GIS-based mine ventilation network and safety analysis

The paper constructed the mine ventilation network model using the powerful function of attributes management, display visually and spatial analysis of GIS based on the character study of GIS and mine ventilation network. The mine ventilation network model we put forward in this paper is a COM-based extension of the Geo-network of ArcInfo. In mine ventilation network model, specified result can be obtained by defining weigh values for attribute fields as the constraint condition. It is of great importance for mines to determine the best rescue and leaving route by mine ventilation network route analysis, node analysis and loop analysis when mine accident happens. By the mine ventilation network model we put forward in this paper, the best rescue and leaving route can be implemented in a short time. The research achievement is used successfully in ShiGejie mine, Shanxi Province of China. The application result shows the feasibility of the study achievement
