Abstract

One or more embodiments of the invention provide a coal seam floor disaster simulation device and method. The coal seam floor disaster simulation device comprises a simulation box and a control mechanism. The simulation box is used for bearing a test main body, and one side of the simulation box is provided with an observation window; and the control mechanism is arranged on one side, opposite tothe observation window, of the simulation box and is used for controlling the test main body. According to the one or more embodiments of the present specification, the geological structure mainly encountered in the existing coal seam mining is simulated through different test main bodies, the coal seam mining is simulated through the control mechanism, and the simulated geological change situation is observed through the observation window. The whole device has the advantages of being simple in structure and easy to observe, can visually and vividly simulate the mechanism of disaster formation caused by water inrush of the bottom plate in the coal seam mining process, can accurately predict and early warn disasters according to simulation; and meanwhile, the device is beneficial to rescueand repair after disasters.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of coal mining, and in particular to a coal seam floor disaster simulation device and method. Background technique [0002] In recent years, with the advancement of science and technology, the equipment, technology, and technology in the production and construction of coal mines have been greatly improved, but coal mine accidents, especially water inrush accidents from the coal mine floor, still occur frequently. The essence of water inrush from the coal seam floor is that the underlying pressurized water in the coal seam breaks through the barrier of the floor water-resisting layer along the internal channel of the rock mass of the floor water-resisting layer of the coal mining face, and rushes upwards into the working face in the form of burst, delay or delay. process of empty space. [0003] However, traditional water inrush prediction methods do not take into account spati...
