【摘要】：煤是我國(guó)重要能源之一,淮南煤田為我國(guó)東部最重要的能源基地,在采煤過程中大量的煤矸石排放堆積不僅對(duì)生態(tài)環(huán)境造成了嚴(yán)重危害,同時(shí)也是對(duì)資源的浪費(fèi),因此,研究煤矸石的資源化再利用具有重要的現(xiàn)實(shí)意義。 由于淮南礦區(qū)不同煤礦、不同煤層煤矸石理化性質(zhì)的不同,其有效的資源化再利用模式尚未形成。為系統(tǒng)研究淮南礦區(qū)主采煤層煤矸石的理化性質(zhì)與元素分布特征,提出科學(xué)的矸石再利用模式,本文利用多種精密儀器和數(shù)理統(tǒng)計(jì)方法對(duì)淮南礦區(qū)丁集、謝橋和新莊孜煤礦11、13煤層的煤矸石樣品進(jìn)行了系統(tǒng)采集與測(cè)試,分析了其化學(xué)成分特征以及微量元素的分布特征。結(jié)果表明淮南不同煤礦、不同煤層煤矸石的化學(xué)組成分別有各自的特征。結(jié)合多種資源化利用途徑對(duì)原材料性能的要求,研究分析了淮南礦區(qū)不同煤礦煤矸石的利用方案,提出了多種煤矸石資源化再利用的途徑,為淮南礦區(qū)固體廢物無害化綜合治理提供了理論參考和技術(shù)支持。
[Abstract]:Coal is one of the most important energy sources in China. Huainan coalfield is the most important energy base in the east of China. During the coal mining process, a large amount of coal gangue emissions and accumulations not only cause serious harm to the ecological environment, but also waste the resources. It is of great practical significance to study the reuse of coal gangue. Due to the different physical and chemical properties of coal gangue in different coal mines in Huainan mining area, its effective resource reuse model has not yet been formed. In order to systematically study the physicochemical properties and elemental distribution characteristics of coal gangue in main coal seam of Huainan mining area, a scientific reuse mode of gangue is put forward. In this paper, a variety of precise instruments and mathematical statistics methods are used to study Dingji in Huainan mining area. The coal gangue samples of coal seam 11yang13 in Xieqiao and Xinzhuangzi coal mines were collected and tested systematically, and the chemical composition characteristics and the distribution characteristics of trace elements were analyzed. The results show that the chemical composition of coal gangue in different coal mines and different coal seams in Huainan has its own characteristics. According to the requirements of various ways of resource utilization to the performance of raw materials, the utilization schemes of coal gangue in different coal mines in Huainan mining area are studied and analyzed, and the ways of reuse of coal gangue are put forward. It provides theoretical reference and technical support for comprehensive treatment of solid waste in Huainan mining area.
