Abstract
A test device and a test method of fractured rock mass collapse and blockfall and fracture water inrush includes a fractured rock mass preparation device, a water source loading device, a surrounding rock pressurization device and a slide rail, wherein the fractured rock mass preparation device is fixed at one end of the slide rail, and the water source loading device is fixed on the other side of the slide rail. An opening is formed in the rock mass water storage structure, and the size of the opening is adapted to the size of the fractured rock mass; the surrounding rock pressurization device includes one bracket and a pressurization structure arranged below the bracket, and a space for accommodating the fractured rock mass is reserved below the pressurization structure; and the bottom support and the bracket are both movably installed on the slide rail.
