New development of expert system module for a decision-making on mine stope stability in underground blasthole mining operations

Abstract

This is the first report on the research and development (R&D) project for the development of an expert system for 3D stope stability assessment, for underground blasthole mining operations with delayed backfill, at depths from 500 to 2000 m below the ground surface. A new expert system module called the stope stability assessment program (SSAP) was developed based on the data generated from a state-of-the-art 3D elasto-plastic finite element analysis developed by the Canada Centre for Mineral and Energy Technology (CANMET), heuristic rules and case histories. This module mimics the rational processes of rock mechanics experts in providing recommendations to mine operators to make decisions on strategic mine planning and feasibility studies. As a result, planning and decision-making can occur in a quick and efficient manner to minimise the risk of ground failure and optimise mining costs. Consequently, the risks regarding mine safety and productivity can be properly managed.
