摘　　要：主要特征是:考虑到工作面搬家、采区接替、水平延深;对每一井巷断面从投资建设开始一直到服务结束;采用通路确定最大阻力路线并处理转移问题;吸收自然分风的贡献;不用计算全部井巷;提出子阶段概念,简化计算过程;提出井巷断面优化思想的三个基本出发点;给出区分动态与静态方法的标志;对新井设计和老井改造都适用;既可预先给定总负压,也可最后确定总负压。The main characters are: first, the removal of working face, the relay of mining districts and extension of level are taken into account, second, the whole procedure is considered, third, path method is adopted to determine maximal resistance routine and deal with removal problem, Fourth, the contribution of natural air quantity-distribution is absorbed, fifth, it isn抰 necessary to calculate total roadways, sixth, the concept of sub-stage is advanced and the calculating procedure is simplified, seventh, three elementary starting points of cross-section are brought forward, eighth, the mark between dynamic methods and static methods is given, ninth, the method is fit for new shaft design and old shaft reformation, tenth, the total negative pressure can be given in advance or afterward.
