| 摘 要： | 神府东胜矿区是目前我国探明储量最大的煤田，埋藏浅、上覆厚松散沙层是神东矿区煤层的典型赋存特征。但矿井初期开采实践表明，煤层埋藏浅却不一定矿压显现缓和。以大柳塔1203综采工作面为原型开展物理相似模拟实验。研究顶板初次破断的结构形态和贯通裂缝分布规律并对实验误差进行分析。

| Abstract: | The Shenfu Dongsheng mining area is the buried, on the duplicate thick loose sand bed is its proven the biggest coal field at the present. Shallowly typical characteristic.But coal mines buried in shallow not necessarily appear to ease pressure. Picks the 1203 syntheses working surface of daliuta as the prototype development physical similarity modelling experiment, research the structure shape of the roof＇s primary breaking and the distribution rule of through crack and carries on the analysis to the experimental error. |
