Coal mine tunneling not only affects the speed of coal mining, but also the quality of coal mining. Therefore, it is necessary to ensure the smooth progress of coal mine tunneling construction, and coal mine tunneling requires the use of roadheaders.

[0003] The tunnel boring machines currently used include a walking mechanism, a cutting mechanism, a transfer mechanism, and a spraying mechanism, which can crush coal rocks and transfer them to the outside of the tunnel. At the same time, the spraying mechanism can be used to reduce the impact of flying dust during the cutting process. However, long-term cutting operations will cause a large amount of flying dust to accumulate inside the tunnel boring machine cab, affecting the use of the tunnel boring machine and the operator's vision. For this reason, we propose a coal mine tunnel boring equipment for mining engineering. Utility Model Content
