摘要
新疆屯宝煤矿1154工作面,若借助经验公式推算确定"三带"高度误差较大;若采用现场实测,则成本高、周期长,难以做到提前预判。采用相似材料模拟试验,定性分析采动影响下覆岩来压规律,并对上覆岩层形成的"三带"范围进行划分,实践证明,这是一种有效的途径。
At 1154 working face of Xinjiang Tunbao coal mine, if using empirical formula determines the ＂three zones＂ height, the error is large; if using field measurement, the cost is high, the cycle is long, and it＇s hard to predict in advance. Useing empirical formula determines the height of ＂three zones＂, qualitatively analyzes the pressure regularity of overlying strata under the influence of mining, and divides the overlying rock formation of the ＂three zones＂, practice has proved that this is an effective way.
