Embodiment Construction

[0021] combine Figure 1 to Figure 5 As shown in the figure, the specific embodiment of the construction method for the fast-opening roadway excavation of the fully mechanized excavator provided by the present invention will be described.

[0022] The utility model relates to a tunneling construction method for a fully mechanized excavator that opens the door quickly, which is suitable for tunnels with fully mechanized tunneling conditions, and can be used in coal and semi-coal rock tunnels, especially in mines with tight excavation connections. In this method, the fully mechanized excavator for coal roadway or semi-coal rock roadway is used to open the door and excavate, and the EBZ150 (160) type of fully mechanized excavator can be used for full-coal roadway or half-coal roadway with a horizontal angle between 90° and 270°. The rock tunnel is opened, and the tunneling orientation of the horizontal turning tunnel in the coal mine is generally calculated by calculating the hor...

Abstract

The invention provides a fast-opening tunnel excavation construction method of a fully mechanized excavator, which relates to the technical field of coal mining. The steps of the method include: A. Determine a large construction drawing, and select the opening position and outline of the roadway; B. Hang a steel wire rope on the roof at the position of the conveyor belt, and the wire rope is connected to the head of the second conveyor belt; C. The fully mechanized excavator follows the The profile is fed according to the large construction drawing at the door opening position, and the direction of the support is aligned according to the center line when the full section is cut; D. Moving with the fully mechanized excavator, lengthening, shortening or moving the second conveyor belt; E .After opening the door, install the three-transport belt conveyor, adjust the position of the wire rope and connect the head of the two-transport belt conveyor. With the advancement of the excavation face, the distance for conveying coal gangue will be extended, and the tunnel will continue to be excavated. The method is used for roadway excavation construction, which avoids the problems of slow construction speed, high labor intensity, and difficulty in gangue excavation.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a construction method of a fully mechanized excavator for fast-opening roadway excavation. Background technique [0002] Insufficient preparations for mine development in the early stage and the impact of the suspension of explosives have caused the mine production to continue to be relatively tense. Especially during the opening period of the roadway, traditionally, blasting construction was first used, and the fully mechanized excavator and belt were installed after 40 meters of tunneling. Fully mechanized excavator (abbreviation for comprehensive mechanized roadheader) is a comprehensive mechanized equipment that integrates various functions of excavation, rock loading, coal transportation, and even support and nailing. The scraper conveyor transports coal, gangue or materials through the open chute, and the scraper is fixed on the chain as a traction member, so that the ...
