Mine laneway disaster prevention water wall

Abstract

The invention relates to a coal mine roadway disaster prevention water wall. The wall comprises a water wall body, a flameproof fabric and a pressure valve, and is characterized in that the water wall body has a multi-air bag structure formed by jointing polyurethane lining fire fighting water hoses; and the flameproof fabric is made of light material with a low heat conductivity coefficient and comprises an inner layer which is a heat resistant airtight layer and an outer layer which is a flame retardant and fireproof layer coated with conductive strips, and, therefore, can prevent fire and static electricity effectively. When a disaster occurs, the wall water can be filled with water immediately to expand to close a roadway and to prevent fire extension, gas explosion or harmful gas diffusion to control the disaster quickly and effectively. The disaster prevention water wall is simple in structure, low in price, convenient in transportation, quick in installation, safe in operation and repeated in use, and can close undermine roadway conveniently, prevent escalation of the disaster, quickly, effectively control the disaster and win time for coal mine rescue.

Description

Technical field [0001] The invention relates to a mine roadway disaster prevention water wall, more specifically a mine roadway disaster prevention water wall for preventing underground fire from spreading, gas explosion or harmful gas diffusion. Background technique [0002] At present, the closed walls of the mine roadway are all made of stones and cement, and the temporary closed wall is made of wooden boards, that is, a few wooden piles are driven in the roadway that needs to be closed, and the wooden boards are nailed to the wooden piles, and then nailed on the surface of the wooden boards. The fireproof cloth is put on to form a temporary closed wall. In the construction and demolition process of this method, the preparatory work is large, the material consumption is huge, the implementation time is long, the operation is dangerous, and the sealing effect of the closed wall is poor, and the air leakage is serious. The main disadvantage is that when a fire, gas explosi...

Problems solved by technology

In the construction and demolition process of this method, the preparation work is heavy, the material consumption is huge, the implementation takes a long time, the operation is dangerous, and the sealing effect of the closed wall is poor, and the air leakage is serious.

The main disadvantage is that when a fire, gas explosion or harmful gas spreads underground, emergency measures must be taken to seal the accident site. This method cannot quickly build a closed wall, cannot meet the needs of quickly and effectively controlling the disaster, and cannot resist disasters for the mine. rush to buy time
