Application Of Fire Simulation And Monitoring System In Shanxi Carlslide Coal Mine In Emergency Plan

Accompanying the rapid growth of the coal mine intelligence and automation, the probability of occurrence of mine fires increased significantly due to various reasons, including without limitation, the increase of equipment and cable-laying. After the occurrence of a mine fire, as a result of various factors including adverse environments and complex terrains, mine fire normally possesses characteristics such as strong exigency and wide influence. Lack of effective emergency measures would have serious consequences for people and property. This article relies on the statistics collected from the affiliated coal mines of the Shaanxi Coal Chemical Industry Group Co., Ltd. and, through a numerical simulation analysis in relation to the workface mine fires, studies the change of the parameters such as roadway visibility, temperature and CO concentration during the mine fire. In addition, this article develops and analyses contingency plans basing on the video surveillance and personnel location system of the mine.This article first conducts a systematical safety analysis of the mine fires, in particular, focusing on the mine fires caused by external factors. It then studies the causes of the fires basing on the fault tree methodology. It also provides a general introduction of the S1224 face of a coal mine and identifies the hazard sources. This article then provides the numerical stimulation analysis of the S1224 Face utilising PyroSim software, as follows:(1) basing on the actual situation of the S1224 Face of the mine, establishes a model on PyroSim software, sets the boundary conditions and environmental conditions and conducts a monitoring analysis of the 52 monitoring points set up on the S1224 Face.(2) simulates the visibilities and temperatures of the S1224 Face at different times after the occurrence of the fire and conducts the dynamic simulation analysis of the aforementioned statistics; conducts a quantitative analysis of the average visibilities and temperatures of each roadway and compares the data graphs at difference times with a view to analysing the flow of the flue gas.(3) conducts an analysis of the temperatures and CO concentrations of upwards and downwards tunnels which are vertically 100 m away from the fire source, and studies the variation patterns of the parameters; conducts a simulation analysis of the temperatures and CO concentrations of the upwards and downwards spots which are vertically 15 m away from the fire source.(4) conducts a simulation of the dynamic development of the fire and analyses the dynamic development graph of the flue gas generated by the fire after taking anti-wind measures; provides assistance to the studies of the developing trend of the fire and raises suggestions of various anti-fire measures.This article then studies the personnel location system and the digital video system and their significant roles in prevention and control of the fire. It further conducts an in-depth research on the disaster relief work basing on the simulation result of S1224 Face. This research is of particular importance for the establishment of fire pre-schemes and the decision-making process during the fire, as well as the determination of refuge and rescue routes.Finally, this article establishes the specific emergency rescue pre-scheme basing on the analysis of the hazard source, together with the actual situation and the technology of roadway numerical simulation analysis, this article aims to systematically improves and optimises the emergency rescue system in case of the occurrence of fire.
