Automatic mining gel foam fire preventing and extinguishing system and using method

Abstract

The invention discloses the technical field of coal mine underground coal spontaneous combustion and ignition prevention and control and particularly provides an automatic mining gel foam fire preventing and extinguishing system and a using method. The automatic mining gel foam fire preventing and extinguishing system comprises a mixed foaming module, detectors and a control module, when a coal mine underground fire disaster happens, the detectors give an early warning response and transmits an early warning electric signal to the control module, the control module triggers foam electromagnetic valves in a fire disaster occurrence area and an electromagnetic valve for controlling a power source and starts a mixed foaming device at the same time, gel foam is sprayed out through spraying gun bodies to extinguish fire, meanwhile, the control module outputs an early warning electric signal to a coal mine fire disaster alarm module, a coal mine fire disaster alarm system sends out an alarm signal, and ground workers know the position of the fire disaster at the first time, prompt related operators to escape in time when the fire disaster occurs and take corresponding measures. The automatic mining gel foam fire preventing and extinguishing system has the characteristics of high efficiency, simplicity, convenience, easiness in maintenance, high reliability, intrinsic safety and the like, and the functions of automatic alarm and automatic fire extinguishing at the initial stage of the coal mine fire disaster can be realized.

Description

technical field [0001] The invention relates to the technical field of underground coal mine prevention and control of coal spontaneous combustion, in particular to an automatic mine-used gel foam fire prevention system and a use method. Background technique [0002] As the primary primary energy source in my country, coal plays an important role in the development of the national economy. Especially in recent decades, with the vigorous promotion and application of fully mechanized top coal caving technology, the production efficiency of coal mines has been greatly improved. Flames more frequently. In addition, the coal spontaneous combustion fire area in the goaf is spatially distributed, and the fire source is relatively hidden and difficult to identify, resulting in a lag in the discovery and adoption of fire prevention measures, delaying the best time to put out the fire. In view of the characteristics of spontaneous combustion of mine coal above, traditional preventiv...

Problems solved by technology

[0003] At present, the foaming device used in underground coal mines is a single passive foaming device with a low degree of automation. The gas and air intake are unstable due to the influence of underground conditions, which seriously affects the foaming efficiency, and it is impossible to independently judge and warn the location of the fire source and high temperature point in the goaf of the coal mine underground, resulting in a lag in fire extinguishing
