The. The Summer Shops Mine Lane Works Progress Administration

Coal Mine project is under construction Pingdingshan Shenma mine, the design production capacity of 1.5×106t/a, vertical shaft development, the main shaft, auxiliary shaft, air shaft 3 shaft arrangement established in industrial sites, the shaft bottom elevation-500m to four groups of coal, two groups of coal roadway layout to form a production system, the first of 41 mining area,4101 first workface. Production around the first face, the roadway project construction and management.This paper analyzes the unit project, part project, constitute a single project, the roadway infrastructure projects WBS decomposition, including the shaft, bottom connection, chamber, level roadway, Shek Mun, coal bunker, Inclined, Mining District, Lane, a total of 35 yards, etc., and make the project queue. Draw a bar chart works, while the introduction of network planning techniques, preparation of monthly distribution of investment column, found a serious imbalance in investment in January, the proposed delay in the main shaft auxiliary shaft, air shaft 4 months construction. On the auxiliary shaft and the line was re-queue optimization, auxiliary shaft derrick equipment permanently installed after the construction vice shaft, and adjust the order of the auxiliary shaft road construction, will pump substation, water storage construction and auxiliary shaft shaft bottom,41 Transport Lane mining area -500 parallel operations. This will reduce the imbalance on the investment. Adjust the critical path of the project content, will be non-critical works as the content of parallel operations, effectively shortening the duration of the roadway project.Xiadian CoalMine and project engineering network investment plan to adjust the balance, so that the image analysis process more understandable. Optimized to shorten the duration of 7.1 months, put into operation ahead of time, can produce good economic and social benefits. The proposed project network plan to adjust the balance of project investment and construction management of underground construction has a utility, but also for coal mine construction units made from practical experience management concepts and methods, especially to protect the balance of project investment prerequisite for the progress of construction, network planning technology, optimize the schedule for providing technical assurance.
