Research On The Damp Disaster Information System Based On WebGIS

Safety in coal mining is the most important thing in the safety of contemporary production, and damp disaster is the most severest natural catastrophe menacing coal mining safety . Along with the development of the computer technology and the technology of damp disaster forcast, an integrated damp disaster information system which combines these two kind of technology can help to forcast the damp disaster of the coal mine, which holds great practical meaning to the safety in the coal mining.In this thesis, the technology of damp disaster forcast is firstly been researched. In this reseach of Damp disaster, we mainly study gas explosion and burst of coal and gas, analyze gas explosion with the accidental tree of gas explosions, and get the conclusion that damp concentration is the most important factor of gas explosion; according to the experts in and abroad, the influential elements of the burst of coal and gas, which can be divided as the geographical characteristic of coal bed and the sensitivity of burst, is analyzed; combined with the BP neural network, the model of damp concentration forcast and the model of forcasting coal and gas burst is established and verified.Then, we analyzes the demand and the target the system, the integrated structure of the system, the function of the system, the database of the systme and the operational enviroment of the system. Applying TopMap geographical information system as the development platform and C# as the development language, combining with the model of damp concentration forcast, with the technology of web programming, the technology of database and the theory of sofeware engineering, we establish a damp disaster information system based on WebGIS and describe in detail every functional module of the model and how to realize them. Finally, to verify the funtion of the system, a coal mine is taken as an example.
