Characteristics of construction and installation costs of mining projects

1. A complete mining project often includes mine construction engineering, ground construction engineering, and electromechanical installation engineering. The composition and charging methods of these different projects will be different.
2. To realize a mine shaft engineering project, it usually requires a relatively large amount of expenses, which is only auxiliary to the formation of the engineering entity. This part of the cost also includes the basic contents of labor costs, material costs, and construction equipment usage fees. According to past habits, this part of the cost is called the auxiliary cost of the roadway engineering.
3. The so-called well engineering auxiliary cost refers to the engineering cost of the auxiliary system such as lifting, water supply and drainage, ventilation, transportation, lighting power supply, heating, and others. That is to say: the cost of auxiliary system engineering such as the lifting of the roadway construction should also be included in the labor cost, material fee, construction equipment usage fee, etc. of the construction installation fee towel. 4. It has the same nature as the auxiliary cost of the roadway engineering, as well as the cost of special drilling works. The cost of special well-drilling works refers to the cost incurred in the construction of the wellbore project using special well-drilling methods such as freezing, large rig drilling and ground pre-grouting.
5. During the mine shaft engineering project, it also involves some expenses that are not included in the usual projects, such as mine rescue, ventilation and dustproof. In the past, there were special expenses and special classifications, which can still be referred to or used.
