Embodiment Construction

[0010] A method for constructing a right-angle turn in an underground T-shaped roadway, comprising the following steps: after the first roadway and the second roadway are vertically connected

[0011] The first scraper conveyor is installed in the first roadway; a fully-mechanized excavator is placed on the turning face of the second roadway, and the bridge-type transfer machine is connected to the back of the fully-mechanized excavator, and the tail of the bridge-type transfer machine is connected to the second scraper conveyor.

[0012] The tail of the second scraper conveyor is overlapped with the first scraper conveyor by the third scraper conveyor.

[0013] After a sufficient distance is excavated, the third scraper conveyor is removed, and the second scraper conveyor is overlapped with the first scraper conveyor.

Abstract

The invention relates to a right angle turn construction method of an underwell T-shaped roadway, and the method is as follows: after a first roadway and a second roadway are in vertical cutthrough, the first roadway is internally provided with a first scraper conveyor; an integrated excavator is placed on a turn working face of the second roadway, a bridge reversed loader is connected with the rear part of the integrated excavator, the tail part of the bridge reversed loader is connected with a second scraper conveyor, and the tail part of the second scraper conveyor is in overlap joint with the first scraper conveyor by a third scraper conveyor. After enough distance of tunneling, the third scraper conveyor is dismounted to enable the second scraper conveyor to be in overlap joint with the first scraper conveyor. The method can effectively solve the problem of turning of a T-shaped roadway tunneling machine.

Description

[0001] technical field [0002] The invention belongs to the field of excavation construction of an underground coal mine roadway, and in particular relates to a construction method for right-angle turning of an underground T-shaped roadway. Background technique [0003] When mining underground in coal mines, sometimes the roadheader needs to turn 90 degrees on the spot. After the turn, due to the small space, it is often impossible to directly install the reloader or lay the scraper conveyor to discharge the coal. At this time, workers are often required to work manually, and the work intensity is very high. Big. Contents of the invention [0004] The invention provides a right-angled turn construction method for an underground T-shaped roadway, which solves the problem that in the initial stage of mechanized construction of a right-angled turn in a T-shaped roadway, it is impossible to directly install a reloader and a scraper conveyor, and the coal needs to be manually ...
