摘要
淮北矿业集团公司朱仙庄煤矿主采煤层8煤层是特厚、极软、易燃煤层,采用轻型支架放顶煤开采。由于煤壁片帮、漏顶严重制约了轻放单产的提高,因此对综采放顶煤工作面防片帮、漏顶技术进行了研究,实践证明煤壁浅孔动压注水等技术能够有效地防治煤壁片帮、漏顶,提高轻放工作面的单产。
Be very thick, extremely soft, inflammable, as the main layer of Zhuxianzhuang Coal Mine, use light support caving mining, coal wall slide, a serious roof leakage, which restricts the increase yield from the coal face, and therefore, stucly the technology of fully mechanized coal caving face slide, roof leakage. Practice proved that the coal wall shallow hole injection techniques to help effectively combat coal wall, roof leakage and improve the yield of light - caving.
