30多年来,我国铀矿矿井通风降氡技术有了很大的进步和提高,改善了井下作业条件,保障了矿工的安全和健康,有力地推动了我国铀矿工业的发展。 1.通风方式和通风系统的变革铀矿建设初期,几乎全部采用压入式和集中供排风的整体通风系统。由于压入式通风的风门在使用和管理方面问题较多,导致车场或坑口漏风严重。60年代后期,新设计的矿井大多选用抽出式通风,但抽出式通风风质差,氡浓度难以控制,特别是压力分布控制不好时会导致大区域空气污染。针对上述问题,铀矿通风防护人员,经过多年实践探索,已能因地制宜地选用通风方式。目
In the past 30 years, the ventilation and radon lowering technology of uranium mine ventilation in our country has been greatly improved and improved. The underground working conditions have been improved, the safety and health of miners have been protected, and the development of uranium mining industry in our country has been vigorously promoted. 1. Ventilation and Ventilation System Reform During the initial stage of uranium construction, almost all of the ventilation system with integrated ventilation system was adopted. As the push-in-type ventilation of the door in the use and management of more problems, resulting in a serious leakage of air pit or pit. In the late 1960s, most of the newly designed mines were selected for extraction ventilation, but the extractive ventilation was poor in quality and radon concentration was difficult to control. In particular, when the pressure distribution was not well controlled, air pollution in large areas was caused. In response to the above problems, uranium mine ventilation protection personnel, after many years of practical exploration, has been able to choose the ventilation method according to local conditions.
