| The mine ventilation is the foundation of creating regular production environment and safe production condition, and also is the basic safeguard of mine production. The ventilation system evaluation can ensure the system rational and stable and prevent the system from disaster. In order to provide against accidents at the angle of the system rationality, the normative ventilation system evaluation method is studied and selected, and the evaluation index system and the index quantified method are established and the evaluation grades has been quantified in this paper. By establishing the mathematic model of the system evaluation, the ventilation system in coal mine is evaluated synthetically. For the system valuation index system is complex, coal mine ventilation system valuation software is developed based on Visual Basic. The software has beem applied to evaluate the ventilation system and gained actual application effect. |
