【Abstract】 According to the multiphase fuzzy statistical method, and with purpose of practical application, three phase fuzzy membership function for low ash coal, high ash coal and gangue respectively in ash domain have been developed, and a practical model adjusting algorithm is proposed. Experimental results show that the sorting index can reach to as high as 90% with the method proposed, which well meets the practical requirements.更多还原
