The invention discloses a detachable mine support carrier. The detachable mine support carrier comprises a frame assembly and is characterized in that the frame assembly is integrally U-shaped and comprises a middle box body, a right side frame box body and a left side frame box body, wherein the right side frame box body and the left side frame box body are in mirror symmetry with respect to thecenter line of the middle box body, and the two ends of the middle box body are detachably connected with the front ends of the right side frame box body and the left side frame box body. Compared with the prior art, due to the adoption of a quick disassembling mode, few parts involved in disassembly and assembly are small, only eight bolts are required to be detached, the labor intensity is reduced, and the disassembling and assembling efficiency is improved. The wedge-shaped structure has a self-locking function and can keep effective bearing gravity and traction force.
