Abstract

The article is devoted to the problem of reducing the risk of explosions of gas-dust-air mixture in coal mines. Dust suppression means do not reduce the dust content of the air to the maximum permissible values, therefore, the dust content of the air in the workplace exceeds the permissible level at times. The results of comprehensive studies of the means of protecting workers and equipment from the danger of gas-dust-air explosions used in coal production from the simplest to the most effective and promising are presented. A methodology has been formulated to prove the effectiveness of dust pressure technologies by using generally accepted research methods. The results of comparing the possibilities of mine atmosphere protection options depending on the equipment and technology used are given. The parameters and possibilities of promising methods of preventing explosions of the gas-dust-air environment are detailed. Calculations of dust removal parameters are given. A dust suppression scheme using conical and cylindrical waterair ejectors and foam is recommended for the development of thin steeply falling layers of coal. The possibility of combining the capabilities of dust and gas protection with traditional shaft ventilation is shown.

Keywords
