矿井通风系统稳定性评价指标及其权重的确定

在对通风系统进行设计或改造时,可根据矿井的开拓、开采和地质条件,拟出多个矿井通风系统方案。由于每个方案都有优缺点,这对方案的最终确定带来一定困难,所以矿井通风系统评价体系的建立十分必要。以云南省某铜矿为背景,在运用层次分析方法的基础上构建矿井通风系统的评价体系,确定矿井通风系统稳定性的一级评判指标并建立AHP结构分析模型,确定各项指标的权重,结合工程实践得出各评价指标在通风系统中的重要性顺序为:矿井通风系统环境、矿井通风安全管理、矿井通风设施状况、矿井通风经济合理性、矿井防灾减灾能力、职工素质。为矿井通风系统设计或改造升级提供科学依据。

Determination of ventilation system stability assessment indicators in underground mines and their weights

Several underground ventilation system designs will be devised according to the conditions of excavation,development and geology in the mine during the design or renovation of the system.Since every scheme has its advantages and disadvantages,the decision is difficult to make.Therefore,an assessment system of underground mine ventilation system is necessary.The paper takes one copper mine in Yunnan as the research subject,uses hierarchy a nalysis method to establish the assessment system,settles the Grade 1 assessment indexes for the system stability,sets up AHP model,and decides the weight of every index.The engineering practice ranks the importance of the assessment indexes as follows:the ventilation environment,the safety management,the construction status,the economic reason ability,the disaster resistance and prevention and the staff quality.The research can support the design or renovation of underground mine ventilation systems.
