Rockmass response to mining

Posted on 8th September 2021 at 12:00am

The key to optimised mine plans is to understand how ground conditions are likely to evolve during extraction. GMD works with clients to understand the ground reaction based on the current mine plan, including extraction rates and methods. We integrate seismic and other monitoring system data (where available) and numerical models to create virtual simulations of existing and proposed mining block development. Whether on the scale of an individual mining block, or the whole mine, our data analysis techniques allow large volumes of data to be targeted as a key part of your long- term mine design optimisation strategy. Our philosophy places this information back into the mine plan to produce optimised design solutions that saves cost and time and ensures that your critical infrastructure remains serviceable over its expected life.

Observations from site visits form the basis of a comprehensive ground monitoring strategy and GMD personnel are field- trained to observe changes in rockmass quality over time. Wherever possible we compliment our traditional data collection programs by capturing the study area using the latest photogrammetry and laser scanning technology.

GMD designed ground support systems always include provision for excavation monitoring equipment able to record physical data such as displacement and force, in proximity to excavation limits. This information can be used in conjunction with numerical modelling to create safe working protocols.

Whether you need advice on how to design and implement monitoring systems, training on how to maximise the benefit of an existing system, or the interpretation of data to ease the workload of an existing department, GMD will provide a cost effective solution.
