Prediction of risk zones during heading and actual mining in coal–rock mass is yet one of the most challenging and urgent problems in the mining industry, which has been the subject of the extensive research for many decades. This article describes a case-study of prediction and location of hazardous zone with high methane content, which imperils the safety of mining. The authors set out results of seismic sounding of coal–rock mass using portable hardware–software system Mikon-GEO with a view to detecting zones which can pose a threat to the mining safety. The seismically detected zones were additionally surveyed by boring. The use of hardware–software system Mikon-GEO in accordance with the unique procedure developed by Doctor of Geology and Mineralogy, Professor V. B. Pisetskiy allows identifying risky objects in coal–rock mass without breaking preparatory workflow. The further processing of the obtained results and a new research in the similar geological conditions can enable detection of hazardous objects from the comparison of the predictive model parameters with the actual data acquired during heading or instrumental observations. At the present time, the fact of the high-accuracy location of risk objects is proved; however, interpretation and appraisal of an object are the subject of additional investigation carried out by the mine experts and geological service personnel.

Ключевые слова Geophysical exploration, seismic method, prediction, Mikon-GEO system, methane emission, coal–rock mass.
