Abstract: Through the unremitting efforts of the workers engaging in the formulation of standards for China′s coal preparation sector over the past half a century, the basic standardization system of coal preparation technologies is currently available. The 96 coal preparation-related standard documents successively compiled can basically meet the requirements of present coal preparation related scientific research, design and production work, which contributes significantly to the development of China′s coal preparation technologies. The paper introduces the state-of-the-art of the standardization work and points out the problems and deficiencies in this respect. Finally, the key work that need to be dealt with over a period in the future is proposed.
