Functional features:
1. With adoption of gear mechanical transmission systems, the machine is featured with high efficiency and low noise.
2. With braking function, the spindle is flexible and reliable.
3. With adoption of frequency control in electrical system, the machine controls braking using a frequency converter, so start and brake slopes can be preset for optimal winding.
4. The scope of frequency control is wide. Sped regulation is accurate and stable. The insulation level of the motor is level F.
5. Automatic winding displacement, auto-displacement inter layer trapezoid insulation.

2 When the thickness of the ore body is 8m~10m , it is advisable to use the pre-control top and the medium-deep hole for recovery;
3 When the top and bottom plates of the ore body are more regular and the thickness is more than 3m , and the conditions permit, hydraulic drilling rigs can be used;
The number of exits that should be recovered at the same time in the four panels should not exceed three . The direction of advancement of the stope should be consistent with the direction of the panel, and the lead distance between the working faces should be 10m to 15m .
1 Shallow hole room column method should be used for gently inclined ore body with thickness less than 8m ; when the thickness of ore body is greater than 3m , it should be layered and recovered;
