(1) The construction sequence is clear and limited. The construction sequence of the mine project is limited by the space and working surface. A part of the underground engineering content must be reached after the passage (wellbore or roadway) arrives; generally one (segment) roadway or one wellbore can only have one or two working sections.
(2) Complex environmental factors have a great impact on the schedule. The environmental and geological conditions of the mine construction are complex, and accidents are always difficult to avoid. Therefore, it is necessary to have sufficient emergency measures for complex situations. At the same time, various "unpredictable events" must be done to reduce unnecessary losses during project implementation.
(III) Characteristics of the means of progress control For mine engineering, appropriate control measures must be adopted according to specific conditions. For example, if a well working face is equipped with too many construction workers, it will not only increase the construction speed, but will also contain and interfere with each other. The result may not be as obvious as ground engineering.
(IV) Parallel construction and parallel operation In order to speed up the progress of the project, the I/C. Sometimes, in order to speed up the passage of the roadway, it is also possible to increase the penetration to the side. This method of speeding up the construction schedule is reflected in the Shiwang network diagram, which will cause the network structure to change.
(V) The importance of technical means The construction speed of a mine project is closely related to the technical solutions and technical level adopted. In recent years, the "dry well" technology has been used to ensure the construction speed is fully guaranteed, which is a typical example.
