Based on the same inventive concept, one or more embodiments of the present specification provide a coal seam floor disaster simulation method, as shown in fig. 6, including:
And 603, simulating the disaster of the coal seam floor through the simulated motion of the test main body.
In a specific application scene, the test main body mainly simulates four working conditions, namely a first working condition (water-proof layer thinning type water inrush): coal mining causes the water level of the aquifer to rise along the lift guiding belt to the position of the damage belt, and the water level rises to the water inrush through the rupture of the damage belt. Working condition two (delay lag type water inrush): the coal seam mining causes the water level of the aquifer to rise to a certain height along the leading rising zone and the fault, the state lasts for a period of time, the coal mining water level continues rising through the fault, and the water level slowly rises to water inrush through the fracture zone. Working condition three (instantaneous water inrush): the coal seam mining causes the water level of the aquifer to rapidly rise to the position of a damage zone along the lead-up zone and the fault, and the water level rapidly rises to the water inrush through the fracture of the damage zone. Working condition four (collapse column type water inrush): coal seam mining causes rapid rise of aquifer water through the trap column, at which time water bursts from the coal seam mining site. In a specific test, after the coal bed moves, water in the aquifer grows until the water level of the lift guiding zone changes, the damage zone is broken, and the water barrier becomes thin and breaks through the water burst of the damage zone, so that a first working condition is simulated; after the coal bed moves, water in the aquifer grows to the water level of the lift guide zone and changes, water inrush is delayed through a fault, and the damage zone is broken, so that a working condition II is simulated; after the coal bed moves, water in the aquifer grows to the water level of the lift guiding zone and changes, instant water burst is caused through fault, the damage zone is broken, and therefore the working condition III is simulated; after the coal bed moves, the water level of the collapse column changes due to the development of water in the aquifer, and water inrush is caused at the coal bed mining part, so that the working condition four is simulated.
