The mines operate using a continuous mining system comprised of multiple bucket wheel excavators, belt conveyors, spreaders and stackers. There is a control centre for each mine, comprising of aspect servers, OPC servers and a SCADA system which interfaces with PLCs at each equipment unit in the field. The overall data management infrastructure is installed on the main network system and draws data from the OPC servers at each mine. In order to collect the data, the application is developed using event driven functionality as well as data polls. Data can then be modified by the control tower personnel. The application generates reports on a daily basis for production monitoring, productivity, equipment performance and utilisation as well as various maintenance tasks. The system has been in operation at the surface lignite mines in northern Greece since 2011 and has been embraced by mine personnel for decision making and planning.","PeriodicalId":38622,"journal":{"name":"International Journal of Mining and Mineral Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66731330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research includes a development of alkali-activated materials (AAMs) from low-alumina MTs. A series of samples with varying compositional ratios was synthesised from a combination of different activators, MT powder and water. Curing temperature of 40°C led to the strengthening of the AAMs. The effects of alkali activator addition on the phase evolution and morphology of the reaction products were investigated by using the XRD and SEM/EDS techniques. The results demonstrate that an increase in the percentage of the activator solution led to an increase in compressive strength and change the morphology structure of the reaction products. It should be noted that the alkali activation of MTs creates a new material with potential environmental protection applications, such as low permeable covers and a sustainable material with using geopolymerisation technology.","PeriodicalId":38622,"journal":{"name":"International Journal of Mining and Mineral Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/ijmme.2019.104450","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66730971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the loading mechanism in this haulage system still possesses a great challenge to its overall optimal efficiency. It has been demonstrated that high loading time is the main pitfall to high advance rates in monorail application. In this paper, the analytic hierarchy process and Yager's multiple criteria decision making techniques were used to select the optimal loading mechanism in the electric monorail transport system among three loading alternatives, namely, electric loader, conventional load-haul-dump unit and pneumatic loading system. Results of the two methods show that the electric loading technique is the optimal monorail loading system for efficient decline development in narrow vein deposits. Additionally, sensitivity analyses under the two techniques show that the electric loader system is always selected as the optimal solution to ±40% changes in the weight of criteria. It was also deduced that the solution under both methods is most sensitive to changes in the weight of the loading rate criterion.","PeriodicalId":38622,"journal":{"name":"International Journal of Mining and Mineral Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/ijmme.2019.104457","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66731084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ampere consumption and rock properties such as uniaxial compressive strength, Young modulus, Mohs hardness and Schimazek's F-abrasiveness factor were evaluated using linear and nonlinear regression analysis. The result of linear regression indicated that there is a strong correlation (R2 = 0.85) between ampere consumption and uniaxial compressive strength compared to other parameters. The developed nonlinear models were verified by statistical tests and the best predicted model was selected. It was concluded that the ampere consumption of carbonate rocks using gang saws can reliably be estimated with a coefficient of correlation above 0.9 using the developed model. It is very useful to evaluate the energy consumption and predict the energy cost for a new rock type by only the mechanical properties testing.","PeriodicalId":38622,"journal":{"name":"International Journal of Mining and Mineral Engineering","volume":"9 1","pages":"216"},"PeriodicalIF":0.0,"publicationDate":"2018-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42890556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper selected the Bulianta coal mine in Inner Mongolia as a research area. Based on GIS/RS technology, the change in the spatial patterns of soil erosion in the study area were quantitatively evaluated using the rule of mining subsidence and the Universal Soil Loss Equation (USLE). The results show that underground coal mining has a significant effect on terrain by changing the slope length and slope steepness (LS), vegetation growth was also affected by a trend of overall reduction. In general, soil erosion in the Bulianta mining area generally showed an increasing trend from pre-mining topography to surface subsidence after mining, both from the perspective of soil erosion area and the perspective of soil erosion quantity.","PeriodicalId":38622,"journal":{"name":"International Journal of Mining and Mineral Engineering","volume":"9 1","pages":"240"},"PeriodicalIF":0.0,"publicationDate":"2018-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42216471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper explores how abandoned mine voids can be utilised 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.","PeriodicalId":38622,"journal":{"name":"International Journal of Mining and Mineral Engineering","volume":"9 1","pages":"177"},"PeriodicalIF":0.0,"publicationDate":"2018-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49281383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concerned performances include head, efficiency and so on. A compressor's original head or efficiency characteristic curve may deviate from its actual one because of various reasons after it runs in field for a period of time. So correction is needed before these characteristic curves are used for simulation, optimisation or other applications. A compressor's actual head and efficiency are extracted from its operating records and used for correction. The correction method is designed according to the idea to move a compressor's characteristic curves to best fit its actual performance. Two different types of compressors operated on Central Asia – China gas pipeline are utilised to test the proposed method and satisfactory results are got.","PeriodicalId":38622,"journal":{"name":"International Journal of Mining and Mineral Engineering","volume":"9 1","pages":"122"},"PeriodicalIF":0.0,"publicationDate":"2018-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44025496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
