摘要
文中阐述了在井下多级机站通风系统中,采场的机站常被爆破冲击波破坏;梅山铁矿为了解决这个问题,进行了无风墙机站的工业试验;试验证明,它能承受井下爆破冲击波,能满足工作面的风量要求,简化了机站形式,提高了整个通风系统运行的可靠性,并具有较好的经济效益。
In the underground ventilation system by multi-stage fan stations,the fan stations in the stopes were destroied frequently. In order to solve this problem,the industrial tests for the fan stations without ventilation wall were carried out in Meishan Iron Mine. The test results are demonstated that this ventilation facilities were able to bear the underground explosion wave,to meet air flow requirement,to simplify fan station form,to raise the reliability of whole ventilation system,and to obtain preferable economic benefits.
