【摘要】：伴生礦產資源是我國“十二五”期間將重點推進的綜合開發(fā)和高效利用資源。我國煤系共伴生礦產資源豐富,儲量大,品位高,對于煤炭企業(yè)來說,開采共伴生礦有著完善的生產設施和良好的自然條件,綜合開發(fā)利用這些煤系共伴生礦產資源,不僅可以節(jié)省企業(yè)的投資,提高經濟效益,增強企業(yè)競爭力,延長礦山的服務年限,發(fā)展循環(huán)經濟,保障其可持續(xù)發(fā)展,還可以減少對礦環(huán)境的危害,保護環(huán)境。在五十多年的開采過程中,平莊西露天礦排放大量的煤矸石、輝綠巖及玄武巖,預計到畢坑為止累計排放煤矸石約3656萬噸、輝綠巖約1719萬噸、玄武巖約21360萬噸。如何利用這些伴生礦產,變廢為寶是目前該礦面臨的一個主要問題之一。本文在收集相關資料的基礎上,主要對西露天礦伴生礦產綜合利用的各項指標進行測定。通過對其化驗結果的分析,對西露天礦的煤矸石、輝綠巖及玄武巖的綜合利用方向進行了綜合評價：煤矸石發(fā)電、制磚及制備化工原料,輝綠巖和玄武巖生產鑄石及巖棉。本文認為,西露天礦伴生礦產有著不錯的發(fā)展前景,充分利用這些伴生礦產,可以取得很好的經濟效益、社會效益和環(huán)境效益。
[Abstract]:Accompanying mineral resources are the comprehensive development and efficient utilization of resources during the 12th Five-Year Plan period in China. China's coal measures are rich in associated mineral resources with large reserves and high grade. For coal enterprises, there are perfect production facilities and good natural conditions for the exploitation of co-associated minerals, and comprehensive development and utilization of these coals' associated mineral resources. It can not only save the investment of enterprises, improve economic benefits, enhance the competitiveness of enterprises, prolong the service life of mines, develop circular economy, guarantee its sustainable development, but also reduce the harm to the mine environment and protect the environment. In the mining process of more than 50 years, a large amount of coal gangue, diabase and basalt are discharged from Pingzhuang west opencast mine. It is estimated that up to the end of Bikeng, the total discharge of coal gangue is about 36.56 million tons, diabase is about 17.19 million tons, and basalt is about 213.6 million tons. How to make use of these associated minerals and turn waste into treasure is one of the main problems faced by the mine at present. On the basis of collecting relevant data, this paper mainly measures the comprehensive utilization indexes of the associated minerals in west opencast mine. The comprehensive utilization direction of coal gangue, diabase and basalt in the west opencast mine is evaluated by analyzing the results of the test: coal gangue power generation, brick making and chemical raw materials, and diabase and basalt producing castings and rock wool. This paper holds that the associated mineral resources in the West Open-pit Mine have a good prospect of development, and the full utilization of these associated minerals can achieve good economic, social and environmental benefits.
