MINE DOORS & PEDESTRIAN DOORS
AMD offers five different models of ventilation doors that are used in underground mining operations. Ventilation doors are used to exhaust gases, direct airflow or create an air lock.
Models vary from low pressure (smaller size doors) to high pressure (larger size doors).
AMD® engineering calculates the amount of force placed upon the proposed door, using water gauge, height, and width to determine the amount of torque. Once we determine the amount of force (the more surface area and the higher the water gauge, the more force required to open and close the door), we advise each customer on the proposed door model and construction.

AMD Offers a full line of insulated and non-insulated roll-up doors for UG mining and surface mining applications. We also offer fire and smoke rated roll-up doors.
Roll-up doors can be used at the surface or underground: travel doors, service bays, battery charging bays, maintenance bays and fire doors.
Fire and Smoke Ratings on Roll Up Doors.
All mining operations must adhere to specific requirements when it comes to fire safety. Mines regularly house hazardous and highly-flammable materials, making fire doors a necessity in some areas.
We regularly work with customers across the United States and around the world to customize durable, dependable fire doors for all types of mining operations.
Heavy-Duty Heat Protection
Our fire-rated mine doors are designed with heavy-duty, flame-retardant materials for added protection in the event of a mining emergency. These doors close and latch automatically, to prevent them from being left open during a fire.
Fire doors can be used to compartmentalize fires in various mining environments, quickly containing both flames and smoke while personnel are evacuated. The most common types of fire doors include:

Powder Magazine Doors
Type 1 Explosives Magazine Security Door & Type 2 Outdoor Magazine Security Door
AMD has designed and built these specialty doors that are required to meet the ATF’s Explosive Magazine Construction Requirements, 18 U.S.C , 27 CFR, Part 555, Subpart K-Storage.
We design and manufacture manual and automatic Explosive Magazine Doors that meet “TYPE 1 Magazines” as specified by the ATF. The Type 1 Magazine is the most stringent of the 5 different types of “Explosive Magazine Doors” designated by the ATF.

Mine Door with Built in Dampers
AMD offers both parallel blade and opposed blade dampers, dependent upon type of application. Most mines use OPPOSED blade design.
As a very general rule, parallel blade dampers are used for open/closed operation and opposed blade dampers are used for modulating damper operation. However, parallel blades offer better control of airflow near the end of the operating range (near full open or full close positions). Opposed blades offer better control of airflow throughout the entire operating range.
