Therefore, in the actual construction of Guo Chen, if there is a delay in the construction period of the mine construction, a variety of technical methods can be used for effective control, which can minimize the impact on the construction period. Of course, due to a lot of delay factors, most situations may be difficult to control, and ultimately affect the total duration.

If the shaft of the wind shaft cannot be delayed in time, the connection between the main and auxiliary shafts and the wind shaft cannot be carried out as soon as possible, and the mine ventilation system cannot be formed. However, in order to carry out the construction of the bottom roadway and the main roadway, it is necessary to take relevant The technical measures may increase the cost, but can better control the construction period. If the delay time is short, consider adding a air duct in the main shaft to increase the air intake, and meet the requirements of the previous tunneling. Once the wind shaft is in the end, the mine ventilation will be formed as soon as possible. If the delay time is long, the temporary ventilation system of the main well inlet air and the auxiliary shaft return air should be considered to meet the ventilation requirements of the multi-head tunneling, and the wind tunnel should be penetrated to form the mine ventilation. Either way, it will increase the cost and affect the construction period. As long as you carefully arrange and strengthen the control, you can control the impact to a minimum.
