“…Earlier studies provided information on postulated operational states of biological fibrous materials grinding, including bio-media energy: quality, efficiency, nondestructiveness. the process quality is affected by the design-construction stage and the manner of its management as well as the operators, customer service staff and the customer, recipient of the final product -power plants or individual clients in the case of energy materials grinding (Flizikowski et al, 2015b;Flizikowski et al, 2017;Fuerstenau and Abouzeid, 2002;Jeswiet and Szekeres, 2016). Production of an adequate quality product, while keeping efficiency and nondestructiveness, requires development of a thorough and consistent design procedure and constant control of the process and product parameters for structural changes to be introduced while designing (Dabbour et al, 2015;Pan et al, 2007).…”

Grinding operations are one of the most commonly used preparation processes in many branches, for example in food, energy and chemical sectors. This paper focuses on the issues connected with design of technical objects in accordance with sustainable development assumptions. The aim of this study is to create methodology of sustainable design of grinding machine, including external influences involved in their operation, to increase safety, energy, economic and eco- efficiency. The problem formulated as a question: what techniques, equipment, methods, and ways should be used in design to obtain a new, better grinder structure? To resolve the problem, original methodology of sustainable design has been created.

“…The mining industry is an essential industrial branch with a high energy demand; for example, copper mining is expected to consume 41.1 terawatt-hours (TWh) of energy in the near future [9]. Furthermore, mining operations have environmental consequences such as causing soil pollution, generating greenhouse gas (GHG) emissions, and polluting clean water systems; these problems require the mining sector to implement development strategies that are integrated with sustainability concerns [10,11].…”

The present study analyzed the potential of eight operational mining sites in Uzbekistan for the installation of photovoltaic (PV) systems: Sarmich, Ingichka, Kuytosh, Yakhton, Chauli, Sherobod, Chorkesar, and Tebinbuloq. A PV system with 1 MW capacity, which required a total of 4926 m2 of project land, was considered. The renewable energy analysis software RETScreen, developed by Natural Resources Canada (NRC), was used to calculate energy production, greenhouse gas reduction, and financial factors of the PV systems in the selected study areas. The iron mine Tebinbuloq in Karakalpak showed the highest potential, with annual electricity production of approximately 1685 MWh, equating to a potential reduction of approximately 930 tons of greenhouse gases. The economic benefit of the PV system in this mine was $2.217 million USD net present value with a project payback period of approximately 13 years. The results of precision checks of satellite- and ground-based solar measurements showed high correlations; hence, satellite-based data can be applied for solar project assessments where solar monitoring meteorological stations are not available.

“…However, it is showed that, nowadays, most ventilation systems generally supply excess fresh air to remove methane gas and ensure a safe working environment as required by local codes, and the specific energy consumption value differs from different site conditions. For example, Jeswiet stated that at least 25% of electric energy consumption in mining is costed by ventilation purposes, Mielli and Bongiovanni indicated that approximately 15%-40% of the operating costs can be attributed to mine ventilation systems, and up to 60% of the total mining operation costs are connected with mine ventilation as revealed by Reddy [8][9][10][11]. With the increase of energy and operation costs and implementation of a carbon tax, a cost-effective ventilation and methane control strategy is strongly required for the mining industry, which means that the ventilation system should be designed to meet the regulatory limits and ensure a safe and productive working environment whilst keeping energy usage and operating costs to a minimum.…”

A Case Study of an Optimized Intermittent Ventilation Strategy Based on CFD Modeling and the Concept of FCT

With the increasing operation costs and implementation of carbon tax in the underground coal mining systems, a cost-effective ventilation system with well methane removal efficiency becomes highly required. Since the intermittent ventilation provides a novel approach in energy saving, there still exists some scientific issues. This paper adopts the design concept of frequency conversion technology (FCT) to the ventilation pattern design for the first time, and an optimized intermittent ventilation strategy is proposed. Specifically, a real excavation laneway of a coal mine in China is established as the physical model, and computational fluid dynamic (CFD) approaches are utilized to investigate the spatiotemporal characteristics of airflow behavior and methane distribution. Plus, the period of intermittency and appropriate air velocity are scientifically defined based on the conception of FCT by conducting the parametric studies. Therefore, an optimized case is brought out with well methane removal efficiency and remarkable energy reduction of 39.2% in a ventilation period. Furthermore, the simulation result is verified to be reliable by comparing with field measurements. The result demonstrates that a balance of significant energy saving and the methane removal requirement based on the concept of FTC is possible, which could in turn provide good operational support for FTC.
