漂塘矿区井下多级机站通风系统优化与实践

针对江西漂塘钨业有限公司漂塘矿区井下通风系统混乱、漏风严重、排风不畅、风量不足等问题,充分结合矿山的实际情况对矿井通风系统进行了系统的研究改造。将分区回风与多级机站相结合,建立起了以回风侧为主的井下多(三)级机站通风系统模式,改善了井下作业环境。在井下主要机站风机的装机功率增加不多的情况下(31kW),经实地测定,通风系统的总风量从改造前的50 m3/s增加到了115 m3/s左右,有效风量率从38%增加到79%。该通风系统的建立为井下安全生产提供了可靠的保障。

Optimization and Practice of Ventilation System for the Underground Multi-staged Fan Station in Piaotang Tungsten Mine

The underground ventilation system was transformed by optimizing ventilation system to solve the current problems of disorder systems, serious wind leaking, inadequate ventilation and wind volume. Three-tiered ventilation stations are arranged using each ventilation well as independent units. Under the same installed power in the optimized ventilation system, the total ventilation volume increased from 50 m3/s before transformation to 115 m3/s at present with 41 % increased effective wind volume. The transformation of ventilation system improved the underground working environment.
