1. Underground mining: deposit = mining area (square kilometers) × 10000 yuan+number of surface tunnels (units) ×5000 yuan+mining period (year) ×5000 yuan.

2. Open-pit mining: deposit = mining area (square kilometers) × 10000 yuan+number of stopes (units) ×5000 yuan+mining period (year) ×5000 yuan.

3. Combined mining (underground mining and open-pit mining): deposit = mining area (square kilometers) × 10000 yuan+number of surface tunnels (units) ×5000 yuan+number of stopes (units) × 10000 yuan+mining period (year) ×5000 yuan.

The mining area and mining period shall be calculated according to the area and fixed number of years approved by the mining license.

Determine the number of open-pit roadways and stopes: new mines shall be calculated according to the number of open-pit roadways and stopes designed in the mine development and utilization design scheme; The built mine is calculated according to the actual number of surface roadways and stopes.
