Method for quickly tunneling shed type supporting roadway

Abstract

The invention discloses a method for quickly tunneling a shed type supporting roadway, which depends on mutual coordination among five big main apparatuses, namely a monorail crane roadway supporting platform, a cantilever type tunneling machine, a reversed loader, a stretchable belt conveyor and a monorail crane, and finishes the processes such as cutting, loading, conveying, supporting and paving in the tunneling construction of the shed type supporting roadway with a higher degree of mechanization. The monorail crane roadway supporting platform is hung on a special-purpose railway, the monorail crane is hung on an auxiliary conveying railway, the combination of the monorail crane roadway supporting platform and the monorail crane can realize mechanized transportation of head-on required materials, tools and apparatuses; a forepoling mounting beam lifts a top beam so as to serve as a temporary support, which not only reduces labor intensity but also reduces time consumed by the supporting process; the working platform is used as the platform of a roof and a two-side high-position operation, and thus optimizes construction condition; an auxiliary conveying system is convenient and fast to construct. The method increases the safety of the tunneling construction of the shed type supporting roadway, improves the starting up rate of the tunneling machine, and reduces the labor intensity.

Description

technical field [0001] The invention relates to a rapid excavation method for a shed-type support roadway based on a monorail crane roadway support platform, which belongs to the comprehensive mechanized excavation technology of coal mine roadways. Background technique [0002] Due to its advantages of being reusable, not prone to instantaneous collapse, and obvious roadway pressure performance, shed support is still the main support method for roadways in some mining areas in my country, especially in areas with complex geological conditions. Compared with the traditional drilling and blasting method, the tunnel comprehensive mechanized tunneling with the cantilever type roadheader as the core has obvious technical advantages. At present, my country's coal mine roadway mechanized excavation technology is in the stage of accelerated promotion and application, coal roadway and semi-coal roadway mechanized excavation technology has been widely popularized, and the proportion o...

AI Technical Summary

Problems solved by technology

[0003] 1. The preparation process (such as the support equipment and support material handling required for the head-on excavation, etc.) is time-consuming and laborious;

[0004] 2. Most of the temporary support is in the form of point columns or front probe beams, which have not realized mechanized operation and low safety;

[0005] 3. Most of the shed beams are erected by manpower, with low degree of mechanization and high labor intensity;

[0006] 4. The support work on the roof and the high positions of the two gangs is mostly carried out on the floating coal (gangue) or the cutting head of the roadheader. The conditions are poor and there is no stable operation platform;

[0007] 5. The auxiliary transportation of the rear road mostly adopts rail transportation, which is slow in laying, high in labor intensity, long in operation line, difficult in management and easily affected by the floor drum, which increases the amount of renovation work and restricts auxiliary transportation
