The Research On Evaluation Criteria And Method Of Mine Ventilation System Of Jincheng Anthracite Mining Group

Safety, an important subject concerned by all nations, is also the key of coal mine production. In recent years, frequent accidents have restricted coal mine production seriously, caused a great loss on both lives and property. According to a survey, most of the coal mine accidents are mainly caused by imperfect mine ventilation system. The mine ventilation is the foundation of creating regular production environment and safety production condition, and also is the basic safeguard of mine production. The ventilation system evaluation can ensure the system rational and stable, prevent the system from disaster.According to the demand of Jincheng Anthracite Mining Group, according to the definition of the mine ventilation system and referring to economic and safety requirements, assessment indexes are determined and systematic and scientific assessment index system is formed,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. The method has been applied to evaluate the ventilation system of ChangPing coal mine and gained good effect in practical application.
