摘要
The present invention provides an experimental platform for simulating a coal rock disaster of a coal mine extraction, including a base device, a coal simulation device, an immediate roof simulation device, a hydraulic support and a removable impact device. The coal simulation device is fixedly disposed on the base device; the hydraulic support is fixed on the base device and is located at one side of the coal simulation device; the immediate roof simulation device is disposed above the coal simulation device and the hydraulic support; the removable impact device is disposed above the immediate roof simulation device; the immediate roof simulation device is a rectangular frame; the rectangular frame is configured to pave a bulk simulation material and an immediate roof simulation material sequentially from the bottom up; and the removable impact device can impact the immediate roof simulation material and the bulk simulation material.
