针对大倾角特厚煤层综放采场冒落矸石下滑充填及顶板破断特征,将大倾角煤层采场上覆岩层视为倾斜弹性板,利用“板”的理论对大倾角综放采场顶板矿压显现规律进行了研究。研究表明,大倾角特厚煤层综放采场顶板的破断特征与冒落矸石的下滑、充填程度有密切关系,且受矸石影响较大。根据采场顶板的不同条件对其破断特征进行了研究,得出大倾角特厚煤层综放采场矿压显现规律及顶板破断特征。
In view of the characteristics of falling gangue filling and roof breaking in the fully mechanized top coal caving mining face with steep-angle and extremely thick coal seam, the overlying strata in the stope of stope coal seam are regarded as the sloping elastic plate. The theory of “plate” The law of occurrence of roof pressure is studied. The research shows that the breaking characteristics of the roof of the fully mechanized top coal caving mining face in steeply-inclined and extremely thick coal seam is closely related to the decline and filling of the fallen gangue and is greatly influenced by the gangue. According to the different conditions of stope roof, its breaking characteristics are studied, and the law of underground pressure and roof breaking characteristics of fully mechanized caving mining face in deep inclined and extremely thick coal seam are obtained.
