| The mining operation of ores of gently inclination is generally regarded as a challenging technical problem in the industry. As the technology of mining engineering develops, the process of selecting and applying the mining method of gently inclined ores changes simultaneously, ending up with a leap of the percentage that cut and fill mining in the application of all mining methods. The generalization of computer simulation technology in the industry prompts the trend of comprehensive application of computer science in every aspect of mining engineering. Based on the data collected during the operation of a tin & tungsten ore in Lushui, Yunnan, this paper completes the work of conducting a optimization of schemes utilizing FLAC3D, MATLAB, etc. The result of this paper is based on the analog outcome of a series of models made on the principle of safety, economy and rationality. The contents of this paper are:(1) Collecting data of a tin & tungsten ore in Lushui, Yunnan and similar mines, established the economic index system of mining methods.(2) Established the preliminary selection of mining method by comparing performance of different methods in the simulation model built with collected data.(3) Generating a three-dimensional finite-difference model of the selected mining method, analyzed the stability of stope.(4) Conducted a fuzzy math simulation based on analytic hierachy and the analog result of previous processes.(5) Optimized schemes based on the simulation, guided the production process of the bargh.
