- W2367224973 abstract "The conception and meaning of the aged coal mine is defined by summing up related names of the aged coal mine and basic conception analysis.In order to set up the criteria for a aged coal mine,the paper choses mine remaining service life as identification standard to identify whether a coal mine is aged or not on the basis of correlation analysis of influence factors.By the cluster analysis method the paper determines the remaining service life criteria for the aged coal mine,and based on which 10 a is the criteria for large and medium-size coal mine and 5 a for small-size.Then the paper put forward a system dynamic model for a coal mine lifecycle which is proved correctly and effectively by fitting test of historical data employing identification standard and influence factors of the aged coal mine.The model can simulate a coal mine lifecycle and reappear the past action characteristics,judge inflection point and predict remaining service life of a mine." @default.
