Abstract: A geomechanical fluid-solid coupling testing device for water inrush from coal mine collapse column is disclosed, which comprises a testing bed and a collapse column simulating device, wherein the testing bed has a box type structure with an opening at its top and is provided therein with multiple layers of similar materials in which a tunnel or a mining face can be dug out; and the collapse column simulating device comprises a plexiglass barrel with openings at both its top and bottom, the plexiglass barrel is provided at its top opening with a plexiglass lifting device and a hard plastic baffle, and the plexiglass lifting device is provided with a lifting level which is connected with a lifting rope. It can be used for simulating a construction process in a situation of tunnel digging or coal seam mining, for example, for collecting water inrush omen information, and for studying on surrounding rock mechanics, deformation and collapse column seepage rules during construction, thus facilitating safe construction and early warning in practical engineering.
