矿井建设项目包括井巷、土建和机电安装几百甚至几千个单位工程(以下简称工序)的连续施工,还涉及到单位与工种之间的相互配合。为此利用系统分析的方法解决大型工程的工期,采用网络协调技术,并对其全部单位工程进行时间、成本和资源的优化,从而确定整个系统完成的最晚工期,在计划的编制及实施过程中随时进行调整。依据在已有的条件下规定系统,以达到其目的的时间和能够充分实现系统要求的可能性,作为能否实现工程目的重要评价指标。 我国建井周期过长,并且概算超支很大,其原因之一是我们对所编制计划的可靠度缺乏研究,造成计划与实际脱节。当前我国管理体制正在改革,对施工单位实行招标制,所以,解决建井工期可靠度问题已提到
Mine construction projects include well construction, mechanical and electrical construction and installation of hundreds or even thousands of units of continuous construction (hereinafter referred to as the process) of the continuous construction, but also related to the interaction between units and types of work. For this purpose, the system analysis method is used to solve the construction period of large projects, the network coordination technology is adopted, and the time, cost and resources are optimized for all the unit projects so as to determine the latest construction period completed by the entire system. During the preparation and implementation of the plan In the adjustment at any time. According to the existing conditions under the system to achieve its purpose and the time to achieve the full possibility of the system requirements as an important project to achieve the purpose of evaluation. One of the reasons for this is the long period of well construction in our country and the large budget overruns. One of the reasons for this is that we lacked a study on the reliability of the prepared plans and caused the plans to be out of touch with reality. At present, our country’s management system is being reformed, and the bidding system is implemented for the construction units. Therefore, the problem of reliability of construction period has been mentioned
