山西省绿色煤炭资源评价与分布特征研究

    Evaluation and distribution characteristics of green coal resources in Shanxi province

    • 摘要: 我国煤炭工业发展面临着“能源革命”的机遇与挑战,在此背景下,绿色煤炭资源理念应运而生。依据山西省煤炭资源禀赋特征及区域煤质特性,秉承“创新、协调、绿色、开放、共享”的发展理念,围绕山西省三大煤炭基地开发利用布局,构建了煤质及煤的工艺性能、煤层赋存条件、开采技术条件和生态条件四维一体的绿色煤炭资源评价体系,基于以往煤炭勘查成果,通过对评价因子叠合分析及相关技术条件评述,系统评价了山西省绿色煤炭资源的分布特征。结果表明:山西省绿色煤炭资源总体受限于煤层埋深、山西组灰分及太原组硫分,局部因煤层底板奥灰岩溶水威胁受限;山西省绿色煤炭资源保有量并不富裕,绿色煤炭保有资源量约791.1亿t,其中尚未被煤矿占用的资源量约590.5亿t,仅占保有煤炭资源总量的20%;绿色煤炭资源保有量中主要以炼焦用煤及化工用煤为主,绿色动力用煤资源量较少。

       

      Abstract: The development of coal industry of China is facing the opportunities and challenges of the “energy revolution”, the concept of green coal resources has emerged in the context.Based on coal resource and regional coal quality characteristics of Shanxi province, and adhering to the development concept of “innovation, coordination, green, openness, and sharing”, focusing on the development and utilization of the three major coal bases in Shanxi province, a four-dimensional green coal resource evaluation system has been constructed that integrates coal quality, coal process performance, coal seam storage conditions, mining technical conditions and ecological conditions.According to the results of previous coal exploration, the paper systematically evaluated the distribution characteristics of green coal resources of Shanxi province, through the overlay analysis of the evaluation factor mapping and the review of related technical conditions.It shows that Shanxi province green coal resources are generally limited by coal seam depth, ash content of Shanxi formation and sulfur content of Taiyuan formation, and partially restricted by the water of Ordovician limestones in coal seam floor.The amount of green coal resources in Shanxi province is not rich.The green coal resources are about 79.11 billion tons, of which about 59.05 billion tons are not occupied by coal mines, accounting for only 20% of the total coal resources.Green coal resources are mainly used for coking coal and chemical coal, while relatively less used for green power.
