Based on fuzzy mathematics, comprehensive comparisons among four kinds of materials for manufacturing shearer bits were made in six aspects which are respectively hardness, tensile strength, impact toughness, relative wearability, relative lifespan and relative cost. Material 4 is preferred to be the targeted choice for manufacturing bits with superior comprehensive and economic performances.
