Goaf fire source position detection system and method based on natural potential method

Abstract

The invention discloses a goaf fire source position detection system and a goaf fire source position detection method based on a natural potential method, which relate to the field of mine fire prediction and control. The goaf fire source position detection system comprises a fire source position detection control device, a power supply and a natural potential detection device, wherein the fire source position detection control device and the natural potential detection device are respectively connected with the power supply, and the fire source position detection control device comprises a data acquisition module, a data processing module and an inversion mapping module; the natural potential detection device comprises a reference electrode and measuring electrodes, each measuring electrode is correspondingly connected with a data acquisition card, the data acquisition cards are used for temporarily storing potential signals acquired by means of the measuring electrodes, and a protection device is further arranged above each data acquisition card. The goaf fire source position detection system and the goaf fire source position detection method solve the technical problem that real-time monitoring of the spontaneous combustion area of the coal mine goaf is difficult, can determine the range and boundary of the ignition area of the goaf, provide help for control over the fire area, and further improve the fireproof effect of the coal mine goaf.

Description

technical field

[0001] The invention relates to the field of mine fire prediction and prevention, in particular to a goaf fire source location detection system and detection method based on a natural potential method. Background technique

[0002] Spontaneous fires in coal mines, coal fields, and goafs can burn a large amount of coal resources and equipment, and the fire produces a large amount of toxic and harmful gases and high-temperature smoke that endanger the lives of underground workers and pollute the environment. Coalfield fires burn about 20 million tons of coal every year, causing vegetation degradation, land degradation, water pollution, and ecological environment damage. Due to the complexity of the causes, development and influencing factors of coal spontaneous combustion, it is difficult to find the concealed fire source of coal spontaneous combustion at the initial stage, even if there are signs of spontaneous combustion or spontaneous combustion, it is diffi...
