System and method for sealing and pressurizing enclosed facilities via prefabricated modules, plugs, doors, and inserts

A method of sealing and pressurizing a tunnel system, comprising:

• defining at least one first tunnel in a planetary body, the at least one first tunnel defining an opening to an exterior environment and a first slot;
• disposing at least one first plug within the first slot of the at least one first tunnel;
• sealing the at least one first tunnel from the exterior environment;
• performing at least one of pressurizing or depressurizing the at least one first tunnel for individuals therein;
• defining at least one second tunnel comprising a second slot in the planetary body;
• disposing at least one second plug within the second slot of the at least one second tunnel, sealing the at least one second tunnel from the exterior environment;
• performing at least one of pressurizing or depressurizing the at least one second tunnel for individuals therein;
• and
• defining a shaft in fluid communication with the at least one first tunnel and the at least one second tunnel, wherein the at least one first plug and the at least one second plug facilitate the sealing and pressurizing of the tunnel system on the planetary body having the exterior environment comprising atmospheric pressures unsafe for the individuals wherein:
• the at least one first plug and the at least one second plug comprise at least one prefabricated plug including a plurality of frames and sealable doors;
• the at least one prefabricated plug is affixed to the interior of the tunnel system;
• and
• wherein the first slot and the second slot comprise the plurality of frames disposed within the first slot and the second slot and rock bolted to a first tunnel surface and to a second tunnel surface and cemented into the first slot and into the second slot.

A system for sealing and pressurizing a tunnel system, comprising:

• at least one first tunnel in a planetary body defining at least one opening to an exterior environment;
• a first slot defined by the at least one first tunnel;
• at least one first plug within the first slot of the at least one first tunnel, the at least one first plug configured for sealing the at least one first tunnel from the exterior environment;
• a shaft in fluid communication with the at least one first tunnel, wherein the at least one plug facilitates the sealing and pressurizing of the tunnel system on the planetary body having the exterior environment comprising atmospheric pressures unsafe for individuals;
• at least one second tunnel in the planetary body:
• a second slot defined by the at least one second tunnel;
• and
• at least one second plug disposed within the second slot defined by the at least one second tunnel, the at least one second plug configured for sealing and pressurizing of the at least one second tunnel from the exterior environment comprising atmospheric pressures unsafe for the individuals,
• wherein:
• the at least one second plug comprises at least one prefabricated second plug including a frame and sealable doors;
• the at least one prefabricated second plug is affixed to the interior of the tunnel system;
• and
• wherein the first slot comprises a plurality of frames disposed within the first slot and rock bolted to a first tunnel surface and cemented into the first slot.
