摘要
通过对综放工作面含夹矸结构复杂段顶煤放出特征和放煤工艺的研究,提出选择两刀一放单轮间隔放煤方式,有利于提高煤炭回收率,降低原煤含矸率。
The paper has studied the caving characteristics and technology on the fully - mechanized caving mining working face in structural complex thick seam containing dirt band are studied. Propose with the suggestion of the fashion of two cuttings and one caving, single round interval caving is pointed are pointed. The higher recovery rate is obtained. The rock rate of raw coal is reduced.
