Predictive analytics for Air & Ground Vibrations

MineExcellence Air & Ground Vibrations Predictor software for maintaining optimum blast vibration levels.

Drilling and blasting are necessary steps in any mining field to break and excavate rocks. A majority of energy from explosives is lost by ground vibration, noise, air blasts, etc. Moreover, noise and vibration, caused by blasting operations can have an impact upon neighbouring premises. Proper control of blasting practices is therefore necessary to ensure both the safety of employees and the protection of the community from adverse effects.

Predictive analytics is the use of data, statistical algorithms and machine learning techniques to identify the likelihood of future outcomes based on historical data. The goal is to go beyond knowing what has happened to providing a best assessment of what will happen in the future. MineExcellence softwares offer intelligent approach and necessary tools to predict and control air & ground vibrations in mines and subsequently redesign the blast in order to avoid possible damages.

Business benefits of using predictive tools for Air & Ground Vibrations

  • MineExcellence Air & Ground Vibrations Predictor tools helps in assessing vibration levels in the area surrounding the blast.
  • The predictors support and improve compliance with blasting related planning conditions and contribute to improve blast performance and blast design.
  • It provides minimum instantaneous charge (MICs) to the operator that ensures compliance with vibration level restrictions by design rather than by accident.
  • The vibration software allows analysis of financial and environmental risks, hence optimizing costs and maximizing efficiency.

How does it work?

Ground vibrations are influenced by a number of parameters like rock mass, explosive characteristics, blast design, etc. The prediction model is based on standard Square root scaled distance method, which uses statistical analysis from many blasts. Users may adjust the exponent, coefficient, constant, number of contours, etc and determine the optimum charge and distance values required for safe blasting. The prediction software produces decibel contour plans to a scale, which can be overlain over aerial photographs, maps or plans. Once charge, distance and timing plans have been created, engineers have a set of tools at their disposal to assess the overall blast performance, and ensure that ground vibrations or Sound Intensity estimates are well within limits set down by the regulatory authority.

The predictive softwares developed at MineExcellence provide the following features:-

  • Graphical representation of site/sonic law generation with regression analysis and coefficient values.
  • Satellite and terrain view of contour plans for both Air and Ground Vibrations.
  • Estimates Ground vibration level (in PPV) / Sound Intensity level (in dbl) based on charge and distance.
  • Generates blast reports.
