Roadway continuous tunneling system and method

Abstract

The invention discloses a roadway continuous tunneling system. The roadway continuous tunneling system includes a cutting assembly, a support bracket assembly, a bolting machine assembly and a transport transfer machine assembly. The cutting assembly is pushed forward by the support bracket assembly and used for cutting a coal wall, and the cutting assembly is connected to the transport transfer machine assembly to transport cut coal sheets away through the transport transfer machine assembly. The support bracket assembly includes a front frame, a rear frame and front frame pushing oil cylinders. The front frame pushing oil cylinders extend forward to push the front frame to move forward, and the front frame pushing oil cylinders retract to pull the rear frame to move forward. The boltingmachine assembly is mounted in inner space of the support bracket assembly for supporting a roof and side walls. The transport transfer machine assembly is mounted along the bottom of the support bracket assembly. The invention further discloses a tunneling method. The roadway continuous tunneling system and method have the advantages of short support time, continuous tunneling, support while tunneling and high work efficiency.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a roadway continuous excavation system and a method thereof. Background technique [0002] At present, fully mechanized excavators and all-in-one excavating, anchoring and protecting machines are commonly used in coal mine roadway excavation. Fully mechanized excavators are responsible for cutting and forming roadway sections and transporting materials after cutting. The all-in-one excavating, bolting and protecting machine is based on the fully mechanized excavating machine and is equipped with a temporary support device and a bolter to solve the temporary support of the head-on roof of the roadway and the fixing of the anchor net. In addition, it is more cutting-edge to change the temporary support on the comprehensive excavator to a step-by-step advanced support system to solve large-scale and large-area support. The fully-mechanized excavator works independently under the cove...

AI Technical Summary

Problems solved by technology

The cutting drum of the equipment is installed on the front bracket and moves forward together with the front bracket, so the cutting drum has poor flexibility and has relatively high requirements on the front bracket, which requires strong support from the front bracket and the top plate

In addition, the bolter is installed at the end of the rear bracket, and the space between the front bracket and the rear bracket lacks timely support for the bolt, which increases the requirements for the front bracket and the rear bracket.
