摘要：
Combined the condition of the roof with the terminal mining process under fully mechanized coal mining face, caving and the stress of the roof is analyzed. And based on the analysis a strong stratified roof support scheme was put forward in Rongtai mine, which worked successfully in the field. This technical experience not only creates a good convenience for the Fast Moving, shortens the time slope expansion to dismantling equipments at the terminal mining process, but also achieves a reduction in cost and increases efficiency at the same time. In addition, it has a strong promotional value.
