2. Accessing the Platform

First-Time Login

  1. Navigate to the Platform Open your web browser (Chrome, Firefox, Safari, or Edge recommended) and go to the MineGeotech URL: https://www.mine-geotech.com.
  2. Sign In Click Login / Sign up button in the top-right corner of the page. Enter your username and password, then click submit to access the platform.
  3. Verify Access Once logged in, all modules are available. Your session will remain active until you log out or close your browser.

Important

User authentication is required to access all calculation features. Results are saved to your session and will be cleared when you log out.

Logging Out

When you're finished:

  • Click the Logout button in the top-right corner
  • This clears your session data and secures your account
  • Remember to download any results you need before logging out

3. Understanding the Interface

The left sidebar is your primary navigation tool:

Section Description
Home Returns you to the welcome page
Module A Pillar Spalling Analysis (single- and multiple-case analysis)
Module B Floor Bearing Capacity (standard and sensitivity analysis )
Module C Burst & Seismic Analysis, including Coalburst, Rockburst and Far-field Seismicity; Near-field Seismicity is coming soon
Results Access saved calculations. Up to 25 results are automatically saved across all modules, with a warning when storage is almost full or full.
User Manuals Detailed technical documentation for each module

Tip

Results sections are grayed out until you run your first calculation. They become active automatically once you complete an analysis. When the 25-result limit is reached, calculations can still run but new results will not be saved. Export important results and delete older results to make space for future runs.

4. Module Overview

Module B Floor Bearing Capacity

Purpose

Calculate the ultimate bearing capacity of weak floor strata to prevent floor heave and maintain roadway stability.

  • Groundwater conditions

Outputs

  • Ultimate bearing capacity
  • Allowable bearing capacity with safety factors
  • Probability distributions (Monte Carlo)

Module C Burst & Seismic Analysis

Module C contains three available calculators with different purposes. Select the workflow that matches the event being assessed; their inputs and outputs are not interchangeable. A fourth, near-field seismicity workflow is planned.

Coalburst Assessment

Available

Models coal ejection driven by released strain energy and coal-gas energy, with optional bolt-and-mesh support.

Typical inputs
  • Excavation and ejected-coal geometry
  • Coal density, cleat porosity and Langmuir properties
  • Gas pressure, gas content, temperature and released elastic energy
  • Optional bolt and mesh properties
Key outputs
  • Coal displacement and ejection velocity
  • Bolt elongation, bolt force and mesh tension
  • Velocity hazard category and support status

Rockburst Assessment

Beta

Provides a simplified adaptation of the Coalburst framework for hard-rock ejection using released elastic energy and a reduced input set.

Typical inputs
  • Excavation and ejected-rock geometry
  • Rock density, fracture porosity and thermal properties
  • Released elastic energy
  • Optional bolt and mesh properties
Key outputs
  • Rock displacement and ejection velocity
  • Bolt elongation, bolt force and mesh tension
  • Velocity hazard category and bolt status

Far-field Seismicity

Available

Estimates seismic energy transmitted from a distant circular fault-slip source to a spherical ejection target at an excavation.

Typical inputs
  • Horizontal distance, elevation difference and fault dip
  • Source radius, seismic energy and event duration
  • Target radius and P- and S-wave velocities
Key outputs
  • Transmitted P-wave and S-wave energy
  • Total energy intercepted by the target
  • Transferred energy density at the target

Near-field Seismicity

Coming soon

This planned workflow will address seismic sources located close to the excavation, where near-source interaction requires a separate assessment approach.

Current availability

No Near-field Seismicity calculator or input form is currently offered. Use the Far-field workflow only when its source-to-excavation assumptions are appropriate.

Coalburst and Rockburst velocity classification

The following velocity-based classification applies to the Coalburst and Rockburst assessment results, not to the Far-field Seismicity energy-transmission result.

Ejection Velocity Impact Level
< 3 m/s Low impact
< 7 m/s Moderate impact
< 11 m/s High impact
> 11 m/s Severe impact

5. Getting Started with Calculations

General Workflow

  1. Select Your Module Click the appropriate module (A, B, or C) in the home page or sidebar and read the module introduction if unfamiliar.
  2. Understand Input Requirements Review parameter definitions, check units (clearly marked in labels), and note typical value ranges. Explanations of the parameters can be found in .
  3. Enter Data
    • New users: Click "Example" button to load sample data
    • Experienced users: Enter your site-specific parameters
    • Multiple cases processing: Download CSV template and upload your data
  4. Validate Inputs Check for red error messages, ensure all required fields are filled, and verify units are correct.
  5. Calculate Click the "Calculate" button and wait for processing (typically 1-30 seconds). Completed results are automatically added to Saved Results while storage space is available.
  6. Review Results Go to the Results section in the sidebar to examine tables and charts, and compare them with your design criteria. Your inputs are retained on the Inputs page, so you can switch between Inputs and Results to adjust values for parametric studies.
  7. Export Results Download as Excel (raw data for further analysis). Save images of specific charts.
  8. Iterate if Needed Use "Reset" button to clear inputs, modify parameters and recalculate.

Tips for Success

Data Preparation

  • Gather all required parameters before starting
  • Use consistent units throughout
  • Document data sources for traceability

Using Example Data

  • Excellent for learning the interface
  • Shows expected value ranges
  • Helps understand output formats

CSV Import (Modules A, B and C)

  • Always download the template first
  • Match column/row headers exactly
  • Use consistent decimal separators
  • Check file encoding (UTF-8 recommended)

Result Interpretation

  • Read the accompanying explanations
  • Compare calculated safety factors to industry standards
  • Consider uncertainty in input parameters
  • Consult user manuals for detailed methodology

Saved-result storage limit

Your account automatically saves up to 25 results across all modules. A warning message appears when your saved-result storage is almost full or has reached the limit. Calculations can still run when storage is full, but further results will not be added to Saved Results.

To keep important work and make room for future results, first export the results you want to retain. Then delete one or more older results from All Saved Results. New calculation results can be saved again after space is available.
