Stope design is a core discipline within mining engineering. This study analyzes the current state-of-the-art of stope through survey addressed to industry professionals. In research dominance empirical methods has slowly shifted towards numerical methods. Recent advancements have mostly focused on development optimization algorithms. The consisted 19 questions and was distributed experts via e...

The sublevel open stoping with backfill method has recently been widely used in underground metal mines. primary CPB stope is frequently affected by blasting the secondary ore stope, leading to collapse and dilution, which become a common problem received widespread attention. Numerical simulations are carried out present work, 1/4 numeral model consisting of built. divided into four layers on ...

Production scheduling in underground mines is still a manual process, and achieving a truly optimal result through manual scheduling is impossible due to the complexity of the scheduling problems. Among the underground mining methods, sub-level caving is a common mining method with a high production rate for hard rock mining. There are limited studies about long-term production scheduling...

e-Readiness assessments, for countries and organizations, are becoming of increasing importance, as they specify the current states from which planning for ICT “information and communication technology” toward supporting sustainable development, should start. This paper is concerned with providing an approach, based on the STOPE “strategy, technology, organization, people, and environment” fram...

Approximately more than 90% of all coal production in Iranian underground mines is derived directly longwallmining method. Out – of – seam dilution (namely 20–30%) is one of the essential problems in these mines.Therefore the dilution can impose the additional cost of mining and milling. As a result, recognition of the effectiveparameters on the dilution has a remarkable role in ind...

In a large underground iron mine (over 2000, 000 t/a) in China, volume of mined void could not be filled time, which posed threat to the working face. Physical and numerical models were used investigate stability sandwiched between backfills. Digital image correlation (DIC) method was employed physical model calculate deformation field roof Stress meters multi-point borehole extensometers insta...
