大采高一次采全高技术在神东矿区得到了广泛的应用，辅巷多通道回撤系统使神东矿区工作面搬家效率大大提高。但大采高工作面在末采阶段贯通的过程中经常发生强烈的工作面来压，这严重影响了工作面设备回撤搬家的顺利进行。因此，对浅埋煤层大采高工作面末采阶段矿压规律的研究对神东矿区浅埋煤层大采高工作面末采阶段安全、高效地回撤搬家具有工程借鉴意义。 本文首先通过对神东矿区大柳塔煤矿52304工作面、榆家梁煤矿52106工作面、哈拉沟煤矿22526工作面这3个不同采高下的综采工作面矿压实测数据的分析，掌握了浅埋煤层大采高综采工作面末采阶段的矿压显现规律。得出工作面在贯通过程中来压后矿压显现更强烈，末采阶段工作面周期来压步距比正常开采阶段变短，来压持续长度、支架工作阻力、动载系数与正常开采阶段差异不明显。 在现场工程背景的基础上，通过建立数值模拟、物理相似模拟实验，掌握了浅埋煤层大采高综采工作面末采阶段工作面超前支承压力与回撤通道煤柱内垂直应力相互影响关系及顶板结构特征。得出当工作面距离回撤通道较远时，回撤通道煤柱应力呈“回”字形分布。当工作面接近回撤通道至贯通的过程中，回撤通道煤柱内的垂直应力普遍增大且呈不对称分布，应力峰值靠近工作面侧。在周期来压过程中老顶呈现出“斜台阶岩梁”结构的垮落形式。 最后，结合矿压理论，得出了浅埋大采高工作面末采阶段等压开采的适用条件、等压煤柱及回撤通道煤柱合理留设宽度计算方法。建立了“顶板—支架—回撤通道”的“斜台阶岩梁”力学关系模型，得出了浅埋煤层大采高综采工作面末采阶段老顶的失稳类型及支架工作阻力确定公式。

The large height mining technology has been widely used in Shendong mining area, and multi-channel withdraw roadway system makes mining face move efficiency greatly improved. While the large height mining face often occur strong mine pressure in the ending-Ming stage, moving the equipment successfully is limited severely. So there will be some engineering reference value for equipment moving safety and efficiency to research on the mine pressure and roof control of ending-mining stage in the large height mining face of shallow coal seam. Based on analyzing the field data of mine pressure in 3 different large height mining face of the 52304 mining face of Daliuta coal mine, the 52106 mining face of Yujialiang coal mine and the 22526 mining face of Halagou coal mine in Shendong mining area, this paper master the mine pressure of large height mining face of shallow coal seam in the ending-mining stage.It is concluded that the periodic weighting step in the ending-mining stage is shorter than in the normal-mining stage, and the weighting persistence length, the support resistance and the dynamic load coefficient is not obvious difference. Besides, the mine pressure in the process of close to the stop line often more stronger. In field engineering background, through establishment the numerical simulation and physical similarity simulation experiments the lead abutment with withdrawal roadway coal pillar vertical stress mutual influence relations, the roof structure and the stability of coal pillar variable characteristics of the large height mining face in shallow coal seam at ending-mining stage is obtained. It is concluded that when the working face is far away from the withdrawal roadway, the stress in the coal pillar of withdrawal roadway is distributed small in the back channel and large in the inside. When the working face is close to the withdrawal roadway, the in the coal pillar of withdrawal roadway is generally increased, and the stress peak is close to the working face. During the periodic weighting, the roof broken by the form of the " oblique step voussoir beam " structure. Finally, it concluded that the wait pressure mining applicable conditions, wait pressure coal pillar and withdrawal roadways coal pillar reasonably remain width calculation method of the large height mining face in shallow coal seam at ending-mining stage by combine with the ore pressure theory. It established the “oblique step voussoir beam” mechanical relation model of the “roof-support-withdrawal roadway” under the large height mining face in shallow coal seam at ending-mining stage, obtained the roof instability type and support resistance calculating formula.
