煤矿井巷断面不仅要满足安全生产的要求，其效能指标也应尽可能优化。本文详细阐述了煤矿井下巷道从其开始掘进至服务期满为止所发生的各项费用，基于数值分析法详细探讨了各项费用与巷道断面的效能关系，从经济合理的角度确定出巷道的最优断面。该方法确定的巷道断面可不仅最大限度的提高通风巷道的利用价值，提高矿井经济效益，同时为通风系统优化提供一定的理论依据。

It is basic requirements for coal mine tunnel cross-section to meet the requirement of safety pro-duction.As the same time, the efficiency should also be as optimal as possible.The paper introduces particu-larly all cost invested to some laneway from caving to serve finished, numerical value analyse method is used to confirm the relation of all the cost with corss-section, so the furthest optimization section of laneway can be educed according to the point of economic and reasonable.It will improve farthest the value in use of laneway and increase the economy benefit of mine, and provide some theory for the optimization of ventilation system.
