Aiming at the shortcomings of one-sided indicator system and strong subjective factors in the current stage of comparison and selection work of coal mine general drawing schemes,a theory of general drawing scheme comparison and selection based on the"total factor"indicator system is proposed.Taking the general drawing scheme comparison and selection of Hujiata Coal Mine as an example,the concept of the total factor indicator system is defined,and based on this,a collection of total factor of the general drawing scheme of Hujiata Coal Mine is established.Then,mathematical models such as Analytic Hierarchy Process(AHP),Fuzzy Comprehensive Evaluation and others are applied to evaluate the general drawing scheme of Hujiata Coal Mine,and the optimal scheme is obtained.
