Dismantling construction method of underground mine tunnel boring machine (TBM)

Abstract

The invention provides a dismantling construction method of an underground mine tunnel boring machine (TBM). The TBM dismantling construction method comprises the following steps that (1) a dismantling roadway is built, specifically, the dismantling roadway is built in the tunneling direction in front of the TBM, and the dismantling roadway is built till reaching the parking position of the underground mine TBM; (2) dismantling preparation work is conducted, specifically, one end of the dismantling roadway is subjected to expanding excavation so that an expanding excavation section can be formed, and the expanding excavation section is tightly close to one end of a TBM tunneling roadway; and (3) TBM part dismantling construction is conducted, specifically, a TBM main machine and a TBM rear auxiliary system are disconnected firstly, the TBM main machine is driven into the expanding excavation section, and meanwhile the TBM main machine and the TBM rear auxiliary system are dismantled and conveyed onto the ground from the positions from the front and the back of the TBM. According to the dismantling construction method of the underground mine TBM, the TBM is dismantled at an underground mine, TBM dismantling is conducted from the front and the back of the TBM, small machine tools such as a monorail crane and a craning pulley are adopted, and large devices such as a gantry crane do not need to be installed under a well; and the expanding excavation and transforming engineering quantities are small, the dismantling construction period is shortened, and engineering construction cost is reduced.

Description

technical field [0001] The invention relates to the field of underground mine construction, in particular to a method for dismantling and constructing an underground mine full-face boring machine (Tunnel Boring Machine, TBM for short). Background technique [0002] In the underground mine roadway, due to the limitation of the narrow space of the underground mine, the blasting method or the cantilever type roadheader is often used to excavate the underground mine roadway. The blasting method has fewer construction machines and tools, and the construction is convenient and flexible, but the labor intensity is high, the construction risk is high, and the degree of automation is low. The size of the cantilever roadheader is small, but the excavation, slag discharge, and support are carried out step by step, so it cannot realize continuous excavation, and because of its low power, it cannot break hard rock, so it is only suitable for excavation in soft rock formations and coal se...

AI Technical Summary

Problems solved by technology

For underground mines, the depth of burial is generally large. If a shaft is built for disassembly, the construction is difficult and the cost is too high, which makes it difficult to disassemble the TBM after it is excavated in the underground mine, so as to enter the next excavation face; the above-mentioned deficiencies have seriously affected Application of TBM in Underground Mine
