The article is devoted to the generalization of approaches to conducting forensic mining examinations in the investigation of explosions of gas-dust mixtures in coal mines. The practical significance of the obtained results is the use of special practical knowledge of mining and other types of forensic examinations (trasological, petrochemical, firetechnical, etc.) in the investigation of explosions of gas-dust mixtures in coal mines, which will ensure rapid, complete, and safe investigation.

A characteristic feature of explosion studies is that conclusions about reliable circumstances, causes and consequences of emergency situations can often be made with the combined use of classical mining, forensic and other expert techniques. General conclusions of mining engineering and other types of expertise (trasological, petrochemical, fire-technical, etc.) in the study of explosions make it possible to: determine the technical condition of workings, machines, mechanisms and equipment; establish reliable circumstances, causes and consequences of emergency situations; consider causal relationships between the actions of specific individuals and the requirements of regulatory legal acts on labor protection.

Key words: coal mine, accident, gas-dust mixture explosion, high-temperature flame front, toxic and harmful combustion products, emergency, investigation, air wave.
