井下采矿作业环境质量模糊综合评判

在全面分析井下作业环境质量影响因素的基础上,运用模糊数学中的综合评判法,建立井下作业环境质量评价模式。依据相关法规并借鉴成功经验和研究成果,将环境质量分为5个级别,并建立了相应的隶属函数。以程潮铁矿东区-290m水平作业场所为实例,对其采场作业环境的质量进行了模糊综合评判,指出了作业环境质量较差的主要原因,提出了相应的改进措施。实际应用表明,井下采矿作业环境质量模糊综合评判法具有较高的应用价值。

Fuzzy Comprehensive Evaluation of Working Environmental Quality under Mines

On the basis of fully analyzing the factors influencing the working environmental quality under mines,a mathematical model for evaluating the working environmental quality under mines was set up by use of comprehensive judgment method in fuzzy mathematics.The environmental quality was divided into 5 classes,and corresponding membership functions were derived.As an example,the working environmental quality at 290 m under Chengchao Iron Mine was evaluated with this method.Main causes resulting in worse environment quality were pointed out,and relevant improving measures were put forward.It proves that using fuzzy comprehensive method to evaluate the working environmental quality under mines is practical and effective.
