Comprehensive Evaluation of Working Environment under Mining Based on Unascertained Analytic Hierarchical Model

Working environment under mining plays an important role in safety of coal mines. The paper analyzes the eight factors of working environment under mining: gas density, dust, temperature, humidity level, air velocity, and harmful air, noise, and working space, calculates the weight of factors and establishes the comprehensive evaluation model with analytic hierarchical model based on unascertained measure. This paper develops the module by the use of VC++6.0 and SQL Server2000 which can display the gas density curve and Evaluation curve with the help of ProEssentials. This method has been proved usable and reasonable by using the example. And there will be a promising future in its application.
