Modeling of Three Flat Coal Seams Strata Developing at Open Pit Miming
GVOZDKOVA, Tatiana; MARKOV, Sergey; Demirel, Nuray; ANYONA, Serony (EDP Sciences; 2017-11-22)
The use of low-cost direct dumpling technology, as is well known, has a relatively limited field of application: flat coal seams, and the higher the dip angle of the seam, the more difficult it is to place the necessary volume of overburden rock in the dumping layers. For this, we have to pour four-tier dumps. In this article, four possible options for piling the dump have been studied and prerequisites have been made for further research aimed at improving the efficiency of the use of direct dumpling techn...
A probabilistic design approach for rock slopes
DUZGUN, HSB; Karpuz, Celal; Yücemen, Mehmet Semih (1998-10-09)
The basic aim of this study is to develop a reliability-based methodology for the practical design of rock slopes. The advanced first-order second-moment (AFOSM) approach is adapted as;the reliability assessment model. In the reliability-based design methodology, the first step is the modeling and quantification of uncertainties associated with the design parameters. Since the safety of a rock slope is most sensitive to the shear strength of discontinuities, the uncertainty analysis is focused on the parame...

3-dimensional measurements of morphological properties of particles
Hicyilmaz, C; Bilgen, S (1996-09-26)
Morphological properties of particles are important in mineral processing. Flotation recoveries are affected by surface roughness and acuteness of particles. A novel technique was developed to measure the morphological properties of particles 3- dimensionally. Pyrite sample ground in autogeneous and ball mill to differentiate the surface properties was used in this study.

24-26 April, 2017 the Scientific Practical Conference "International Innovative Mining Symposium (in memory of Prof. Vladimir Pronoza)" was successfully organized at T.F. Gorbachev Kuzbass State Technical University - KuzSTU (Kemerovo Russia). More than 20 participants submitted their papers in presence, and more than 40 authors sent their papers for virtual participation. The main participants of the conference - Keynote Speakers - paid special attention to the development of international cooperation of t...
