When the upper geological data is clear and the ore body shape is steeply inclined, it is reasonable to use the shaft to develop in the upper part. Once the deep geological data is obtained, and the dip angle of the deep ore body is slowed down, the blind inclined well development plan can be adopted in the deep, such as Figure 7-18 shows. In this way, the first-stage project (upper shaft part) and the deep development project (the lower part of the blind inclined shaft part can be compressed to the maximum extent, shortening the construction time, and making the development plan more economically reasonable.

Strength Training Fitness Equipment
There are many types of fitness equipment for strength training, mainly including the following categories:
1. Rower: mainly used to enhance arm strength, latissimus dorsi muscle, and coordination of movements.
2. Fitness exercise machine: Provides different exercise modes and a completely zero impact experience, similar to freely switching between climbing stairs, walking, jogging, and long-distance running, and can adjust training modes to target specific muscle groups.
3. Elliptical machine: Through smooth and fluent motion trajectories and patented cross slope technology, users can exercise muscle groups in a biomechanical posture, increasing the diversity and effectiveness of exercise while reducing muscle strain.
4. Fitness bike: simulates the movement of riding a bicycle, mainly used to enhance leg strength and cardiovascular function.
5. Stepper and Tonic Wheel: Used for aerobic and abdominal training to improve cardiovascular function and reduce abdominal fat.
6. Dumbbells and kettlebells: Perform weight training to enhance muscle strength and endurance.
7. Horizontal bar: Conduct upward pull training to strengthen upper limb strength.
8. Comprehensive training equipment: such as dragon gate frames, multifunctional strength training machines, etc., providing multiple training functions, suitable for use in home and commercial gyms.
9.Lying press artifact and pull-up device: used for chest and arm strength training, suitable for home use.
