EXTENSION AND FUZZY METHOD IN EVALUATING THE ENGINEERINGQUALITY OF ROCK MASSES IN UNDERGROUND MINING
地下采矿工程岩体质量可拓模糊评价方法

Combining extenics with fuzzy mathematics, the extension and fuzzy method for evaluating engineering quality of rock masses is put forward. The evaluating model with multi index parameters is established, and with the Monte Carlo method, the fuzzy probability of classification of rock masses quality is given. Lastly, the application of evaluating method is shown.
