The Design of Web-Based Management Information System
Abstract. Before gas drainage, you must understand the basic information of gas and gas extraction parameters to evaluate the feasibility and economy of coal seam gas extraction, as the basis for design of gas drainage. Gas drainage in coal mining must have the appropriate drawings, records, reports. Based on the current management The visualization function of coal mine safety monitoring GIS system based on Android platform mainly includes GIS map enlargement, reduction, translation, measuring point sensor information query, and alarm and early warning. Its visual function software model is shown in Figure 11. Figure 11.Design and Implementation of Coal Mine Safety Monitoring
