Jashchenko I. The rising of effectiveness functioning system of against-accidents defence of coal mines

Research objekt: processes of flowing and liquidation of failures in a mine ventilation system, which result in possible violation of implementation of measures, foreseen the plan of liquidation of failures, as a result of imperfection of the projected system of against-accident safety. The purpose of work is development of methods of increase of the effectivity functioning of the systems of against-accident defence of coal mines in the conditions of origin of exogenous fire, that allows to minimize duration of evacuation of people. The complex method of researches is in-process used, which contains: an analysis and generalization of scientific and technical achievements is in industry of development of methods of estimation of efficiency of acceptance of against-accident measures in an initial period of flowing of failure; imitation modelling processes of functioning of the systems of against-accident defence in emergency terms; approbation of job performances in the conditions of operating mines. On the basis of established regularities changes of prognosis time of discovering of exogen fire with due regard for non-evident duplication detectors of fire and completeness discovering of its hearts in a limits of accident part the method estimation of effectiveness of existing basis means of discjvering of origin of exogen fire was devistd. On the basis of established regularities duration of evacuation of people with the calculation of ergonomic of route, recurrence of action and capacity means of evacuation method construction routes of accident evacuation of miners from repair and threatened areas of mine was devised. The criterion of estimation of effectiveness of system against-accident defence was proposed. This criterion realize it's rise at the expense of: verification of effectiveness and perfection of proces discovering heart of origin fire and, as corollary - more well-founded notification of mine controller about place and time beginning of fire and operative limitation zones of aerate of mine ventilation network by prolucts of combustion; verification of correctness realization of accident evacuation of miners. Effectiveness of receipting results consist in diminution expenditures for the realization measures of plan liquidation of accidtnts, improvement conditions of use means of against-accident defence for the determination of it's primary tasks. Results of investigations were used in the time of working out and introduction on mines of coal branch recommendations for perfection systems against-accident defence and were included in a section of normative document.
