Preface This article mainly discusses some issues in China’s coal resources, reserves, grading, exploration and development. I. Characteristics of China’s Coalfields China is one of the countries with the richest coal resources in the world and has been ahead of the rest of the world in the discovery, development and utilization of coal. Coalfields in our country have the following characteristics: the distribution of coalfields is strictly controlled by the tectonic system and has a specific distribution; the coal-accumulating process shows a wave-like evolution over time; the coal accumulation has obvious spatial relocation; , Coastal migration to the mainland; paleogeographic types of coal-accumulating changes are gradually diversified; China’s coal-bearing
