Mine Seismicity

The Mine Seismicity module provides tools for the analysis and interpretation of seismic data and management of seismic hazard.

Key Apps

Grid Based Analysis

📄

7 artículos

Short-term Response Analysis

📄

This app is for the analysis of short-term seismic responses following a trigger. A trigger is a single event or blast that may result in a temporary increase in seismic activity while a response is clustered seismicity following a trigger.

Large Event Analysis

📄

Analysing seismicity around large events

Hazard Assessment

📄

The grid-based seismic hazard assessment app assesses the current seismic hazard for the mine based on the recent seismic history.

Fault-based Analysis

📄

Analyse seismically active faults

Omori Analysis Tools

📄

System Design

📄

This app is used for analysing the seismic system design. It is set up with various tools to assess system sensitivity, location and mechanism quality.

General Setup

📄

Survey Setup

Mine Geometry Models

📄

Stope, cave and development geometry is a fundamental aspect of most geotechnical analysis. Mine geometry also varies over time and capturing these changes is critical in any back analysis or numerical modelling that investigates stability or monitoring parameters over time. This is a utility app to create models of mine geometry that can be exported to facilitate a wide range of applications such as:

Plane Fitting

📄

The plane fitting app provides a tool for fitting a plane through selected seismic events.

Seismic-Production Balance

📄

The Seismic-Production Balance app focuses on investigating the link between seismicity and production, specifically the balance between the two.

Rockburst Damage Potential

📄

This app is based on the Rockburst Damage Potential (RDP) system developed by Dan Heal (2010). This app provides an environment to edit the E1, E2, E3 and E4 components of the RDP system as well as to display and interrogate these components, the excavation vulnerability potential (EVP), the PPV factor and the RDP.

These apps integrate with mine geometry and other mXrap utilities for real-time data visualisation and analysis.

Supported Data Types

• Seismic Events and Sensors: Specific data export from IMS and ESG systems needed. Contact mXrap support for more information
• Blasting Data: Time and location of production and development blasting
• Surveys: DCF/VDCL, DXF, DTM, STR, ONR, INP, STL, TR, PT
• Moment Tensors: Import solutions

For full details, usage, and additional tools, refer to the app specific documentation and mXrap training programs.
