Coal combustion will emit a large amount of waste gas and dust, and seriously pollute the environment, so it is urgent to develop clean coal technology. Briquette technology is attracting more and more social attention, how to make briquettes have enough cold and hot strength is an important direction of the briquette technology research. Slime is by-product of coal washing and processing, with adhesive, calorific value, low calorific value and characteristics of a viscous material, increased gradually with the development of Chinas coal resources, raw coal into the washing rate also increase in the synchronization, and slime production also increased year by year. Therefore, fully rational use and recovery of coal, not only saving resources, environmental protection, but also has higher economic benefit. The use of Jiaozuo Fengying mine slime coal, Henan caking coal for coal based, through single factor experiment that slime and Henan caking coal ratio of 6:4, mechanical strength close to the standard requirements.
