The invention discloses an underground coal mine atomization flame retarding fire preventing and extinguishing method and system. The method comprises the steps of firstly collecting information of gas parameters, temperature parameters and dust parameters, processing the information by a circuit coordination control panel, and transmitting to a control terminal at the ground by a transmission module via an industrial ethernet ring network; secondly, when the control terminal at the ground sends out an operation instruction, opening a water supply pipeline and a water-soluble fire preventing and extinguishing liquid loading box by a control module, opening a small atomizing pressure pump, conveying water-soluble fire preventing and extinguishing liquid into a whole atomizing pipeline, and pressurizing the water-soluble fire preventing and extinguishing liquid by the small atomizing pressure pump; finally performing atomization flame retarding on an underground key area via atomizers. The underground coal mine atomization flame retarding fire preventing and extinguishing system comprises a carbon monoxide collector, a temperature collector, a dust collector, the industrial ethernet ring network, the control terminal and an atomization flame retarding system.
Description
technical field [0001] The invention belongs to the technical field of coal mining in coal mines, and in particular relates to an atomization, flame retardant, fire prevention and fire extinguishing method and system in underground coal mines. Background technique [0002] With the continuous development of coal mining technology in my country, the comprehensive mechanized mining technology and technology of coal mines have brought greater economic benefits to mines, and at the same time, mine disaster prevention and control are facing new challenges. There are currently many technologies for fire prevention and extinguishment in coal mines, among which spraying chemical inhibitors or using chemical reagents with flame retardant effects is a conventional and practical fire prevention technology for preventing coal spontaneous combustion. The traditional spraying of inhibitors is mainly by manual spraying on the coal surface. The inhibitors can only inhibit the coal at the ba...
