specific Embodiment approach

[0049] In a specific embodiment of the present invention, in step 3): first use the lifting pulley 6 to lift and install each sub-component of the TBM host 7; then use the monorail crane 3 to lift and install each sub-component of the supporting system 8 after the TBM; When the monorail crane 3 lifts and installs the TBM post-supporting system 8, the TBM post-supporting system 8 is connected with the TBM host 7 and the flatbed trailer 4 to complete all the installation work of the underground mine TBM. Such as figure 1 As shown, according to the embodiment of the present invention, in the construction steps of the assembly chamber provided, the existing roadway 1 of the underground mine is used as the TBM assembly chamber, and the specific implementation method of expanding the assembly chamber expansion excavation section 2 specifically includes the following step:

[0050] Step 101: First, excavate and assemble the chamber expansion excavation section 2 at the end far away ...

Abstract

The invention provides an underground mine TBM assembly construction method. The underground mine TBM assembly construction method comprises the following steps that (1) chamber assembly is constructed, and an existing roadway of an underground mine and a chamber assembly expanding excavation section serve as a TBM assembly chamber; and the chamber assembly expanding excavation section is formed through expanding excavation of one end of the existing roadway. (2) TBM parts transportation is constructed, TBM parts are placed on a platform truck through a monorail hoist, and a winch connected with the platform truck is pulled to a preinstalled position. (3) TBM parts assembly is constructed, the TBM parts are installed through a lifting pulley or the monorail hoist, and the TBM installation is finally completed. According to the underground mine TBM assembly construction method, the existing roadway is used as the assembly chamber, a vertical shaft is not needed to be re-excavated on an assembly site, and the feasibility of construction is improved; and large scale equipment of a gantry crane and the like are not needed to be installed under the shaft by using small scale installation equipment of the monorail hoist, the lifting pulley, the winch and the like, the work amount of the expanding excavation and transformation is small, the assembly construction period is shortened, and meanwhile the engineering cost is saved.

Description

technical field [0001] The invention relates to the field of underground mine construction, in particular to an assembly method for 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 seams. The formation...
