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 the GIS fuzzy comprehensive evaluation theory, according to the parameters of the ventilation status of each roadway measured by mine. And use the coefficient of variation method to objectively and quantitatively determine the weight of each factor. Taking the West Well Ventilation System in the study area as an example, the comprehensive evaluation results show that the quality of the ventilation status of the mine is good at present, and the air volume of the ventilator and the static pressure of the fan meet the requirements. The model is applied regularly to evaluate the ventilation status of each roadway and to timely grasp the safety status and quality of ventilation in each roadway.
