立井掘进是一个复杂的随机系统,为了使电子计算机模拟技术今后能广泛应用于立井施工,本文根据现场实测的大量数据,用数理统计方法,进行理论分析。得出井筒掘进作业中装岩、提升时间的分布规律及有关参数,以便为编写立井施工电算模拟程序提供真实可靠的随机变量。
Vertical shaft excavation is a complicated random system. In order to make the computer simulation technology widely applicable to the shaft construction in the future, this paper makes a theoretical analysis based on a large amount of data measured in the field and using mathematical statistics. The conclusion is drawn that the distribution law and parameters of rock loading and lifting time in wellbore excavation work can provide real and reliable random variables for the preparation of computer simulation program of shaft construction.
