Soleymani Shishvan, M. (author), Benndorf, J. (author)This paper examines a problem related to dispatching materials to spreaders in coal (lignite) mines operated under the paradigm of continuously excavated material flow. In the considered particular case, complexity arises from different material types of overburden to be placed on the dump site in pre-defined patterns that guarantee...journal article 2019

Wambeke, T. (author), Benndorf, J. (author)The mining industry continuously struggles to keep produced tonnages and grades aligned with targets derived from model-based expectations. Deviations often result from the inability to characterise short-term production units accurately based on sparsely distributed exploration data. During operation, the characterisation of short-term...journal article 2018

Yuksel-Pelk, C. (author), Minnecker, Corinna (author), Soleymani Shishvan, M. (author), Benndorf, J. (author), Buxton, M.W.N. (author)A primary concern of the mining industry is to meet production targets, which are required and defined by customers. Deviations from these targets, in terms of quality and quantity, highly affect the economical aspect. Recently, an efficient resource model updating framework concept has been proposed aiming for the improvement of raw material...journal article 2018

Wambeke, T. (author), Elder, D. (author), Miller, A. (author), Benndorf, J. (author), Peattie, R. (author)The ball mill is usually the largest energy consumer at a mine site and significantly affects operational expenditures. Given a target particle size, Bond Mill Work Index estimates are used to predict a ball mill’s throughput. In order to maximize ball mill throughput and optimize energy utilization, it is important to get these estimates right....journal article 2018

Soleymani Shishvan, M. (author), Benndorf, J. (author)Material management in opencast mines is concerned with planning, organizing, and control of the flow of materials from their extraction points to destinations. It can be strongly affected by operational decisions that have to be made during the production process. To date, little research has focused on the application of simulation modeling...journal article 2017

Yüksel, Cansın (author), Benndorf, J. (author), Lindig, Matthias (author), Lohsträter, Oliver (author)An efficient resource model updating framework concept was proposed aiming for the improvement of raw material quality control and process efficiency in any type of mining operation. The concept integrates sensor data measured online on the production line into the resource or grade/quality control model and continuously provides locally more...journal article 2017

Benndorf, J. (author), Jansen, J.D. (author)Advanced data acquisition and process modelling technology provide ‘real-time’ data and decision support capacity for different aspects of the resource extraction process. Closed-loop approaches have recently been applied to utilize information extracted from these data in combination with advanced computing technology for improved production...journal article 2017

Wambeke, T. (author), Benndorf, J. (author)One of the main challenges of the mining industry is to ensure that produced tonnages and grades are aligned with targets derived from model-based expectations. Unexpected deviations, resulting from large uncertainties in the grade control model, often occur and strongly impact resource recovery and process efficiency. During operation, local...journal article 2017

Wambeke, T. (author), Benndorf, J. (author)Characterization of spatial variability in earth science commonly requires random fields which are stationary within delineated domains. This contribution presents an alternative approach for simulating attributes in combination with a non-stationary first-order moment. A new procedure is presented to unambiguously decompose the observed...journal article 2016

Yuksel-Pelk, C. (author), Thielemann, T (author), Wambeke, T. (author), Benndorf, J. (author)In recent years a real-time resource model updating concept has proven to increase the material quality control and process efficiency in geostatistics. The real-time resource model updating concept integrates online-sensor data, measured fromthe production line, into the resourcemodel. This integration quickly improves the accuracy of the...journal article 2016

Soleymani Shishvan, M. (author), Benndorf, J. (author)Continuous mining systems containing multiple excavators producing multiple products of raw materials are highly complex, exhibiting strong interdependency between constituents. Furthermore, random variables govern the system, which causes uncertainty in the supply of raw materials: uncertainty in knowledge about the reserve, the quantity...journal article 2016

Benndorf, J. (author)The resource model is the foundation for mineral project evaluation, mine planning and operations production control. The representativeness of such a model depends on both, the quality of data available and the modelling technique applied. This contribution reviews recent developments in geostatistical resource modelling first focusing on...conference paper 2015

Naworyta, W. (author), Sypniowski, S. (author), Benndorf, J. (author)The aim of coal quality control in coal mines is to supply power plants daily with extracted raw material within certain coal quality constraints. On the example of a selected part of a lignite deposit, the problem of quality control for the runof-mine lignite stream is discussed. The main goal is to understand potential fluctuations and...journal article 2015
