The invention discloses a mining TBM receding type dismounting method. After tunneling of mining TBM equipment is completed in a construction roadway, brush expansion is backwards conducted on a disassembly chamber along the equipment in the construction roadway of the mining TBM equipment; side supports of the equipment are supported on the two sides of the roadway firstly, then the equipment lifts rear supports, then a propelling oil cylinder of the equipment draws back to drive a machine body to entirely backwards recede by a step distance, finally, the rear supports are placed down, the side supports are taken back, thus one receding cycle can be completed, and through reciprocating receding, the entire equipment can recede into the disassembly chamber; and the mining TBM equipment is dismounted in the disassembly chamber, and parts after disassembly are conveyed out of the construction roadway. The mining TBM receding type dismounting method is easy to construct and convenient and easy to achieve; and through an existing construction roadway, brush expansion is conducted, the equipment is dismounted and conveyed out, a transferring connecting roadway can be omitted, and thus construction cost is reduced.
