Introduction. The great need for mineral resources has historically led to the creation of one of the most important sectors for the development of economies - the mining industry. As the volume of mining operations increases, so does the number of accidents in the mining industry. The results presented in the article are the initial stage of a detailed study of the structure of an automated fire protection system for underground mines with a wireless interface. Targets and goals. The purpose of creating fire protection systems for mining facilities is to protect people and property from the effects of hazardous fire factors and (or) limit the consequences of exposure to hazardous fire factors. Achievement of this goal is ensured in one or more of the following ways: - installation of systems for continuous automatic (automated) control of pre-explosive concentrations of dust-air mixtures in the production zones of mining facilities using industrial atomizers; - installation of systems for continuous automatic (automated) control of pre-explosive concentrations of methane-air mixtures in the production zones of mining facilities; - arrangement of fire detection systems (installations and fire alarm systems), warning and evacuation control in case of fire; - the use of automatic and (or) autonomous fire extinguishing installations; - organization of the activities of fire departments. Methods. To build an automated fire protection system (AFS), the methods of system analysis, modeling and a formalized description of the structure of the complex of hardware AFS were used. Results and its discussion. A diagram of the structure of a complex of technical means and algorithms is proposed, and a description of the technical support of the ATPZ of the mining industry facilities is compiled. It is recommended to create the system as a three-level APPS with a hierarchical structure that implements at the lower control level the functions of the local automation of the subsystems for the control of the WOC zones of dust and explosive gases, fire alarms, automatic fire extinguishing, and at the upper level - the functions of the SHMFSB. Conclusions. Thus, the proposed new technical solutions, the structure of a complex of technical means and algorithms for the functioning of an automated fire protection system for underground mines with a wireless interface, which performs the functions of explosion, fire and emergency protection of hazardous production facilities with difficult operating conditions will significantly increase the level of industrial and fire safety of underground mine workings of mines, mines and their surface structures.
