Support-surrounding rock relationship and top-coal movement laws in large dip angle fully-mechanized caving face
When mining the fully-mechanized longwall caving face along strike, the unstable equipment, the low top-coal recovery ratio and the difficulty in controlling surrounding rock may occur due to large dip angle. Considering the effects of strike angle on support stability, the “support-surrounding rock...
