摘要
主要阐述了放顶煤工作面顶煤破碎机理及放煤高度的合理确定;针对放顶煤工作面的顶煤厚度和煤质软硬程度,正确认定顶煤是否具有可放性,为工作面能否一次采全高提供科学依据。
The top coal broken mechanism and reasonable determination of caving coal heigh in caving coal faces are expounded. Aiming at the top coal thickness, soft and hard extent mature of coal, the feasibility of caving top coal is firmly believed, the scientific basis of mining coal overall thickness at one time is provided.
