    Means of control of the working atmosphere in tunnels characterized by being constituted by three interconnected sub-systems, ventilation (a), gas confinement sub-system (b) and environmental monitoring sub-system (c) where once when the blasting is triggered, and the pressure wave generated by it is released, the gas containment barrier will be closed, the ventilation used will be mixed suction-blower so that all blasting gases return through the suction duct, activating the suction fan (7). ) at maximum power so that the blower ventilation, will have to counteract the flow sucked into the bottom of the bag, so the ventilation stop (3) will be in position in which part of the flow will go to the front, while another part returns through the area before the barrier, through the gallery and the blower flow will be equal to the sum of the aspirant flow plus the flow that returns through the gallery.

    The blower fan (1) that has a frequency inverter (6) in order to control the speed of the same and with it the air flows introduced is controlled by a relay (1) activated by the actuation station (60 ) based on information received from stations (50) and (51).
    The suction means are constituted by at least one suction fan (7) preferably located in the part closest to the outside of the tunnel (T), which sucks a stream of contaminated air through a duct (8) to the outside of the tunnel .
    The aspirating fan, which has a frequency inverter (9) in order to control the speed of the same and with it the aspirated air flows and is controlled by a relay (2) activated by the actuation station (60) based on the information received by the stations (50) and (51).  GAS CONFINING Sub-system (B).
    This sub-system will be constituted by a mobile barrier that can be placed along the tunnel where it is needed and that can isolate the front area, where the blasting takes place, from the rest of the tunnel.
    In this way you can have different ventilation of the front at the time after the blasting, being able to continue the work in the part of the tunnel farthest from the front and minimizing the waiting times and the energy costs of the aspiration of the gases generated in the blasting
    The mobile barrier that the invention advocates would be constituted by a peripherally inflatable barrier (20) so that it adapts to the floor and contour of walls and ceiling, due to its inflatable character with a curtain (21) of vertical enclosure, of strong and unbreakable fabric in solidarity with the inner perimeter of the barrier (20).
    This set would go inside a quick-opening container (22) that would involve two handles (23) for handling and at least four pass-throughs (24), for coupling suction and / or blowing ducts depending on the moment.
    In addition, the container (22) would have a gas control center (25) with meters of all the necessary parameters, that is, to control at least O2, CO, CO2, NO, NO2, SO2 and SH2.
