发布时间：2018-07-15 22:25
【摘要】：伴生矿产资源是我国“十二五”期间将重点推进的综合开发和高效利用资源。我国煤系共伴生矿产资源丰富,储量大,品位高,对于煤炭企业来说,开采共伴生矿有着完善的生产设施和良好的自然条件,综合开发利用这些煤系共伴生矿产资源,不仅可以节省企业的投资,提高经济效益,增强企业竞争力,延长矿山的服务年限,发展循环经济,保障其可持续发展,还可以减少对矿环境的危害,保护环境。在五十多年的开采过程中,平庄西露天矿排放大量的煤矸石、辉绿岩及玄武岩,预计到毕坑为止累计排放煤矸石约3656万吨、辉绿岩约1719万吨、玄武岩约21360万吨。如何利用这些伴生矿产,变废为宝是目前该矿面临的一个主要问题之一。本文在收集相关资料的基础上,主要对西露天矿伴生矿产综合利用的各项指标进行测定。通过对其化验结果的分析,对西露天矿的煤矸石、辉绿岩及玄武岩的综合利用方向进行了综合评价：煤矸石发电、制砖及制备化工原料,辉绿岩和玄武岩生产铸石及岩棉。本文认为,西露天矿伴生矿产有着不错的发展前景,充分利用这些伴生矿产,可以取得很好的经济效益、社会效益和环境效益。
[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.
