【摘要】 煤矿井下作业环境对煤矿安全有着重要的影响,文章运用属性层次分析法确定井下作业环境的瓦斯体积分数、粉尘、温度、湿度、风速、有害气体、噪音、作业空间等8个因素指标权重,建立了基于未确知理论的井下作业环境综合评价模型。结合山西某煤矿的具体实际,在面向对象的程序设计语言VC++6.0和数据库SQLserver2000环境下,运用ProEssentials图形组件实现了瓦斯体积分数曲线和井下作业环境综合评价曲线的显示,其应用前景良好。更多还原

【Abstract】 Working environment under mines plays an important role in safety of coal mines. The paper analyzes the eight influence factors of working environment under mines: 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 picture and Evaluation curve with the help of ProEssentials.And it will have good potential of application in the future.更多还原
