Problems solved by technology
However, due to the shortcomings of beam tube monitoring technology and optical fiber temperature measurement technology, such as large interference, high cost, difficult installation, single index parameter, and easy misjudgment, it is difficult to meet the needs of modern intensive and conventional mine production
In addition, the comprehensive analysis ability of the coal spontaneous combustion monitoring system in the gob area of most coal enterprises on the ground monitoring terminal is not perfect. Due to the influence of the inherent coupling mechanism between the characteristic gas concentration of coal spontaneous combustion and the ambient temperature, it is difficult to achieve the purpose of dynamic monitoring and intelligent early warning

The invention relates to a visual dynamic monitoring and early warning system and method for coal spontaneous combustion in a mine goaf. The system comprises a data acquisition unit for goaf coal spontaneous combustion characteristic information, a data transmission unit, a data processing unit, an image forming unit and an intelligent early warning unit. The wireless sensor constructs a dot-matrix wireless sensor network in the goaf, collects the internal environment temperature of the goaf and dynamic information of coal spontaneous combustion characteristic gas, and establishes a real-time visual dynamic temperature field and a gas seepage field; according to the scheme, the coal spontaneous combustion danger level is judged by utilizing a coupling mechanism between various coal spontaneous combustion characteristic gases and temperatures, the false alarm rate of a single coal spontaneous combustion characteristic variable early warning method is reduced, real-time visual dynamic monitoring and intelligent early warning of goaf coal spontaneous combustion are realized, and the timeliness, reliability and early warning accuracy of goaf coal spontaneous combustion monitoring are improved.
Description
technical field [0001] The invention relates to the technical field of coal spontaneous combustion safety monitoring and prevention and control, in particular to a visual dynamic monitoring and early warning system and method for coal spontaneous combustion in a mine goaf. Background technique [0002] Coal resources are an important energy source in our country and an important support to ensure the sustained and rapid development of the national economy. Its safe mining is of great significance to the sustainable development of the national economy. The coal mining process will be accompanied by a variety of primary and secondary disasters, among which mine fires, gas combustion and explosion disasters caused by coal spontaneous combustion are the most important causes of casualties and huge economic losses in coal mines. Coal spontaneous combustion fires have the characteristics of difficulty in detection, rapid development, difficulty in fire fighting and rescue. Once i...
