Abstract
The statistical information processing methods used in practice do not allow to identify the type of the ongoing process by analyzing the time series of the measured parameters of the methane-air mixture in the degassing pipelines. Based on the mathematical apparatus for assessing stability due to noise processes developed by D. Allan, an approach to determining the type of stochastic process is proposed. Based on the use of the average square relative two-sample deviation (Allan variation) to assess the operation of the degassing system of the coal mine and the change in the parameters of the methane-air mixture in the pipeline during the preparation and development of excavation sections, it is shown that it is possible to identify the type of stochastic process that determines the changes in the parameters of the methane-air mixture in the degassing pipeline in the excavation sections.
