The effect of feed coal particle size on strength of briquette is discussed when different briquetting process and rank of coalification coal are adopted. The briquette strength is increased along with the feed coal particle size decreasing at the without binder and high-pressure briquetting process condition. The particle size of anthracite and bituminous may control on the high side at low pressure briquetting process and adding binder condition, however, the particle size should be controlled on the low side for the brown coal. The effect oh particle size distribution on the briquette strength is bigger.

Vigorous development briquette industrial is an important route for decreasing environmental pollution and effective utilization coal resource in Shanxi province. It is an effective route to obtain a new economic increasing point through coal deep processing and utilization local coal resource superiority. Also it is one of the effective measures for the coordinate development of economic and environment, and promoting sustainable development strategy implement. Therefore the briquette industrial has a wide development foreground. Some of the problems should be resolved before to develop the briquette industrial. The suggestion is provided for reference.

The market economy is favorable environment protection and its industrial development. Opportunity is suitable for development environment industrial in coal industry. It must integrate with the economic system reform, the market as a guide and adjustment of industrial and product structure as a juncture. The precedence development domain in coal environment industrial should be based on the demand of environment protection in coal industry.

The connotation of clean production ISO14001 standard, audit and examining and approving the environment management system are introduced. Also the similarities and differences of them are discussed. As an advanced technology measure and management method, clean production audit and environment management system should be achieved mastery through a comprehensive study and supplement each other of them. The object of decreasing pollution, decreasing consumption and save energy, sustainable development can be reached.

According to the water environment state that is published by Nation Department of Environmental protection in 1998 about 436 rivers were polluted in different extent among the 526 rivers in whole country. Fish and shrimp had been stamped out in 2,400 km long river due to pollution. Water quality of most rivers can't reach the standard. Therefore, polluted water treatment and river system repair technology should be put into serious study due to it is concerned about the sustainable development of nation economy. The relation technologies, development trend and problems are introduced in this paper.

The xingwen Mining Group Company is developed to a large scale coal enterprise due to rely on the technical reform and to excavate the potential in mine. Coal output may keep at more than 10 Mt/a. At present, the output of medium and high sulfur coal is higher, among which <1 % sulfur content coal is shared 25%on total output; 1%～2% sulfur content coal is shared 3% and the other is >2% sulfur content coal. The medium and high sulfur coal output will be increased year by year. Resent year, medium and high sulfur content coal cannot sale easy due to published the rigorous environment protection regulation. Therefore, research, development and application the clean coal technology is the only way for sustainable development in Xingwen Mining Group Company.

According to the analysis of occurrences of pyrite, clay mineral and organic sulfur in the main mined coal seam in Wuda coalfield, it can be seen that it is not practical to decrease the content of sulfur and ash in a single coal seam at present technical and economic condition. The best way to increase the coal quality is to lay the mining area reasonably, choose the ratio of the different coal seam appropriately, and realize the harmony of the geology, mining, and coal washing.
