采煤工艺对工作面围岩控制的影响分析

Analysis of Influence of Coal Mining Technology on Surrounding Rock Control of Working Face

针对当前无法准确掌握大采高采煤工艺工作面围岩特点,导致其无法进一步推广应用于实际生产中,通过对大采高采煤工艺和综放开采工艺下覆岩结构特征、工作面来压以及液压支架载荷的对比,为推动综放采煤工艺向大采高采煤工艺的过渡具有现实意义。

In view of the fact that it is impossible to accurately grasp the characteristics of surrounding rock in large mining height mining technology working face, which can not be further applied in actual production, through the comparison of structural characteristics of overburden rock, weighting pressure of working face and hydraulic support load between large mining height mining technology and fully mechanized caving mining technology, it has practical significance to promote the transition from fully mechanized caving mining technology to large mining height mining technology.
