综采放顶煤采煤是近年来开采中厚煤层及厚煤层的一种较为先进的采煤技术,它具有高产、高效、经济效益好等优点。但综采放顶煤工作面由于跟底回采,顶煤就是顶板,若顶煤破碎易片、易掉,就给顶板管理带来一定的难度,为确保工作面安全生产,综放面的顶板管理显得尤为重要。下面以石
Fully mechanized top coal caving mining is a kind of more advanced coal mining technology for mining thick and thick coal seams in recent years. It has the advantages of high yield, high efficiency and good economic benefits. However, due to the fully mechanized caving coal caving face with the end of the mining, top coal is the roof, if the top coal crushing easy, easy to give roof management to bring some degree of difficulty, in order to ensure the safe production of work face, roof of the fully mechanized caving face Management is particularly important.
