摘要: 通过对草楼铁矿井下通风系统的勘查和测定,发现-170和-230 m 中段存在风流短 路,-290 m中段部分作业地点风阻过大,-350 和-410 m中段同时作业风量供需比偏低等问题。为 此,通过增设辅扇解决局部风阻过大,采取分区通风、更换调节风门和施工通风巷道的措施提高风 量供需比,并结合生产时期的通风需求对现有风机的运行频率进行调整。通过现场测试,措施实 施后达到了预期要求。

Abstract: Through the investigation and measurement of underground ventilation system in Caolou Iron Mine,it is found that there are some problems such as short circuit of air flow in the middle section of -170 m and -230 m,excessive wind resistance in some operation sites in the middle section of -290 m, and low supply and demand ratio of air flow in the middle section of -350 m and -410 m. Therefore,by adding auxiliary fans to solve the problem of excessive local wind resistance,the measures of zoning venti⁃ lation,replacing adjusting air doors and constructing ventilation roadways are taken to improve the supply and demand ratio of air volume,and the operation frequency of existing fans is adjusted according to the ventilation demand during the production period. Through on-site testing,the measures have achieved the expected requirements after implementation.
