The invention discloses a mine earthquake disaster differentiation and signal reconstruction method. The mine earthquake disaster identification and signal reconstruction method comprises the following steps that an edge computing server is used for receiving mine earthquake data from distributed mine earthquake monitoring nodes in a monitoring area through a high-speed ethernet; the earthquake data is expressed as a sparse matrix; the sparse matrix is trained by multiple neural network models and disaster results are differentiated; and a mine earthquake signal is reconstructed by an improvedsparsity self-adaptive matching tracking algorithm. The mine earthquake disaster differentiation and signal reconstruction method combines the mine earthquake monitoring and inversion method with thedeep learning technology, can greatly reduce the influence of various interference in the monitoring environment, improves the accuracy of mine earthquake disaster discrimination and the original mine earthquake signal reconstruction, and enables the inversion result to be more accurate.
Description
technical field [0001] The invention relates to the field of mining seismic signal extraction and processing in underground coal mines, in particular to a mine seismic disaster discrimination and signal reconstruction method. Background technique [0002] In recent years, mining earthquake monitoring technology has become a hot topic of research by experts and scholars in many fields. Mining earthquake monitoring technology is not only an important measure to ensure safe production in mines, but also can be combined with seismology, geology, mechanics and other fields and disciplines to monitor mine pressure, surrounding rock stress, mine hydrology, mechanical vibration, etc. , so that it can be applied in many aspects such as coal and gas outburst prediction, mineral exploration, equipment maintenance, non-destructive flaw detection, etc. However, the existing mining earthquake monitoring technology is easily affected by various disturbances in the monitoring environment, ...
