“能源地质学”是地质工程专业的核心专业课程,也是地球物理专业的选修课程。本文针对课程中煤田地质学知识体系的指标多、过程多等特点,提出用数字来简化表征。使用了数字串联方法,详述了其中数字的含义,绘制了基本关系示意图。这种教学方式既能提高的学生学习兴趣,也能简化复杂关系,对课程的讲解起到很好的促进作用。 “Energy Geology ” is the core professional course of geo-engineering major, and also an elective course of geophysical specialty. In this paper, according to the characteristics of coal geological knowledge system in the course of coal and many other characteristics, it is proposed to simplify the characterization by using numbers. Using a digital concatenation method, which details the meaning of the figures, draw the basic relationship diagram. This kind of teaching method can not only improve students’ interest in learning, but also simplify the complicated relationship and play a good role in promoting the course.
