Abstract: In view of the waste of space resources and the serious shortage of oil reserves in abandoned mine tunnel, the idea of using that to store oil is put forward. This paper selects three first-level evaluation indicators: development conditions, geological conditions, groundwater conditions, and 11 secondary indicators. The evaluation system is established by using the analytic hierarchy process, and the feasibility evaluation model of oil storage by using the abandoned mine tunnel is constructed by using the fuzzy mathematics comprehensive evaluation method. Analytic hierarchy process and fuzzy mathematics comprehensive evaluation method are used to evaluate the feasibility of oil storage in abandoned mine tunnel in Baijiazhuang Mine. The results show that geological conditions have the greatest influence on the feasibility of oil storage in abandoned mine tunnel, and the weight is 0.65. The impact of groundwater conditions takes second place, the weight is 0.23. Development conditions have the least influence, with a weight of 0.12. The results of comprehensive evaluation on the feasibility of oil storage in abandoned mine tunnel in Baijiazhuang Mine is moderate and in line with the actual situation. The feasibility evaluation results of oil storage in abandoned mine tunnel in Baijiazhuang Mine are consistent with the practice, which proves that the evaluation model established can objectively, scientifically and accurately evaluate the feasibility of oil storage in abandoned mine tunnel, and provides a reference for the theoretical research of the exploitation and utilization of underground space resources in the abandoned mine.
