The horizontal section top coal caving in steep seam is different from the gently inclined seam.

急斜煤層水平分段放頂煤開(kāi)采與緩斜煤層不同,工作面沿煤層厚度的水平線布置,長(zhǎng)度短。

It mostly study on the content of the relationship between support and surrounding rock in longwall top-coal caving mining of steep seam by using field observation, theory calculation, similar and numerical simulation.
