A Research Of Expert System About Medium-depth Holes Blasting Design Of Underground Mine

Taking the medium-depth holes blasting of underground mine in Chengchao Iron Mine as engineering background, on the basis of the knowledge representation method of mineral blasting and the structure of knowledge base, the author adopts the technology of object-oriented programming and the idea of modularization on the Delphi platform. A practical expert system of medium-depth holes blasting design of underground mine is developed by synthetically using the principle of expert system, the technology of artificial neural network, the theory of fuzzy control and the method of database foundation.Meanwhile, according to the applying conditions of KUZ-RAM Model, an equivalent transformation from parallel holes to fan-shaped medium-depth holes is also put up to apply the KUZ-RUM Model in open mine to underground mine. Combining with the relation between the R-R distributing curve and the real measured block distributing curve, the KUZ-RAM mathematics model is amended and some main calculation formulae of blasting parameters in Chengchao Iron Mine are established by applying the field data directly. At last detailed introduction about the expert system' s function and its use is given through a practical implementation, which proves that the prognostic results are in accordance with practice and thus an effective means is put forward for the blasting design, block controlling and production management of underground mine.
