To the question of ventilation of underground mine workings during operation of diesel-hydraulic locomotives

The issue of organizing mechanized delivery of people and loads to underground workings is one of the key issues in mining operations. In most cases, diesel-hydraulic locomotives (DHL) are used for this purpose. The duration of downtime and output capacity of the enterprise depends on the distance from their route to the face. To ensure the safe operation of vehicles with a diesel engine in Russia, there are a number of regulatory documents (industrial safety rules, instructions, guidelines, GOSTs), which prescribe the need to control nitrogen and carbon oxides emitted with exhaust gases in the mine atmosphere, and to supply air in volume, sufficient to dilute the actual concentrations of these substances to acceptable values. In addition, RD 05—312—99 has not been canceled to date, which contains a requirement to ensure an air flow of 5 m3/min. for one hp used diesel engines. The implementation of this requirement is associated with certain difficulties and costs, in some cases it is impractical or impossible. In order to assess the validity of these requirements for the ventilation of mine workings in relation to the operation of modern diesel-hydraulic transport, an analysis of approaches to the regulation and normalization of mine atmosphere parameters used in domestic and foreign practice was performed. The volumes of DHL, their workload and traffic routes in the mines of JSC «SUEK-Kuzbass» are presented. The workings in which diesel locomotives are not currently operated due to the air consumption factor are analyzed. Ways of solving the problem are proposed.
