石头梅露天矿资源特征及绿色开发构想

Resource characteristics and green development idea of Shitoumei Open-pit Coal Mine

石头梅矿区是三塘湖煤田的重要组成部分,储量巨大、成煤条件良好。从矿区地质条件看,中新生代以来构造运动相对平静,地层基本以水平状展布,倾斜角度变化不大,水文地质条件简单。矿区煤炭资源以储层浅、层数多,厚度大,含水少、灰分低、挥发分高、热值高,硫、磷、氟、砷等有害元素含量低为特征。主要煤种为优质不粘煤和长焰煤,局部层位煤岩含油量偏高,近地浅表层煤腐植酸含量高。基于其资源特征和区域地质、地理、气候条件,经过深入的野外勘察、现场调研和资料分析,针对矿区严重缺水,而风能、太阳能异常丰富的特点,提出实施“节水低碳绿色多元长链”的绿色矿山建设方案,为石头梅露天矿的可持续发展奠定基础。

Shitoumei mining area,an important part of Santanghu coalfield,has huge coal reserves and good coal forming conditions.From the geological conditions,the tectonic movement is relatively calm from the Mesozoic and Cenozoic,the strata are basically distributed horizontally and the inclination angle changes little,and the hydrogeological conditions are simple.Coal resources in the mining area are characterized by shallow reservoir,many layers,large thickness,less water content,low ash content,high volatile matter,high calorific value,and low content of sulfur,phosphorus,fluorine,arsenic and other harmful elements.The main coal types are high-quality non caking coal and long flame coal.The oil content of coal rock in some layers is high,and the humic acid content of coal near the surface is high.Based on its resource characteristics and regional geological,geographical and climatic conditions,through in-depth field investigation,on-site surrey and data analysis,in view of the serious water shortage in the mining area and the extremely rich wind and solar energy,the green mine construction scheme of"water-saving,low-carbon,green,diversified and long chain"was put forward,so as to lay a foundation for the sustainable development of Shitoumei open-pit mine.
