Special Issue Information

Dear Colleagues,

Mathematical geosciences include geostatistics, simulation, uncertainty quantification, classification, numerical and statistical analysis, data/big data analysis, machine learning, and deep learning. All these methods in 2D (on the ground) to even 5D (underground/subsurface) have been developing and being applied to geological data in different fields such as exploration geochemistry, exploration geophysics, remote sensing, petroleum engineering, mining engineering, hydrology, GIS and mineral prospectivity mapping, etc. In exploration geochemistry, such methods have been taken into consideration to recognize geochemical anomalies vectoring into mineral deposits with less uncertainty. This helps decision-makers to focus follow-up exploration projects on the anomalies defined as significant using robust models. Considering these points, all papers related to advanced methods and developments in applied geochemistry using various anomaly classification methods such as fractal/multifractals and geostatistical modeling (e.g., uni/multivariate analysis and simulation methods), error propagation and uncertainty quantification, GIS and mineral prospectivity mapping, and numerical/data analysis are welcome.

Manuscript Submission Information

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 submissions that pass pre-check are 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. Mining is an international peer-reviewed open access quarterly 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 1000 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.

This paper proposes a stochastic frontier model for measuring both technical and environmental performance at the mine level by using a translog production function. The Kardia Field opencast lignite mine of the Greek Public Power Corporation (PPC), S.A. is the topic of the case study. Efficiency ratings are derived over a long period of time using annual operating data, and in addition, the determinants of inefficiency are established by means of the technical inefficiency effects model. In the light of the results, there is a strong correlation between technical and environmental efficiency; the results are validated by those produced by data envelopment analysis (DEA). In addition, the stripping ratio is identified as the statistically significant determinant of performance. The proposed framework could be used as an instrument to measure the efficiency of lignite mining operations and to identify the drivers of performance. Full article
