Informed mine closure by multi-dimensional modelling of tailings deposition and consolidation

فصل «Informed mine closure by multi-dimensional modelling of tailings deposition and consolidation» از کتاب «Proceedings of the International Conference on Mine Closure» بر «ریسک، قرارداد و تعطیلی معدن» در حوزه «مدیریت صنعت مس و معدن» تمرکز دارد. محتوا مبانی علمی، روش‌های فنی و پیامدهای عملی موضوع را به‌صورت منسجم توضیح می‌دهد. برای تحلیل بازار، ارزیابی سرمایه‌گذاری، سیاست‌گذاری، مدیریت ریسک و برنامه‌ریزی راهبردی مفید است.

This paper introduces an advanced geotechnical numerical modelling approach, which can be used to simulate the gradual deposition and large-strain consolidation of tailings in a multi-dimensional space. The findings from the modelling can be used not only to inform planning and design at mine closure but also help the management of tailings impoundments. Following a state-of-practice review of tailings consolidation modelling, the recently developed multidimensional modelling technique (the Norwegian Geotechnical Institute [NGI] model) is described in the paper, with validations against available analytical solutions and comparisons with commonly used predictions presented by Townsend & McVay (1990).
