摘要
分析了神东矿区及相邻矿区综采工作面末采顶板事故发生原因,根据神东矿区实际开采条件,提出了神东矿区综采工作面顶板管控技术。结合顶板事故发生原因,提出了神东矿区综采工作面末采顶板控制对策。末采生产管控工作中让压开采至关重要,而且必须提高工作面末采推进速度和合理控制末采采高,减小老顶周期来压期间工作面矿压显现剧烈程度。
Based on the actual mining conditions in Shendong mining area,the causes of roof accident at the end mining of fully mechanized working face were analyzed and the roof control technology of fully mechanized mining face in Shendong mining area was proposed. The research shows that the intensity of periodic weighting can be reduced by increasing mining speed and controlling mining height.
