Abstract: According to the special mining conditions of sharply-inclined and thin ore-body in the alpine high-altitude area, based on several conventional mining methods for sharply inclined and thin ore-body, and taking the 11 factor indicators that impact mining method into consideration, the weight matrix of corresponding mining method is calculated out with the use of analytic hierarchy process.Meanwhile the linear functions and the binary comparison sorting method are adopted to determine the index membership matrix, building a comprehensive evaluation index model.It is concluded that medium-hole mechanized mining method with subsequent waste rock filling is superior, and the heavy labor problem in Qinghai Plateau is solved as well.

Key words: Alpine high altitude, Sharply-inclined thin ore-body, Mining method, Analytic hierarchy process, Comprehensive evaluation index model
