• The outline of the shaft project should contain a section describing its purpose and justifying selection of the shaft site .
• 在确定竖井的直径和提升高度时（后者对于急倾斜 或多层矿床尤其重要），要考虑超出第一开采阶段 以外矿体的后续开采。

• Generally speaking , it is better to overdesign the shaft in the first stage of the project life span than later to face a bottleneck , preventing an otherwise feasible increase of production or req来自百度文库iring the sinking of second shaft .
• 因此，选择一个合适的施工方式来保证凿井工期最 短和确保不间断的作业是非常重要的。

• In determining the shaft diameter and hoisting depths (the latter especially for three dimensional or multi-seam deposits) , future mining needs have to be evaluated beyond the first stage of the project .
airflow through the shaft , with corresponding
drawing and cost specifications .
• 设计概述还应该包括该竖井特点及功能；提升装置； 提升能力，直径，和井深；井筒支护类型；主要的
管道和电缆；竖井装备的数量及功能；井底水仓的
深度；通风量，相应的技术图纸和技术经济指标的 简要描述。

• Depending on the depth of the mine , shaft sinking may consume as much as 60% of the mine development time .
• 如果竖井的延深是可以预见的，那么在不影响竖井 的正常运作，不影响它为任何上中段生产水平生产 服务的情况下，竖井横截面的部分区域可以用作竖 井延深施工的空间。
