Annaba suffers from air pollution due to the industrial activities occurring in the province including, electricity generation, waste incineration, chemistry and other small additional industrial operations. However, mining, steel industry and metallurgy are considered among the most polluting activities. The aim of our research is to assess the risks of air pollution emissions with NO2, SO2, Toluene and Benzene as a result of industrial enterprises activities in Annaba province. The application of geographical information system (GIS) mapping based on automatic monitoring networks of air quality, allows us the assessment of air pollution risks in the studied area. Two zones of air pollution with N02 in the level of 1 MPC has been recorded near the blast furnaces and the steel shop, the second halo of NO2 pollution was fixed over residential infrastructures. Moreover, revealed a tendency to higher content of nitrogen dioxide in the atmosphere of the bigger part of Annaba region. Corresponding to the data obtained from stationary monitoring networks, the annual average concentration of SO2 was significantly lower than the MPC. Based on GIS maps there are two areas with SO2 pollution inside the territory of El Hadjar metallurgical plant. A significant increase in concentrations of NO2 in the atmosphere of the industrial areas was recorded in the first decade. On average during three years the highest content of technogenic dust was detected in El Bouni.","PeriodicalId":43629,"journal":{"name":"Mining Science","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85677640","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}

The main emission sources are ferrous metallurgical plants and the coal industry. The purpose of this project is to estimate the degree of pollution from dioxides of nitrogen and sulfur in the south-eastern part of Ukraine using satellite data. An assessment of atmospheric pollution by NO2 is carried out using the data from satellite spectrometer EOS/OMI, and information products Level 3 from Goddard Earth Sciences Data, (GES DISC) NASA for 2009-2014. According to the results study, the largest area of propagation of SO2 aerosol was observed in the industrial agglomerations of Kryvyi Rih, Dnipropetrovs’k and Vilnohirs’k.However, a somewhat smaller content of NO2 in the air recorded near the town of Kryvyi Rih and the cities of Vilnohirs’k and Zaporizhia.The results obtained from this research will aid the creation of awareness among Ukraine’s policy makers about the need for air pollution abatement, and also serve as a stepping stone towards addressing the negative impacts of acid rains.","PeriodicalId":43629,"journal":{"name":"Mining Science","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80100781","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}

In addition to monitoring of belts during their operation on conveyors this device can be used in LTT as the new tool in belts resistance to puncture investigations. High resolution images of changes in magnetic field of magnetized cord wires can be used for evaluation of failures and cuts caused by dynamic impact of iron head (striker) during laboratory tests without belt cover removal. The usefulness of the device is even greater due to not only condition of steel cord belts can be evaluated, what for this device was developed, but it allows also on observations of failures in impact-resistant metal breakers in textile belts. Breakers are frequently made of thin wires vulcanized above carcass inside the top cover laterally to the center line of the belt. The aim of breakers is protection of the expensive core against failures caused by big lumps of rock with sharp edges falling onto belt surface in loading points. Their role is shock absorption to minimize gouging and resistance of longitudinal rips. Due to breaker wires can also be magnetized after changing the direction of samples of punctured belts they can be monitored using the developed device at the testing conveyor. In the paper the first outcomes of application of magnetic diagnostic device for evaluation of punctured steel cord belts and textile belts with metal breakers are presented.","PeriodicalId":43629,"journal":{"name":"Mining Science","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84981618","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}
