The Optimization Of Progress Control Of Shaft Engineering

The shaft engineering is the key infrastructure project in coal mining construction, it'a resilience and the investment occupy the coal mine construction generally above 60%. It's construction speed immediately influence coal mine's, and mine construction's early completion play a crucial role in later operation and maintenance, so improved the management level of shaft engineering,speedy the construction speed, shorten the construction period is a question which urgently awaits to be solved for coal mine enterprise. This paper studies the optimization of progress control of shaft engineering.The paper analysis traditional progress control's plan, the process and the application method obtains, point out that the traditional progess control has the dynamic insufficient and the teasibility shortcoming. It absorbs positively the outstanding achievement in the management discipline, and in view of the shaft engineering construction's complexity and the particularity, in the mass injection management system's PDCA management pattern, it research shaft engineering dynamic process control from P,D,C,A step by step and proposes the specific measures.The paper introduce the network-based planning techniques briefly,do not check the complex theory discussion,but unioning shaft engineering construction actual situation,related two aspects from the resources use and the work procedure to carry on the shaft engineering time optimization research discussion ,proposed the reduction time specific measures.Finally the paper in view of the Liu Hao-gou coal mine shaft engineering construction project, analyzes and optimize the Gantt chart and network diagram of its progress schedule using the PROJECT 2003 software, reduces the construction time 3.5 months, demonstrates the good effect. Explained that the dynamic progress control and the network optimization method in the shaft engineering construction is the very practical method, should promote positively.
