Mine Fire Source Discrimination Using Fire Sensors and Neural Network Analysis
Fire experiments were conducted in the Safety Research Coal Mine (SRCM) at the National Institute for Occupational Safety and Health, Pittsburgh Research Laboratory, with coal, diesel-fuel, electricalcable, conveyor-belt, and metal-cutting fire sources to determine the response of fire sensors to productsof-combustion (POC). Metal oxide semiconductor (MOS) and smoke fire sensors demonstrated an...
متن کاملIn-mine Evaluation of Underground Fire
The current s t a t e of the a r t of f i r e and smoke detect ion technology i s reviewed from the standpoint of s u i t a b i l i t y f o r use i n underground metal and nonmetal mines. Detection modes, f i r e signatures, and environmental considerat ions a r e included. Preliminary r e s u l t s of longterm, in-mine t e s t s a r e presented.
متن کاملMultiple Type Discriminating Mine Fire Sensors
Multiple Type Discriminating Mine Fire Sensors J.C. Edwards, R.A. Franks, G.F. Friel, C.P. Lazzara, and J.J. Opferman NIOSH/Pittsburgh Research Laboratory Pittsburgh, PA 15236-0070 ABSTRACT It was determined that a selection of different types of fire sensors could be used to discriminate mine fires from nuisance emissions produced by diesel equipment. A neural network (NN) was developed for ap...
متن کاملCO dispersion from a coal fire in a mine entry
Five mine fire experiments were conducted in a 2.08 m high and 2.90 m wide, ventilated mine entry in the National Institute for Occupational Safety and Health (NIOSH)’s Safety Research Coal Mine (SRCM) to determine the effect of the dispersion of carbon monoxide (CO) on mine fire detection. CO measurements were made at distances from 7.6 m to 45.2 m downwind from the fire with diffusion mode CO...
متن کاملApplication of VENTSIM 3D and mathematical programming to optimize underground mine ventilation network: A case study
Ventilation is a vital component of an underground mining operation, used to guarantee a safe atmosphere for workers and survive them from the hazardous and toxic gases. In the recent years, engineers have begun to apply new operation research techniques in order to optimize the ventilation systems to assist in achieving a regulatory compliance, reduce ventilation costs, and improve its efficie...
