Embodiment 1

[0035] Such as Figure 1-Figure 5 As shown, the present embodiment proposes a rescue equipment for pipe jacking 2 in collapsing coal mine tunnels, including a body 1, several pipe jacking 2, a main jacking mechanism 3, a main jacking mechanism track 18 and a material delivery track 21, wherein the body 1 and the jacking The pipe 2 is movably installed on the rail 18 of the main jacking mechanism. The body 1 includes a cutter head 7 arranged at the front end of the body 1 and a driving device for driving the cutter head 7 to rotate. , the head end of the jacking pipe 2 group abuts against the tail end of the body 1, and the main jacking power end of the main jacking mechanism 3 abuts against the tail end of the jacking pipe 2 group, so as to push the body 1 along the main jacking mechanism through the jacking pipe 2 Track 18 moves forward;

[0036] The ground inside the jacking pipe 2 is provided with a slag truck track 11, and the two ends of the slag truck rail 11 are respec...

Embodiment 2

[0046] This embodiment proposes a pipe jacking 2 rescue method for a coal mine collapsed roadway, using the pipe jacking 2 rescue equipment for a coal mine collapsed roadway in Example 1, including

[0047] Arrangement: After a collapse accident occurs in the mine roadway, the main roof mechanism 3 is quickly transported to the site of the mine collapse accident, the main roof mechanism track 18 is arranged along the direction of the collapsed roadway, and the body 1 is placed on the main roof mechanism track 18. Carry out jacking in the direction of the track, place electric control equipment 4 and grouting equipment at the rear end of the main jacking equipment, and after the jacking pipe 2 rescue equipment is transported in place, arrange the pipe jacking 2 delivery track 21 on the side of the main jacking mechanism 3, and the pipe jacking 2 and the slag truck 16 is transported through the material delivery track 21;

[0048] After the arrangement is completed, jacking and ...

Embodiment 3

[0051] Generally speaking, the rescue equipment for pipe jacking 2 is composed of main jacking mechanism 3, electronic control equipment 4, pipe jacking 2, machine body 1 and grouting equipment. The whole set of equipment is arranged along the direction of the collapsed roadway. On the front side, the body 11 is placed on the upper end of the track 18 of the main top mechanism. The main top mechanism 3 realizes the positioning of the direction of the machine head through the tube clamp 19. The main top mechanism 3 adopts a self-supporting rear outrigger device 20. The material delivery track 21 is arranged on the material delivery track 21, and the transport vehicle 17 is arranged on the material delivery track 21, which is used for the transportation tool pipe and the slag transport vehicle 16. The electric control equipment 4, the grouting pump 5, and two mud mixers 29 are arranged on the rear side of the main jacking device and grouting tank.

Abstract

The invention relates to the technical field of rescue of a mine collapse roadway, and provides jacking pipe rescue equipment for the coal mine collapse roadway. A machine body and jacking pipes are movably arranged on a main jacking mechanism rail; the machine body comprises a cutterhead arranged at the front end of the machine body and a cutterhead driving device driving the cutterhead to rotate; the jacking pipes are in end-to-end butt joint one by one to form a jacking pipe group; the head end of the jacking pipe group is abutted against the tail end of the machine body; a material conveying rail is arranged outside the machine body, the plurality of jacking pipes and a main jacking mechanism; and the material conveying rail is arranged in a way of extending from the positions of the jacking pipes to the outside of the roadway, so that carbide slag cut by the cutterhead can be conveyed to a slag conveying vehicle through a scraper conveyor, and is transported out of the roadway through a slag conveying vehicle rail and the material conveying rail. The equipment can solve the problems of low slag discharging efficiency and the like. The invention also provides a jacking pipe rescue method for the coal mine collapse roadway.

Description

technical field [0001] The invention relates to the technical field of mine collapse roadway rescue, in particular to rescue equipment and methods for coal mine roadway collapse. Background technique [0002] At present, there are two main methods of mine collapse roadway rescue in my country: 1. manual obstacle removal, and 2. large-aperture drilling rigs. These two excavation methods have their own limitations. [0003] First, the manual obstacle removal method refers to the manual use of auxiliary tools such as vibratory hammers and rock drills to crush and remove the collapsed slag, and use simple support methods such as wooden beam brackets to support the collapsed roadway. The method of clearing obstacles and side support realizes the construction of a rescue channel in the collapsed roadway. [0004] Second, the large-diameter drilling technology of domestic mines generally adopts the rotary drilling process method, and the large-diameter rescue hole needs to adopt a...
