Safety Standardization Evaluation System of Tailing Reservoir Based on Analytical Hierarchy Process

In order to reasonably evaluate safety standardization grade of tailing reservoir, after consulting relational laws, statutes, technical standards and criterions, the paper put forward a safety standardization evaluation system of tailing reservoir which uses 9 first level indexes and 38 second level indexes to estimate safety performance of tailing reservoir and uses analytical hierarchy process to define weighing value of every index. The actual application showed that the system can reflect reality of tailing reservoir more realistically and objectively.
