Major coal varieties as well as gangue in the huainan were studied in this and both ADXRD and EDXRD patterns of the samples were collected. Differences in the physical phase informa tion the EDXRD patterns of and gangue are analyzed to extract the identification features of and gangue to achieve the identification of and gangue by the PSO-SVM model. Then, the technique characterizing metamorphism ing technology mainly focus on the identification of coal and gangue, and no in-depth research has been carried out on the identification of coal species. Accordingly, in order to preliminary screen coal types, this paper proposed a method to predict the coal metamorphic degree while identifying coal and gangue based on Energy Dispersive X-Ray Diffraction (EDXRD) principle with 1/3 cok ing coal, gas coal, and gangue from Huainan mine, China as the research object. Differences in the phase composition of 1/3 coking coal, gas coal, and gangue were analyzed by combining the EDXRD patterns with the Angle Dispersive X-Ray Diffraction (ADXRD) patterns. The calculation method for characterizing the metamorphism degree of coal by EDXRD patterns was investigated, and then a PSO-SVM model for the classification of coal and gangue and the prediction of coal metamorphism degree was developed. Based on the results, it is shown that by embedding the calculation method of coal metamorphism degree into the coal and gangue identification model, the PSO-SVM model can identify coal and gangue and also output the metamorphism degree of coal, which in turn achieves the purpose of preliminary screening of coal types. As such, the method provides a new way of thinking and theoretical reference for coal and gangue identification.","PeriodicalId":50416,"journal":{"name":"Gospodarka Surowcami Mineralnymi-Mineral Resources Management","volume":"40 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78032241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Havryshok","doi":"10.24425/gsm.2019.128543","DOIUrl":"https://doi.org/10.24425/gsm.2019.128543","url":null,"abstract":"The article analyzes the present state of the phosphate raw material base to meet Ukrainian chemical enterprises’ needs. In Ukraine, a number of complex apatite and phosphorite deposits have been explored. Their exploitation can lead to a complete supply of Ukrainian chemical enterprises with raw materials and can partly reduce the amount of expensive imported phosphate mineral fertilizers. At present, the following deposits, where apatite is connected with other useful components, are prepared for exploitation: stremyhorod, Fedorivka, Novopoltavka, kropyvna and others. The advantage of the development of these deposits is the possibility to extract apatite along with the production of rare earth concentrates, ilmenite, titanomagnetite, as well as feldspars, olivine, pyroxenes, mica and others which will significantly increase the profitability of the deposits development. The alternative to apatite-containing deposits in Ukraine can be sedimentary deposits of nodule, granular and mixed type phosphorites. Phosphorite deposits can be used mainly for the production of phosphorite and limestone flour. Considerable resources of granular phosphorites have been discovered in Volyn-Podillia and Dnieper-Donetsk which are considered to have a various agricultural effect. They are environmentally friendly ores without impurity which prevents plants from cesium, strontium and reduces nitrates in the soil. Arranging the exploration of phosphorite ores in certain parts of Volyn-Podillia basin and Dnieper-Donets Rift is recommended. 25 Syvyi et all 2019 / Gospodarka Surowcami Mineralnymi – Mineral Resources Management 35(4), 5–26 FosForany ukrainy jako surowce do produkcji nawozów mineralnych i środków polepszających S ł o w a k l u c z o w e rudy apatytowe, rudy fosforytowe, zasoby, złoża, surowce s t r e s z c z e n i e W artykule przeanalizowano obecny stan bazy surowcowej fosforanów celu zaspokojenia potrzeb ukraińskich przedsiębiorstw chemicznych. Na terenie Ukrainy odkryto kilkanaście złóż apatytu i fosforytu. Ich eksploatacja może doprowadzić do pełnego zaopatrzenia ukraińskich przedsiębiorstw chemicznych w te surowce i może częściowo zmniejszyć ilość importowanych drogich nawozów fosforowych. Obecnie do eksploatacji przygotowywane są następujące złoża, w których apatyt jest związany z innymi pożytecznymi składnikami: Stremyhorod, Fedorivka, Novopoltavka, Kropyvna i inne. Zaletą zagospodarowania tych złóż jest możliwość wydobywania apatytu wraz z produkcją koncentratów ziem rzadkich, ilmenitu, tytanomagnetytu, a także skaleni, oliwinu, piroksenów, miki i innych, co znacznie zwiększy opłacalność rozwoju złóż. Alternatywą dla złóż zawierających apatyt na Ukrainie mogą być złoża osadowe fosforytów grudkowych, granulowanych i mieszanych. Złoża fosforytów można wykorzystać głównie do produkcji fosforytu i mąki wapiennej. Ponadto na Wołyniu Podolskim i Dnieprze-Doniecku odkryto znaczne rezerwy fosforytów ziarnistych, które mają różne zastosowanie rolnicze.
