Nowadays, most modern underground mines use backfill as an integral part of their mining methods. For precious and base metal mines, this backfill may be prepared from waste rock (crushed, screened or unscreened) and/or tailings (total or classified). Backfill is used in the mining industry for several purposes such as for ground stabilization/control, extracting ore from adjacent or under another stope, extending the life of the mine and lowering the cost of mine closure. There are three main types of filling techniques used in the mining industry; cemented hydraulic fill (CHF), cemented rock fill (CRF) and cemented paste backfill (CPB). Depending on the need for ground stabilization and solid waste management, there are also composite backfills that are a combination of tailings and crushed waste rock: the cemented aggregate fill (CAF) which is a mixture of CHF and aggregates, and the paste aggregate fill (PAF) which is a mixture of CPB and aggregates. However, the backfill can perform only if the mixture is designed correctly, transported properly and poured in the open stope according to the initial design strategy and cured as planned to achieve its required strength. This Special Issue aims to bring together practical solutions for underground mine backfilling systems, including, backfill mix design, physical and hydro-mechanical properties and behaviors, rheology and transport, underground placement and self-weight consolidation, long-term properties, stability analysis, experimental studies (lab and in situ), physical modeling, analytical solutions, constitutive modeling and numerical modeling of cemented mine backfills. We welcome original and state-of-the-art papers covering all these aspects.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
