综放面合理停采线位置的确定

Determination of rational stop position of fully mechanized face with top coal caving

通过实验室相似模拟试验，对综放面收尾撤架空间的顶板稳定性进行了研究。结果表明，当工作面位于周期来压期间时，会给支架回撤带来很不安全隐患；当工作面位于周期来压之后时，此时收尾撤架非常有利于顶板的管理。最后给出了一个应用实例。

Abstract In the light of analogue test in laboratory, the stability of roof of fully mechanized working face with top coal caving is studied during withdrawing support at stop line. The results, including a actual sample introduced at the end of the paper, indicate that the position of stop line has a significant influence on the safety of support withdrawing work. If working face is to be finished during periodic weighting, the stability of roof highly is poor and the roof rock is very easy to make some trouble for support withdrawing work. If working face is to be finished just after a periodic weighting, the stability of roof is good and the roof rock easy maintained and benefit to withdraw supports.
