Mamayev V. Estimation scientific fundamentals development of the coal mines fire hazard

The thesis is devoted to solving the actual scientific-technical problem that consists of the working-out of fire hazard estimation highly informative methods of coal mines. The idea of the work consists of influence conformities use of origin probability of the combustible environment ignition sources, self-rescue possibility of the mine workers, as well as the fire protection efficiency on the fire safety level of an underground object and in the scientific substantiation of achievement methods of the permissible fire safety level of this object on the basis given. Such approach to solving the problem gives an opportunity to estimate the fire safety level with respect to the normalized one, and, if necessary, to work out additional measures for its achievement. To determine such level it is proposed to consider the individual risk as probability of events population of fire origin, presence end evacuation of the mine workers from the accidental district, actuation efficiency of fire protection. Determination methods of underground objects fire hazard, mining equipment, operating fluids for hydraulic drives are worked out, and heat power of the ignition source by mine conveyor belts certification tests and fire propagation length on their surface are substantiated. The scientific foundations and algorithms of functioning the prognosis automated system, of the fire hazard parameters check of the objects and of automatic fire-fighting installations control are worked out.
