Based on many years of practical experience in the school of mechanics and civil engineering of china university of mining and technology, this paper puts forward a four-wheel drive training mode of "discipline competition + curriculum construction + large innovation project + system guarantee" for college students' innovative ability training mode. This can cultivate college students’ innovative and practical ability in a multi-level and progressive manner, can effectively encourage students’ individualized development, and promote the quality of talent training from "single, closed, and knowledge-instilling" to "complex, open, and innovative "conversion.
