Abstract

The invention discloses a coal mine goaf gas monitoring and early warning system based on data fusion. The coal mine goaf gas monitoring and early warning system comprises a sampling unit used for obtaining sampling gas, a measuring unit used for measuring gas concentration, a control unit used for controlling the sampling unit and the measuring unit, and an early warning unit used for monitoringthe gas concentration in real time and carrying out early warning. The coal mine goaf gas monitoring and early warning method based on data fusion comprises the steps: S1, obtaining sampled gas; S2, measuring the concentration of sampled gas; S3, judging whether the concentration of the sampled gas reaches an early warning condition or not; and S4, if the early warning condition is met, carrying out corresponding early warning response operation, or otherwise, carrying out no processing. According to the invention, the laying cost of the beam pipes can be saved, the risk of monitoring result failure caused by gas leakage of the sampling pipeline and the like is reduced, monitoring and early warning of goaf gas are realized, accidents such as coal spontaneous combustion and the like can beeffectively prevented and controlled, and the informatization and intelligence level of goaf monitoring is improved.

Description

technical field [0001] The invention relates to the field of coal mine monitoring, in particular to a coal mine goaf gas monitoring and early warning system and method based on data fusion. Background technique [0002] At present, the monitoring of spontaneous combustion in goafs of coal mines mostly adopts manual sampling analysis and bundle tube negative pressure monitoring system. However, the frequency of manual sampling analysis is low, the continuity is poor, and the reliability of the monitoring results is low; while the bundle tube negative pressure monitoring system needs to lay a long bundle tube pipeline, which is difficult to maintain. Once the bundle tube leaks, the test results are not reliable. , and the operation and maintenance of the chromatographic instruments used in the system are relatively complicated, and generally require professional personnel to operate. [0003] "A gas multi-channel online monitoring system" realizes gas sampling at multiple loc...
