唐山沟煤矿作为资源整合矿井，存在通风系统复杂和安全隐患多等一系列问题，通过通风阻力测定、风机性能测试和通风系统合理可靠性评价，查找原有矿井通风系统存在的问题，分析其主要原因，提出了通风系统优化改造方案。经实施后，降低了通风系统阻力，提高了矿井通风系统稳定性和抗灾能力。

As a resource integration mine, there were many problems in Tangshangou Mine such as complex ventilation system and much hidden danger. By determining the ventilation resistance and fan performance test and reasonable evaluation of mine ventilation system, the problems of original mine ventilation system were found out and analyzed, and an optimizing and transforming scheme for ventilation system was proposed. The results showed that the resistance of mine ventilation system was reduced and the stability and ability of fighting against natural calamities of mine ventilation network were improved.
