Problems solved by technology

However, the underground detection of coal mine gas concentration is not comprehensive enough. First of all, the number of detection devices or sensors is small, and the detection is not sufficient. Moreover, the existing gas detection equipment only plays the role of detection, and there is no definite According to the detected gas concentration value, start a new step to better ensur

Example Embodiment

[0019] For ease of description, spatially relative terms such as "upper", "lower", "left" and "right" may be used herein to describe the relationship between one element or feature shown in the figure with respect to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is turned upside down, elements described as being "under" other elements or features will be located "above" the other elements or features. Therefore, the exemplary term "lower" can encompass both upper and lower positions.

[0020] The drawings show a specific embodiment of the invention. This embodiment includes a roadway 1. A number of annular wire grooves 4 are provided at the top of the roadway 1, a temperature sensor 3 is provided on one side of the bottom end of the wire groove 4, a CO sensor 11 is provided on th...

Abstract

The invention provides a coal mine gas early warning processing system. The system includes a roadway, light sticks, a temperature sensor, a wire groove, emergency lamps, gas sensors, a wire pipe, a water pipe, an audible and visual alarm A, a spraying head, a CO sensor, a surface workbench, a solenoid valve, a high pressure water pump, a processor and display, an audible and visual alarm B and anobject rack. The system performs centralized management on monitoring and early warning, and intelligent control can be achieved; disadvantages of mis-checking, data errors, report delaying and explosion-proof measure lag manually and randomly checked by using portable gas detectors can be thoroughly changed; the safety degrees of mine production can be enhanced through all-round mine gas explosion prevention formed by a ground central total control chamber and underground detecting and monitoring alarm equipment, so that the sense of safety of downhole workers can be increased; and reserve explosion-proof capabilities can be provided through multipath redundancy explosion protection, and helpless situations and senses of fear of people on coal dust blasting caused by coal mine gas blasting can be changed.

Description

technical field [0001] The invention relates to the field of coal mine safety, in particular to a coal mine gas early warning processing system. Background technique [0002] In the mining industry, coal mine safety issues are very prominent, and accidents occur frequently, which seriously endanger the lives of miners and have a huge negative impact on the country's economic development. Gas exists in coal seams and the bottom layer of coal measures, and is the gas produced during the process of organic matter decaying to form coal. Accumulated in the upper part of the channel and below the top layer, the gas itself is not toxic, cannot provide breathing, cannot support combustion, and the concentration is too high will reduce the oxygen content in the air. When the gas concentration is mixed with air in the range of 5% to 15%, it is very easy to explode. One of the main culprits of mining accidents. [0003] Gas is a general term for underground explosive, combustible and...
