Design of Fire Prevention and Control in Underground Mines
Abstract
The safe operation of underground mines is not only related to the economic prosperity of the enterprise, but also to the safety of the miners. Therefore, fire prevention and control in underground mines is of great importance. This paper will briefly introduce the characteristics of fires in underground mines, the destructive forces of various types of fire and the common methods of fire prevention and control in underground mines.
I. Introduction
Underground mining is an important part of the mining industry, but due to it operations in enclosed spaces, underground mines are highly susceptible to the threat of fire. Fire in underground mines is an inevitable problem, which not only causes huge economic losses to the enterprise, but also threatens the safety of the miners. Therefore, fire prevention and control in underground mines has become an urgent problem to be solved.
II. Characteristics of Fires in Underground Mines
Underground mining operations typically take place in enclosed spaces, typically tunnels, quarries, and deep mining sites. These sites are not only far away from the natural air supply and packed with combustible materials, but their various systems and production activities make the fire easily spread and prolonged.
In addition to the narrow space, low visibility and lack of oxygen, the intensity of a underground fire is often higher than that of a surface fire because of the rich combustible materials in the surrounding coal seam. In addition, due to the inlet and outlet of air, the flame of a underground fire is much stronger and can hold its own for a long time.
III. Impact of Fires in Underground Mines
Fires in underground mines can cause huge losses of mining machinery and property, and threaten the safety of miners. In addition, due to the poor working environment and poor fire rescue conditions, the fire is difficult to extinguish and the environment is easy to deteriorate. Therefore, the prevention and control of fire in underground mines must be taken seriously.
IV. Fire Prevention and Control in Underground Mines
1. Fire Prevention
(1)Strengthening management. It is necessary to strengthen the management of fire sources, strictly control the ignition sources, and standardize the management of possible fire sources. In addition, it is also necessary to strengthen the management of combustible materials, reduce the amount of combustible materials, and prohibit the accumulation of combustibles such as smuggled items in the production area.
(2)Use of fire-resistant material For buildings and machines with high fire hazard, it is recommended to use flame-retardant materials such as aluminum foil, steel plate and plastic plate.
(3) Fire separation It is necessary to set up walls, floors and ceilings that can prevent the spread of fire and form a Fire-resistant partition, and take other measures to prevent the spread of fire.
(4) Strengthening inspection. It is necessary to increase the frequency of inspections, check potential fire hazards, and take timely measures to eliminate potential fire hazards.
2. Fire Control
(1) Water cooling and smothering. Fire objects and the materials around them can be cooled and smothered with water, turning the fire into a cold object.
(2) Blanket and foam. Blanket or foam can be used to cut off oxygen supply around the fire object, and the fire can be extinguished.
(3) Fire resistant cone. A fire resistant cone can be used to block the flame, soot and smoke discharged by the fire object, preventing the spread of the fire.
V. Conclusion
The prevention and control of fires in underground mines is of great importance. To ensure the safe operation of underground mines, it is necessary to strengthen fire prevention and control, reduce the losses caused by fires, and protect the safety of miners. In short, all the precautions must be taken seriously to ensure the safe operation of underground mines.
