(1) Calculation of the cost of the well engineering and underground track laying project 1. According to the characteristics of mine construction, the temporary facilities fee for the well engineering and the underground track laying project is divided into the wellbore period (phase I), the roadway period (second and third periods) and the tail. The construction period varies according to the regional category. The division principle is the same as the quota for the auxiliary engineering fee.
2. The safe construction fee for the tunnel engineering and the underground track laying project is divided into two levels: high biogas mine and low biogas mine. The corresponding rate is applied according to the mine biogas level specified in the design.
(2) Calculation requirements for special drilling works, ground civil works and installation engineering
1. The calculation of enterprise management fees and profits for special drilling works, artificial earthwork and installation works are calculated at the labor rate.
2. The safe construction fee for special well drilling engineering, open pit stripping project, ground civil engineering and installation engineering is calculated, which is related to mine gas grade level, and does not consider the difference between high biogas mine and low biogas mine.
