Ventex: an expert system for mine ventilation systems analysis

Mining Technology

United Kingdom

1997

roblems relating to mine ventilation systems analysis are usually of a very complex nature. They involve the estimation of numerous interdependent parameters pertaining to the network status, ventilation status, ventilation system stability, air current losses, climate conditions, gas state, fire risk and dangerous dust pollution risk. The solution to these problems relies, to a great extent, on numerical methods. With the development of computer technology these methods were incorporated as numerical routes in software packages, such as the mine ventilation simulation system, Sim Vent. However, all the potentials of these numerical packages can only be fully exploited by specialists in the field. Besides procedural knowledge encapsulated by numerical routines, the complexity of the subject matter requires a high level of expert knowledge and experience. This knowledge pertains to the heuristics experts use when they apply numerical methods and it takes a symbolic form, very often that of rules, being thus declarative in its character. Hence, both procedural and declarative knowledge are needed for a successful solution of problems in mine ventilation systems analysis. This paper describes an approach to mine ventilation systems analysis which is based on a symbolic upgrading of the numerical Sim Vent system. The result is VENTEX, a coupled expert system incorporating, both procedural and declarative knowledge, that offers the possibility for a more profound exploitation of the available software at an expert level. The paper presents the global strategy of mine ventilation system analysis used in the VENTEX system and its formalisation using a modification of the object-oriented analysis model as well as the basic architecture of the system. The main features of the implemented system are discussed and illustrated by a case study at the Soko brown coal mine in Serbia.
