Which method is used in mining design of gold mines?

1. Horizontal mining: the mining direction of tailings is basically parallel to the axis of the main dam of tailings dam, and it is mined in strips along the tailings pond during sand mining. This method is divided into single-sided transverse method and adjacent transverse method.

2. Vertical mining: the direction of tailings mining is basically vertical to the axis of the main dam of the tailings dam, and sand mining is carried out in strips along the longitudinal direction of the tailings dam. It can be divided into single-sided longitudinal method and plane longitudinal method.

3. Combined mining: When the storage conditions of tailings in the tailings pond are complicated, the above methods can be combined.

Mining sequence

1. The basic sequence of tailings mining is: from the inside to the outside, from the reservoir to the dam, from the top to the bottom, and mining by layers.

2. The general direction of tailings mining is divided into backward order and forward order.

Reverse order: the overall sequence direction of tailings mining is vertical mining from inside to outside the warehouse.

Forward sequence: the overall sequence direction of tailings mining is longitudinal mining from outside the warehouse to inside the warehouse. This mining sequence should leave enough dry beach length and beach slope.

After you come back, you should clean up enough flood storage according to the design to ensure smooth drainage, so as to carry out the mining operation of dry beach and tailings dam.
