What differentiates Subtek™ from packaged explosives underground? Subtek™ is a bulk emulsion manufactured on-site and pumped to the hole. This reduces packaging waste, improves logistical efficiency, and allows variable energy control for precise outcomes. 

Can Subtek™ be used in wet holes or dewatered headings? Yes. The emulsion matrix offers excellent water resistance, maintaining column integrity and detonation performance in wet and dewatered conditions. 

How is energy tailored for different geological conditions? Through variable density and charge profiling. Operators can adjust energy along the hole (e.g., toe versus collar) to limit overbreak and optimise fragmentation. 

Is Subtek™ suitable for reactive ground? Standard Subtek™ is not suitable for reactive sulphide ground. For mildly reactive conditions, use Subtek™ Eclipse and consult Orica technical teams for validation. 

What delivery systems are available for Subtek™ underground? Subtek™ integrates with Orica’s underground delivery systems such as MaxiLoader™, Down-the-Hole charging, and Total Load Service, supported by Technical Services for design and execution. 

How does Subtek™ support perimeter control and reduced overbreak? Products like Subtek™ Control reduce wall damage by enabling lower energy near the perimeter and enhanced accuracy in loading. 

Which initiation systems are compatible? Subtek™ is commonly paired with Pentex™ boosters and detonator systems such as Senatel™ Pyromex, WebGen™, eDev™ II, and i-kon™, depending on site standards and design. 

What are the typical hole diameters and depths? Subtek™ formulations cover common underground diameters and can be adjusted for deep holes. Confirm site-specific limits and pump configurations with Orica. 

What safety benefits does Subtek™ offer? Engineered systems reduce manual handling, improve charging accuracy, and support consistent blast outcomes, lowering operational risk. 

How does Subtek™ contribute to sustainability targets? Bulk delivery reduces packaging waste; tailored energy reduces overbreak and unnecessary mucking, potentially lowering fuel and power consumption.
