Research-derived Achievements in the Coal Preparation Field during The Ninth Five-Year Plan Period and Their Influence on china's coal Preparation Technology

The paper presents a review of the background and guiding ideology for selecting coal preparation related study programs and setting their objectives during the Ninth five-Year Plan period. Following this, an introduction is made to the statedesignated and ministerial-level key group programs together with the sub-programs in each group involving 5 technology spheres for tackling in that period. The emphasis is placed on introduction to the technologies investigated, their characteristics and scope of applications. These involve desulphurization of highash difficult-to-wash coals; simplified large-size high-efficiency total H.M separation process; dry and water-saving coal cleaning benefaction of fine coal; and technologies applicable for upgrading of traditional coal cleaning processes. An analysis is also made of the influence of these research-derived accomplishments on China's coal preparation technology and their role for propelling forward the country's coal preparation industry.
