压入式通风在开采群脉型铀矿床中的优越性

简述了群脉型铀矿床地质特征和开采技术特点，结合抚州铀矿矿井下通风排氡的实践，详细论述了开采群脉型铀矿床中采用压入式通风的优越性。认为：压入式通风不仅有利于控制入风污染、减少氡气析出，从而达到用较少的风量获得较好的降氡效果的目的，而且由于在采用压入式通风时，在提升井附近增加一个井筒，从而为解决基建期井筒转入平巷施工时的通风问题和缩短建井工期创造了有利条件。此外，压入式通风便于病发区段回风，有利于多工作面同时作业，尤其适合于群脉型铀矿 床的特点。

ADVANTAGES OF PLENUM VENTILATION FOR VEIN-GROUP-TYPE URANIUM DEPOSITS

Geological characteristics and mining features of vein group type uranium deposits are presented. Combined with Fuzhou Uranium Mine, advantages of plenum ventilation for vein group type uranium deposits are described in detail. The technique can not only control intake air pollution and reduce radon eduction in order to better attenuate radon with fewer air quantity, but also solve the ventilation problem for pit shaft during construction being transfered to drift and shorten construction time. In addition, it can make air return for different sectors and simultaneous operations for some working faces.
