摘要
基于GIS模糊综合评价理论,根据矿井实测的各个巷道的通风状态因素参数。并运用变异系数法客观定量地确定了每个评判因素的权重。以研究区西井通风系统为例,综合评价结果目前矿井通风状态质量为好,且通风机风量、风机静压均满足需求。定时应用该模型对各个巷道的通风状态进行评价,及时掌握各个巷道的通风安全状态及质量。
Based on GIS fuzzy comprehensive evaluation theory,according to the all measured the ventilation state parameters,the paper objectively determines each of the weights of evaluation factors by using variation coefficient method.Taking the west well ventilation system as an example,the comprehensive evaluation results of current mine ventilation state is good;the fan air volume,static fan can meet the demand.The model is applied to evaluate ventilation condition of each tunnel ventilation state,and grasping the safety status of each tunnel ventilation and quality.
