Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 As shown, a schematic structural view of the parallel operation type fast driving support system of the present invention is provided, which consists of a roadheader 1, a support frame 2, a transport device 3, a bolting drilling rig 4, a front end conveyor 5, and a self-moving machine The tail type conveyor 6 is composed of the roadheader 1 shown for mining coal mines, and the front end transport vehicle 5 is located at the rear end of the roadheader 1 for transporting out the coal mines mined by the roadheader 1 . Self-moving machine tail conveyor 6 is arranged on the rear end of the front conveyor, and is used to further transport coal mines out. The support frame 2 is in the shape of a gantry, and is arranged at equal intervals on the periphery of the boring machine 1 to realize temporary support. The support frame 2 is comp...

Abstract

The invention provides a parallel operation type quick tunneling support system which comprises a tunnel boring machine and a plurality of support frames. The parallel operation type quick tunneling support system is characterized in that the tunnel boring machine is provided with a transporter which is composed of a rack, a front adjusting beam and a rear adjusting beam, parallel conveying chains are arranged on the two sides of the rack, a guide groove is formed in the center of the rack, one end of the front adjusting beam and one end of the rear adjusting beam are hinged to different bases located in the guide groove correspondingly, and beam supporting devices are arranged at the other end of front adjusting beam and the other end of the rear adjusting beam. A construction method of the parallel operation type quick tunneling support system includes the step a of dismounting the support frames, the step b of placing the support frames, the step c of conveying the support frames, the step d of taking the support frames, the step e of mounting the support frames, and the step of of conducting anchor bolt support. According to the tunneling support system and the construction method, hydraulic pressure station legs adopt active support and have a better supporting effect compared with a passive support mode, and safe production is ensured; and meanwhile, an anchor bolt operation drill carriage operates at the rear of the tunnel boring machine, so that parallel operation of tunneling and anchor bolt support is achieved, and coal mining efficiency is remarkably improved.

Description

technical field [0001] The invention relates to a tunneling support system and a construction method in the coal mining process, and more specifically, relates to a parallel operation type rapid tunneling support system and a construction method. Background technique [0002] Currently, the temporary support forms commonly used in domestic coal mines are the two methods of channeling the front beam and pillar plus beam. These two methods all have problems such as longer support time and high labor intensity of workers, which seriously affect the tunneling efficiency when setting up support. The biggest problem is that there are still weak links in safety. The front probe beams, pillars and beams are all passive supports, without active support. The workers are working in the empty roof area. Once they are pressed, they cannot be effectively supported, which brings great hidden dangers to safe production. [0003] At present, the existing domestic hydraulic temporary support...
