早在五十年代,立井作业方式只有单行作业、平行作业和三行作业(掘、砌、安同时进行)三大类。作业方式的分类很明显是按掘、砌在时间上的关系指标,并且只有这个指标。这个分类方法首先可以使我们比较准确的计算工程的施工速度和工期,是我们分类的主要目的。其次可以使我们估算施工设备,人力等需要量,便于我们作施工方案的比较。
As early as the fifties, vertical shaft operation mode was only one-way operation, parallel operation and three-line operation (excavation, puzzle, safety at the same time) three categories. The classification of work methods is obviously based on digging, laying on the time the relationship between indicators, and only this indicator. This classification method first allows us to more accurately calculate the construction speed and construction period, is the main purpose of our classification. Second, we can estimate the construction equipment, manpower and other needs, to facilitate our comparison of construction programs.
