摘　　要：目前从《建筑物、水体、铁路及主要井巷煤柱留设与压煤开采规程》中可以查阅到适用于薄煤层及中厚煤层分层开采的"两带"高度预计经验公式,尚无综放开采条件下的相关公式可供参考。通过对国内多个综放工作面实测"两带"高度统计数据的搜集和研究,归纳出了中硬或软弱覆岩条件下综放工作面"两带"高度预计的经验公式,并进行了线性关系的显著性检验和可靠性分析,公式的适用性已在现场得到了验证。A experiment formula of ＂two zone＂ height ＂ suitable for the mining in the thin seam and medium thick seam slice could be found in the ＂ Regulations of Mining in seams under the surface buildings, water body and railway and the coal pillars left in those seams and around the mine main shaft and roadways, but there was no related formula for references under conditions of fully mechanized top coal caving mining. With the collection and study on the ＂two zone＂ heights measured in the domestic several fully mechanized top coal caving miming faces, the experiment formula of the ＂two zone＂ height in the fully mechanized top coal caving mining face under the medium hard or soft weak overburden strata was summarized, the verification on the liner relationship conducted and suitability of the formula was verified at the site.
