Study On Methods Of Sealed Fire Area Assessment In Coal Mine

Spontaneous combustion of coal mine fire-prevention work is the focus of governance. When dealing with spontaneous combustion at home and abroad, Closure method is often used fire-fighting. After the formation of fire area, The need of fire in the fire zone to evaluate development, To understand the effects of various fire-fighting measures, To prevent the expansion of fire and unnecessary economic losses. Therefore, the correct analysis and evaluation of closed fire zone status, Extinguishing of the fire zone, and the unsealing of great significance.In this paper, closed fire zone on the analysis of the situation at home and abroad of various fire indicators for the application of closed fire zone analysis, The use of fire, the establishment of a comprehensive evaluation system of indicators, Through the evaluation system of the closure of a comprehensive evaluation of fire zone. In the evaluation system, Not a single indicator of the instantaneous value of the fire, nor is the change of its value over time to evaluate the status of closed fire zone. But by the value of fire indicators over time trends and all kinds of fire gases in the changing relationship between the integrated assessment of the status of closed fire zone. And the use of the evaluation system of coal -140mWl Kongji set to conduct a condition assessment of fire zone, Arrive at the closed fire zone of fire extinguishing time.Computer technology applied to the closed fire zone Evaluation Study. Based on a comprehensive evaluation system, using VB and ACCESS software development, Analysis and Evaluation System, So that the evaluation process to achieve the software-based, reducing the workload of the evaluation.Figure [39] table [1] reference [74]...
