Research and application of coal floor water bursting forecast system based on GIS

After having analyzed the factors of the mine flood of the coal floor, studied the theory of coal floor water bursting, and established the model library of mine flood forecast system, we finally designed the coal floor water bursting forecast system and make it to appliance from the surface to the point, with the help of GIS(Geographic Information System) spatial analysis tools and database management platform, and having quantified the Water-rich aquifers, water pressure, aquiclude thickness, the depth of mining damage, and using scientific methods such as the water bursting coefficient, residual analysis, neural network, expert systems and so on. The soft has been tested in WUKUANG of PingDingShan Coal Group bore field after the system completion and the result is good, ensured the safely in production, and liberated the coal seam by the threat of pressure water in the mining area of G₁.
