The segmentation method is applicable to the ore mining of ore and surrounding rock with a stable slope of 30° to 55° and a steep slope of >55°.

(two) advantages

(1) The use of trackless shipping equipment, flexibility in application, high mining strength.

(2) After the mining house is finished, it is allowed to return to the mining column and treat the gob immediately. This not only improves the recovery rate of ore back to the mining column, but also better handles the empty area, thus creating favorable conditions for the next section of mining.

(three) shortcomings

(1) The mining workload is large, because each section must be driven into the section transportation laneway, rock drilling roadway, pillar mining recovery chamber and cutting lane.

(2) Most of the roadways are excavated in the rock, and the ore is less produced.

With the popularization of trackless equipment in China, the segmentation method is used to mine medium and thick inclined ore bodies, which will be an effective mining method. In particular, when other conditions are better due to the angle of inclination (40° more than one degree), this method can be used when it is not suitable by other methods.
