Benefits of technology

The invention provides a way to quickly deliver clean air to people in a deployed mine refuge from a surface source. This is useful when the refuge is in a hazardous environment and there is no other way to get air. A drilling rig can easily place a borehole close to the shield and a duct can be lowered through the hole to supply clean air. The nose piece of the invention can also include a buzzer or horn to alert the occupants of the shelter when the nasal piece is available to connect to the shelter.

Problems solved by technology

The currently available methods for providing safe atmosphere in mine refuges are limited to those life supporting systems provided prior to the occupancy in an emergency, generally less than 96 hours.
In addition, while provisions are routinely made to identify the location at which mine refuges are located, and often for access to emergency borehole drilling equipment to reach the location, no means of connecting a deployed refuge to reliable external breathing air is known.

Embodiment Construction

[0027]In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration preferred embodiments of the invention. These embodiments are described in sufficient detail to enable those skilled in the art to make and use them, and it is to be understood that structural, logical or procedural changes may be made.

[0028]FIG. 1 refers to one type of current art in mine refuges. In this embodiment the mine refuge, numbered 0110, extends from a ridged container which houses compressed air and oxygen along with a chemical carbon dioxide removal system. The occupants recline in the inflated structure, number 1011, for a period limited by the volumes of supplies provided, typically only 96 hours.

[0029]FIG. 2, another embodiment of the mine refuge, numbered 0210, show a rigid refuge which contains compressed oxygen or chemical oxygen production capacity along with a chemical carbon dioxide removal system. T...

Abstract

A system, device and method for rapid delivery of clean air to occupants of a deployed mine refuge from a surface source after the refuge has been deployed and before the self-contained air has been consumed or before the temperature in the refuge has increased to hazardous levels in which a drilling rig is used to a borehole in close proximity to the mine refuge's underground location and a supply duct is lowered through the borehole to the underground mine near the refuge; upon hearing an alarm sounded by the system, a refuge occupant would exit the refuge, using existing personal breathing protection, to retrieve the duct and connect it to the mine refuge.

Description

BACKGROUND[0001]1. Field of the Invention[0002]This invention relates broadly to providing an atmosphere such that it supports life in spaces that, absent such action, constitute respiratory and / or thermal hazards to person occupying mobile refuges in underground mines. More particularly, this invention relates to methods and apparatus for extending life supporting conditions in mine refuges that have been occupied after an accident.[0003]2. Description of the Related Art[0004]Mine refuges, also known as mine shelters, safe havens, mine chambers and refuge alternatives, are mobile emergency structures designed to isolate occupants from hazardous environments that result from an accident which contaminates the air in the mine such that it threatens survival. As mine refuges are relocated within the mines, their position is noted on mine survey maps to aid in rescue. Current art includes provision for creating and maintaining safe atmosphere inside the mine refuge using self-contained...
