific. This means that a charge pattern needs to have a consistent hole diameter. This is a safety requirement because minimum stemming for flyrock control is directly related to the blast hole diameter.
