In the figure, 1, a system draw shaft, 2, a middle-section draw shaft, 3, a spraying dust-settling box, 4, a connecting roadway, 5, a sewage pool, 6, a water channel, 7, a water spray pipe, 8 and a steel ring wind barrel.

Detailed Description

The invention is further described with reference to the following figures and examples.

Referring to fig. 1, an embodiment of the invention comprises a system orepass 1 and a plurality of midsection orepasses 2 communicating with the system orepass 1. One side of the middle-section drop shaft 2 is provided with a connecting roadway 4. And a retaining wall is built between the middle-section orepass 2 and the connecting roadway 4, and the retaining wall is provided with a ventilation opening. And a spraying dust falling box 3 is installed in the connecting lane 4, and the ventilation opening is connected with the spraying dust falling box 3 through a steel ring air duct 8.
