The tunnel of Conveyor N° 1 has two ventilation adits one called P-500 and the other P-4600 which divide the tunnel into three separate ventilation sections. These adits were built for the construction of the conveyor tunnel and to divide the airflow in the tunnel in the event of a tunnel fire.
The tunnel ventilation of Conveyor N° 1 is a forced ventilation system with constant flow rate and for the purposes of defining the air velocity the 3 sections ,
2007-7-26 Conveyor tunnel ventilation. We are going to install a reclaim belt conveyor in a concrete tunnel below a crushed iron ore stocKpile.The reclaim is performed automatically by a plow feeder. The presence of personnel is only for inspection and maintenance.
2018-1-17 Longitudinal ventilation is accomplished by using jet fans that, by accelerating a small part of the air present in the tunnel, through an exchange of momentum, are able to induce, on the overall air inside the tunnel, a movement in the willed direction. The same is accomplished for fire smoke propagation control.

2014-4-14 Ideally tunnel ventilation fresh air inlets are located uniformly across the width of the barn end wall opposite the fans. For end wall inlets, two square feet of inlet area per 1,000 cubic feet per minute (cfm) of fan capacity is recommended. For example, a fan delivering 25,000 cfm needs approximately 50 square feet of inlet area.
Our extendable conveyor belt systems for tunnel construction and conventional blasting dispose of excavated material reliably and fast. H+E systems can be extended using assembly trolleys during ongoing operation. This in turn accelerates tunneling performance.
