针对大中型基建矿井工作量大、掘进工作面多、施工环节复杂、井下需风地点多等特点,通过对比实验研究,确定利用临时机械通风实现基建矿井通风系统的构建。综合考虑各种因素,在矿井不同的施工阶段,平衡好生产与装备之间的关系,选定了临时主要通风机的型号,并安装2台于副井附近,副井井筒内布置2道风门,形成了主井、风井进风、副井回风的机械通风系统。工程实践表明,该通风系统稳定、安全、可靠,管理方便,缩短了矿建工程周期,提高了矿井抗灾减灾能力,为其它大中型基建矿井通风系统的构建提供了借鉴和参考,具有一定的推广应用价值。
According to the large workload of large and medium-sized infrastructure mines, face excavation and more complex construction steps, underground windy places and many other characteristics through comparative experimental study to determine the use of temporary mechanical ventilation to achieve the construction of infrastructure mine ventilation system. Considering all kinds of factors synthetically, the relationship between production and equipment is balanced at different construction stages of the mine. The model of the temporary main ventilator is selected and two sets of auxiliary fans are installed near the auxiliary shaft. Two air-curtains are arranged in the auxiliary shaft. , Formed a main well, wind shaft into the wind, Vice air return mechanical ventilation system. The engineering practice shows that the ventilation system is stable, safe, reliable and easy to manage, shortens the period of mine construction and improves the capability of mine disaster prevention and mitigation, and provides reference and reference for the construction of other large and medium-sized mine ventilation systems with certain promotion Value.
