Abstract The exploration and development of fossil energy has made a significant contribution to my country's rapid industrialization and economic take-off. At the same time, it is also facing the increasing rate of external dependence and the impact on the ecological environment. For this reason, different types of new energy are widely proposed and tested. Throughout my country's energy development and research status, it shows that (1) my country is low in oil, gas, and coal-rich, and the latter is the source of clean fossil energy development in the future. (2) CBM has great potential in natural gas energy development and supply. (3) The diversified conversion of coal energy is the trajectory of efficient coal utilization. This only shows that in this century, the diversified transformation of coalbed methane and coal must be the main force in my country's energy matching and development supply.
