In response to climate change, protect the environment and reduce air pollution, the coal consumption total amount control has been on the agenda by every countries and regions. Shandong is the largest coal consumption province in our country, with the swift growth of coal consumption, so the situation of the total coal consumption control is very serious. This subject makes the breakthrough direction of future coal control clear by analyzing the existing coal-control pressure of the Shandong Province. This subject start from coal production to the whole process of production and life, Regulates at different stages. This subject discusses coal-control system,puts forward the corresponding Safeguard mechanism and provides policy Suggestions for relevant decision-making departments, in order to better ensure the smooth realization of the Shandong province coal-control mission.
