These articles have been peer-reviewed and accepted for publication in IJMME, but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

  • Storing energy in disused underground mine voids: comparing pumped water- and compressed air-based technologies   Order a copy of this article
    by Friederike Kaiser, Frank Winde, Ewald Erasmus 
    Abstract: Large scale energy storage is becoming ever more important for balancing loads due to increased intermittent electric energy supply from wind and solar power plants. This paper explores how abandoned mine voids can be utilized for this purpose comparing the technological and economical suitability of two different technologies: underground pumped hydro energy storage (UPHES) and compressed air energy storage (CAES). By integrating these technologies into post-closure development concepts mine voids can be prevented from becoming environmental liabilities thereby averting costs associated with the indefinite pumping and treating of polluted water emanating from flooded mines. Apart from differing in construction costs, profitability, energy storage capabilities and grid-related flexibility each technology also requires different geological conditions that are to be considered when selecting the best suited one for a specific mine.
    Keywords: CAES; pumped hydro energy-storage; underground mine void; feasibility; energy storage efficiency; economic viability; post-mining development.

  • STABILITY ANALYSIS OF UNDERGROUND STOPE PILLARS USING THREE DIMENSIONAL NUMERICAL MODELLING TECHNIQUES   Order a copy of this article
    by Sreenivasa Rao Islavath, Debasis Deb 
    Abstract: An underground chromite deposit of strike length 290 m, width 20 m and having dip of 10 degrees with horizontal is bounded between the county rock of weathered serpentinite, serpentinite, quartzite and pyroxenite and is planned to be extracted by sub level open stoping method. The portal of the decline and shaft are located in the foot-wall of the orebody. The stope dimensions are to be determined for safe extraction of chromite ore body. For this purpose, three dimensional finite element method is adopted to develop the stope model along with decline and shaft. This study establishes the suitable pillar dimension, length and width of stope and roof bolting based on development of stresses, displacements and yield zone around the excavations.
    Keywords: Finite element model; Stope pillars; Rib pillars; Drives; Decline; Principal stress and Safety factor.

  • Energy Consumption Prediction of Gang Saws from Rock Properties in Carbonate Rocks Cutting Process   Order a copy of this article
    by Alireza Dormishi, Mohammad Ataei, Reza Khalo Kakaei, Reza Mikaeil 
    Abstract: Performance measurements of gang saws were conducted on 12 different carbonate rocks in marble factories located in Iran. Rock samples were collected from the factories for laboratory tests. Uniaxial compressive strength, Young modulus, Mohs hardness and Schimazeks F-abrasiveness factors were determined in the laboratory. Ampere consumption and rock properties were evaluated using linear and nonlinear regression analysis and estimation models were developed. The result of linear regression indicated that there is a strong correlation (R
