【简答题】
案例分析题背景： 某矿井采用立井开拓方式，其井底车场巷道(东半部分)布置如图所示。主、副井筒与巷道连接处施工已完成。副井到底后正在进行永久装备，需6个月完成。因特殊原因，主副井贯通工程尚未开始;主井提升系统临时改装已完毕。按合同约定，图示工程要在90天内完成，其中：主副井贯通(经贯通巷)20天;主井至A点(主井绕道，含两个岔点)90天;B点至F点(含等候室)20天;F点至2岔点50天;泵房、变电所及通道(含DE段)70天;C点至l岔点50天。 主现有地面抽出式风筒一趟，排水管、供水管、动力电缆各二路，矿井属于低瓦斯矿，车场巷道、硐室围岩稳定。 问题： 1.不考虑对头掘进。试画出车场工程满足工期要求的双代号网络计划图，并指出其关键路线。 2.确定施工高峰时同时施工的工作队个数，并说明各自的掘进线路。 3.如井筒较深，请建立主、副井到底后贯通前较合理的通风系统，并指出其优缺点。
