It is found the entry of foreign matters and infiltration of water into raw coal during mining process and the contents of media solids and moisture of clean coal are the main influential factors.Results of analysis show that coal quality control work during mining process and that in coal cleaning process can supplement and complement each other. To do a good work in both aspects can help ensure safe operation, enhance coal quality management level and produce more social benefits.
