Study On The Destructive Laws Of Water Inrush In Floor And The Catastrophe Model In Mining With Pressure

The inrush water of the coal floor usually is the phenomenon in the coal mine that mine the process problem that meet, particularly on contain the abundant underwater of Ordovician limestone aquifers to contain the water rock strata with at deep department proceeding digging activity, when the deep department mine, this problem seem to be more seriously, through establish the mechanics model of inrush water from coal floor , and establish the catastrophe model of inrush water from floor that break, and to proceeds the analysis and discuss to this model and with the Preliminary application.With the method of Numerical simulation, Many factors that that right influence of floor inrush water broke had been proceed to Orthogonal analysis , and have to out coal floor related expression type for moving with of each factor. At the boundary term of coal seam floor is certain , studing the related regulations of the thickness of floor rock strata, character of rock, Mine ground pressure, water pressure, the inclination of the faults, the angle of the crack to the floor break.
