大冶铁矿尖林山车间龙洞采区因采用无底柱分段崩落法采矿爆破后部分区域与地表贯通，出现严重的漏风现象，不仅龙洞采区通风困难，还对整个井下通风系统造成较大的影响；对此，通过对通风系统监测数据以及现状分析，以采取增加新西回风井、通风联络道和通风构筑物的方式，优化井下通风系统，有效地解决了系统通风的难题。

Jianlinshan Workshop in Daye Iron Mine is divided into three separate mining areas .However ,the separate mining areas connect to each other ,whose ventilation systems have mutual effect ,consequently forming a whole with mutual restraint and after mining blasting using non-pillar sublevel caving method ,some areas of Longdong mining area is linked up to sur-face ,causing severe air leakage .Not only Longdong mining area has ventilation difficulties ,but also the entire underground ventilation system is impacted greatly .Therefore ,with monitoring data and status analysis to the ventilation system ,it is ac-knowledged that adding new west airshaft ,ventilation linking taxiway and ventilation structure can optimize underground venti-lation system and the problems of ventilation system can be effectively solved .
