The Concept and Study of Initial Exploration of Life-saving Food in Coal Mining

After a coal mining accident, the key to the success of the coal mining emergency rescue is that the trapped miners are still alive before the rescue passage are made through. As new life-saving equipment, life-saving foods are used to maintain the viability and the self-saving ability of the front-line miners when they are trapped in the coal mining accident. The life-saving food will effectively extend the self-save time for the trapped miners and then essentially improve the rescued possibility of the trapped miners. The amount of human metabolism, which was measured under the hot and humid environment, determines salt targets and nutrition indexes of the life-saving food. According to the particularity of underground environment, the passage explores the method to store the life-saving food and how to reasonably select the storage locations. Reviewing the application of the mine life-saving food, we can conclude that the self-saving food will have a better future in the economic and social aspects. But it still needs to be demonstrated whether it is necessary to carry the food with the human body. When the life-saving food is exposed under the hot and humid environment, the deterioration cure is still unclear.
