Eliminate CMRR Calculation Errors & Inconsistencies
Transform your coal mine roof stability assessments from error-prone spreadsheets into reliable, consistent, and repeatable workflows. CMRR-io ensures calculation accuracy, standardised methodology, and gives you confidence in your results.
Designed for Mining Geotechnical Engineers
CMRR-io simplifies the complex process of coal mine roof stability analysis, helping you make safer, data-informed decisions.
Project Workspaces
Create projects to structure and store your CMRR analyses more efficiently across your site/organisation.
Automated Calculations
Do away with clunky and error-prone spreadsheets. Eliminate manual errors and save time with automated, accurate calculations.
Duplicate CMRR Scenarios
Easily perform multiple scenarios for the same CMRR analysis (e.g., different bolt lengths for stone & coal roofs) with a single click.
CMRR Analysis Workflow Steps
Add Roof Units
Define your roof rock mass units with geological, geomechanical, geophysical & hydrogeotechnical data.
Calculate CMRR
Easily duplicate CMRR analyses to assess multiple scenarios (e.g., 1.8 & 2.1 m bolt lengths for both stone & coal roof scenarios).
Audit Analysis
Review and validate CMRR calculations, ensuring accuracy and identifying potential errors or inconsistencies.
Share & Export
Review results, export PDF/CSV reports & collaborate with your team.
CMRR Analysis in the Cloud
Say goodbye to complex spreadsheets and isolated data sets. CMRR-io brings sophisticated Coal Mine Roof Rating analysis to a user-friendly, collaborative platform.
From Bolt Length to Seam Type
Query any dimension across your CMRR analyses
CHART-io is completely free and can be used with CMRR-io. No additional licences, no hidden fees.
Compare roof ratings across seams, locations, or bolt configurations with intuitive filtering and grouping.
- Visualise how different bolt lengths or roof types affect CMRR ratings. Spot optimal configurations at a glance.
- Filter by seam type, depth, or geological conditions to understand spatial variations across your mine.
- Export publication-ready charts for mine planning documents and safety reports.
