Abstract

The invention relates to a continuous driving system for a coal mine laneway. The continuous driving system for the coal mine laneway comprises a front frame, a rear frame, an independent cutting head, a conveyor, a plurality of alley part supporting roof bolter and a top supporting roof bolter, and a remote centralized control station, wherein the front frame comprises a pair of first sliding boots which are arranged in a horizontal mode and in parallel and first supporting frames which are arranged on the upper portion of the first sliding boots, the first sliding boots are correspondingly connected with both sides of the first supporting frames by at least one first supporting oil cylinder, the front ends of the first supporting frames are provided with a plurality of extensible oil cylinders in a horizontal mode, and an extensible end of each of the extensible oil cylinders is horizontally provided with front extension supporting beams; and the rear frame comprises a pair of secondsliding boots which are arranged in a horizontal mode and in parallel and second supporting frames which are arranged on the upper portion of the second sliding boots, the second sliding boots are correspondingly connected with both sides of the second supporting frames by at least one second supporting oil cylinder, and the front ends of the second sliding boots are connected with the rear endsof the corresponding first sliding boots through the thrust cylinder. According to the continuous driving system for the coal mine laneway, the excavating, the conveying the supporting of the roof bolter can be carried out at the same time, continuous circulation is carried out, continuous excavation is carried out, remote control is carried out, and the laneway can be formed only once.

Description

technical field [0001] The invention relates to the field of tunneling operations in coal mine roadways, in particular to a continuous tunneling system for coal mine roadways. Background technique [0002] At present, fully-mechanized excavator and integrated excavator are generally used in coal mine roadway excavation. The fully-mechanized excavator is responsible for the cutting and shaping of the roadway section and the material transportation after cutting, while the integrated excavator is temporarily installed on the basis of the fully-mechanized excavator. The support device and the bolter solve the temporary support of the 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 cover of the step-by-step support. There is als...
