摘　　要：基于基点气压计测量得到煤矿各用风点通风阻力,随后选择4个Ⅱ级指标、11个Ⅲ级指标构建通风系统评价体系,评价结果显示原有通风系统整体可靠。为了弱化设备可靠性和环境运行可靠性对通风系统的影响,提出延长回风大巷至井田边界的通风优化方案,优化后的通风方案可行且通风效果良好,保障了工作面的顺利回采。Based on the measurement of base point barometer,the ventilation resistance of each air point in coal mine is obtained.Then,four secondary indexes and 11 tertiary indexes are selected to construct the evaluation system of ventilation system.The evaluation results show that the original ventilation system is reliable as a whole.In order to weaken the influence of equipment reliability and environmental operation reliability on the ventilation system,the ventilation optimization scheme of extending the return airway to the boundary of the mine field is proposed.The optimized ventilation scheme is feasible and the ventilation effect is good,which ensures the smooth mining of the working face.
