Embodiment Construction

[0022] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0023] This embodiment includes the following steps:

[0024] (1) After the mining TBM equipment has completed the excavation in the construction roadway, disconnect the belt conveyor in the construction roadway, then retract the belt conveyor by 40-45m, and then fire the cannon to expand the dismantling chamber. The equipment along the inner side brushes and expands the disintegration chamber to the rear, and then uses the belt conveyor and rake machine to transport the expanded gangue out;

[0025] (2) First support the side support of the equipment itself on both sides of the roadway, then raise the equipment t...

Abstract

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.

Description

technical field [0001] The invention relates to a mine-used TBM dismantling process, in particular to a mine-used TBM retreating dismantling method. Background technique [0002] The full-face hard rock tunnel boring machine (TBM) is an open tunneling equipment developed by coal mines based on the shield machines used in subways and tunnels combined with the actual conditions of coal mines. The shield tunneling method has a process of starting and receiving, and must Do originating station and receiving station. When TBM equipment is used in coal mines, since the elevation of the coal mine roadway is several hundred meters below the ground, it is impossible to excavate the receiving station directly from the ground and dismantle the shield machine like the subway and tunnel. (receiving station), and build a joint roadway to connect with other roadways, and then use the transportation system to transport the equipment out, which is equivalent to constructing a useless roadwa...
