Joint development method - blind shaft development plan for the lower shaft

This development scheme (Fig. 7-16) is generally applicable to mines where the ore body or ore body group has a steep dip angle, the ore body has been extended deep, and the geological reserves are abundant. In addition, because of the large production capacity of shafts or blind shafts, this method is often used in medium or large mines.

The advantages of the shaft blind shaft development scheme are as follows: 1) The stone gates in the middle section of the well are not too long, especially in the initial stage of the infrastructure, so the initial capital investment can be saved and the infrastructure period can be shortened. 2) Under the condition that the deep geological data is unclear, the upper shaft is constructed; when the deep geological data is cleared and the inclination of the ore body is constant, the blind shaft can be dug, the lifting capacity of the two sections is appropriate, and the mountain can be kept for a long time. Stable production.
