FIELD: transportation.
SUBSTANCE: invention relates to development of high inclined coal seams. Development method includes the preparation of the excavation column by conveyor and ventilation drifts, the preparation of the excavation strip by flanking and passing skates along the falling line on both sides of the strip, installation of a mounting chamber at the ventilation drift, installation of securing sections in it, mechanized layering of coal in the mining face, giving the soil every slope to the skate, forced coal transport along the face in the direction of the flank slope with the slope of the layer bed towards the near slope and towards the near slope with the bed slope of the layer towards the flank slope and the ventilation of the mining face due to general mining depression. Each support section on the side of the worked-out space is connected by flexible connections to the container, and a trough with high sides is built behind the pivot fence. Lateral gap that appears between the supports during the movement is covered by the container at the soil of the formation, at the roof – by the side of the gutter of the movable section of the support. In the part of the mining face with a slope of the soil layer towards the near slope, a lateral gap is cut between the sections of the support from the side of the nearest slope. In the part of the mining face with a slope of the layer bed towards the flanking slope, a lateral gap between the sections of the support from the side of the flank slope is blocked. In the part of the mining face in the zone of change in the angle of inclination of the soil layer, the lateral gaps between the securing sections on both sides overlap.
EFFECT: invention allows improving efficiency and safety of development.
