The coal is the main energy and important raw material, as well as leads to development of national economy and society. The coal industries are important industries which relate to national eeonomy liteline and national safety. Higher requests are proposed for the coal industry development due to the rapid growth economy in China, With the guidance of Deng Xiaoping theory and important thought of "three representatives" and scientific outlook on development, coal industries carry out the thoughts of safety development,clean development and harmonious development that insure their development sustainable,steady and healthy. The coal output touches a new peak in 2008, reaches 2. 72 billion tons which the percentage increases 7.5%. Furthermore, the number of coal mine disasters and death toll come down 19.3% and 15.1% respectively. The mortality reduces to 1. 182 in millions coal mine and decreases 20.4%, which create the best achievement in the history.
