反井钻井技术及其在铀矿通风工程中的应用

Application of raise-boring technique to ventilation engineering of a uranium mine

简述反井钻井施工技术在国内外的发展状况,论述其应用条件和优越性,介绍抚州金安铀业有限公司采用反井钻井技术施工300多m深度通风竖井的技术经济效果,并展望了推广应用的前景。

The world-wide development status, application conditions and advantages of raise-boring construction technique are briefly introduced. Two air shafts （above 300 m depth） and a air inclined shaft（84 m depth） were advanced by raise-boring technique in a mine of Fuzhou Jin＇an Uranium Corporation. These shafts form the ventilating system of the mine. Ventilation effect was obviously improved and the good economic benefits were obtained.
