Abstract

The invention belongs to the technical field of mining ventilation, and particularly relates to a mine tunnel with good ventilation performance. The mine tunnel comprises a mine tunnel main body, a draught fan connected to the mine tunnel main body is arranged on a pipeline of a ventilation pipeline, in addition, a connecting pipeline penetrating through the mine tunnel main body is fixedly connected to the outer side of the ventilation pipeline, a ventilation aeration pipe is fixedly connected to the lower end of the connecting pipeline, the outer side of the ventilation aeration pipe is sleeved with a plurality of limiting hoops, fixing bolts connected to the mine channel body are symmetrically connected to the outer side of each limiting hoop in a screwed mode, butterfly bolts are connected into the limiting hoops in a screwed mode, and clamping and fixing blocks are connected to the upper ends of the butterfly bolts in a rotating mode. According to the mine tunnel, by arranging thedraught fan, the ventilation capacity can be achieved, meanwhile, the interior of the mine tunnel main body can be ventilated in a large area by adopting the ventilation aeration pipe, the ventilation speed is high, breathing of workers cannot be affected, in addition, the limiting hoops are adopted, the butterfly bolts are rotated, so that the ventilation aeration pipe is pressed and fixed through the clamping and fixing block, and the firmness is high.

Description

technical field [0001] The invention relates to the technical field of mining ventilation, in particular to a mine tunnel with good ventilation performance. Background technique [0002] The mine road is the basic channel for underground ore transportation, and the basic method of ore transportation is to use slope mine roads and trucks to transport it to the ground. [0003] Due to the high cost of the existing mine tunnels, it is impossible to build very wide, resulting in poor ventilation effect, and the breathing of the staff is easily affected. For this reason, a mine tunnel with good ventilation performance is proposed. Contents of the invention [0004] The purpose of the present invention is to provide a mine tunnel with good ventilation performance, which solves the problem that the existing mine tunnel cannot be built very wide due to its high cost, resulting in poor ventilation effect and easily affected breathing of workers. [0005] In order to achieve the a...
