Roadway layout for inclined mining and inclined mining
Under normal circumstances, the roof is more stable, the coal quality is harder, the roof is drenched with water, or the coal seam is prone to spontaneous combustion.
When grouting is carried out in the goaf, the inclined mining shall be adopted. When the thickness of the coal seam and the inclination of the coal seam are large, the coal quality is loose.
When soft and easy flake or gas content is large, inclined mining is appropriate. For small dip or near-horizontal coal seams,
When the inlet and return air alleys are arranged in parallel and there is no special requirement for coal seam conditions, the inclined mining can be combined with the inclined mining.
In the same way, the coal mining faces are facing the direction of the main lane, and the part above the transportation lane is mined with inclination
The lower part adopts inclined mining, which is beneficial to transportation, ventilation and roadway maintenance.
