Hot and reactive ground risk reduction
Minimise risk and improve safety in reactive environments.
Proven solutions to manage complex ground chemistry and elevated temperatures.
Proven solutions to manage complex ground chemistry and elevated temperatures.
Hot and reactive ground presents serious safety and operational challenges due to the chemical interaction between sulphide minerals and ammonium nitrate.
Orica’s solutions are designed to manage ground that is hot, reactive, or a combination of both, by helping sites reduce risk, maintain productivity and meet compliance requirements.
Our approach combines tailored explosive formulations, expert technical support and a proven framework to ensure safe and reliable blasting in even the most complex conditions. Our consultation process begins with identifying hazards, followed by tailored blast designs, product selection and operational controls.
This framework mirrors our industry-leading fume and nitrate risk reduction frameworks, integrating technical solutions, training and best practices to reduce environmental and safety risks. By combining field data, expert support and a specialised product range, we help customers improve safety, maintain productivity and meet regulatory requirements in high-risk environments.

Further insights
Further insights
What is reactive ground? Reactive ground contains sulphide minerals that can chemically react with ammonium nitrate, potentially causing heat build-up and explosive decomposition.
What is hot ground? Hot ground refers to blastholes or rock that have elevated temperatures, often due to natural oxidation of sulphides or geothermal activity.
Can ground be both hot and reactive? Yes. Combination ground presents the highest risk, where elevated temperatures and reactive chemistry can accelerate dangerous reactions.
How does Orica manage these risks? We offer tailored explosive formulations, technical audits, and a proven framework to safely manage hot, reactive or combination ground.
Is this solution suitable for underground mining? Yes. Our approach is designed for both surface and underground operations, with products and support adaptable to site-specific conditions.
