Research on the Influencing Factors and Adaptive Fuzzy Argumentation of the Main Inclined Shaft Development in Inner Mongolia&Shaanxi Mining Area
To study the feasibility of developing long-distance gentle slope main inclined shafts in large coal mines,a sys-tematic research approach was adopted,which included field visits,data retrieval,statistical analysis,and theoretical calcula-tions.The results indicated the following:(1)The main factors influencing the choice of shaft development method can be cate-gorized into four types:geological conditions,construction conditions,safety conditions,and economic and social benefits;(2)Economic benefits are positively correlated with production capacity and negatively correlated with shaft depth.Generally,gradual inclined shafts have relatively good benefits,but as the depth of development increases,the cost difference between the two de-velopment methods gradually narrows;(3)Comprehensive evaluation of the fuzzy mathematical evaluation system with three layers and fifteen indicators shows that when increasing production capacity,gradual inclined shafts have more advantages in terms of in-vestment and construction period.
