竖井建设的延续时间占矿井建设总延续时间的30～60％。为了揭示竖井建设延续时间与各种技术、组织因素的关系,全苏矿井建设组织与机械化科学研究所对50条竖井的建设工程进行了分析。所调查的箕斗井和罐笼井的平均深度为878～902米,井径7.3～8.4米;空气预热井和通风井平均深802～735米,井径7.3～6.3米。箕斗井和罐笼井的平均建设速度为7.76～8.45米/月;预热和通风井为10.2～11米/
The shaft construction of the continuation of the total mine construction time extension of 30 to 60%. In order to reveal the relationship between the duration of shaft construction and various technical and organizational factors, the construction of 50 shafts was analyzed in Quanzhou Mine Construction Organization and Mechanized Science Institute. The average depth of the bucket and cage wells investigated ranged from 878 to 902 meters with a bore diameter of 7.3 to 8.4 meters. The average depth of the air preheating and ventilation wells was 802 to 735 meters and the borehole diameter was 7.3 to 6.3 meters. The average construction speed for the bucket and cage wells was 7.76 to 8.45 m / month; the preheating and ventilation wells were 10.2 to 11 m /
