- Annotation: It is shown that improving the safety of miner’s suits is associated with the development of theoretical concepts of physical processes in textile materials. The current understanding of the passage of dusty air through a textile material does not always ensure the safety of miner’s suits. It has been established that one of the ways to solve this problem is to build and use digital twins of the dust permeability processes of textile materials. The mechanisms of dusty air passage through a textile material are analysed, a model of dust movement in the air flow in the immediate vicinity and structure of the textile material is proposed. A mathematical model of dust particle capture by structural elements of the fabric is compiled. Based on these ideas, a numerical model of the dust permeability of a textile material is compiled, its solution is obtained using the example of fabric, an example of using the modelling results in calculating the dust permeability and dust capacity of textile materials is shown. Key words: miner’s suit, dust permeability, dust capacity, dust particles, numerical model, dust fraction, mechanisms of dust capture by material.
