Research On Application Of Fuzzy Mathematics In Geological Engineering

This article lists the fuzzy phenomena in geological engineering administrative system and makes analysis on the objective origins. From the viewpoint of that the knowledge body of human beings possesses fuzzy properties, the article sets forth the obfuscations that are encountered in treating fuzzy problems in geological engineering administration with traditional mathematics, demonstrating the feasibility that fuzzy mathematics is used in geological engineering administration. The article introduces the basic concepts and common methods of fuzzy mathematics, initially discussing the applications of fuzzy mathematics in the following aspects: 1) Division of "skidding" strata with grade of membership that are drilled with diamond bits; 2) Comprehensive evaluation on the application in evaluation of diamond bits, classification of rock drillability, and evaluation of clay; 3) Classification of "hard rock" through fuzzy clustering analysis; 4) Estimation of completion time of boreholes and evaluation of underground water with fuzzy mathematics; 5) Identification of new ore areas and option of best water resource area with fuzzy model; 6) Option of diamond bits and evaluation on oil field development plan with fuzzy resemble option and the improved calculation method;?) Prediction of mud slurry performance and of the amount of surging water in ore pits with fuzzy control; 8) Comprehensive evaluation of diamond bits and supporting plan of deep foundation pit with fuzzy optimal theory.
