Graduation design is the last and most important practical teaching link for undergraduates of this major. It is a systematic summary and comprehensive examination of the basic theoretical knowledge and professional theoretical knowledge that students of this major have learned for four years, aiming at consolidating their knowledge and skills such as calculation, logical reasoning and drawing, cultivating and improving their ability and quality of analyzing and solving practical problems, and enriching their knowledge of production practice. Most teachers will divide the graduation design topics for students according to the practice mine, and simply modify the thickness and output of coal seam, which does not combine the actual needs of students' employment and future work and can not fully stimulate the enthusiasm of students' graduation design.
