在当前建设建设资源节约型和环境友好型社会的大背景下,煤矿绿色开采技术在处理资源开采与环境保护协调发展问题方面发挥着越来越重要的作用。本文首先指出了煤炭绿色开采的内涵及其技术体系,然后重点从四个方面论述了煤炭绿色开采技术的主要内容,最后简要介绍了基于关键层理论的绿色开采技术研究与实践问题。 Under the current background of building a resource-saving and environment-friendly society, coal mining green mining technology plays an increasingly important role in handling the coordinated development of resource exploitation and environmental protection. This paper first points out the connotation and technical system of green coal mining, and then discusses the main contents of green coal mining technology from four aspects. Finally, it briefly introduces the research and practice of green mining technology based on the key layer theory.
