根据高家堡煤矿一盘区的地质条件,在理论分析工作面侧向岩梁断裂结构力学模型的基础上,通过数值模拟方法,主要研究了工作面煤层开采厚度、工作面长度及相邻区段工作面非等长布置对侧向煤体支承压力分布特征的影响因素。研究结果表明:随着采厚的增加,侧向支承压力峰值向煤体深部移动,峰值强度降低;随着工作面长度的增加,岩梁在工作面两侧的断裂时间提前,支承压力明显影响区域增大,其影响程度随工作面长度的继续增加而减弱;相邻区段工作面非等长布置情况下,煤柱内支承压力基本呈非对称形态发展。研究结果对并掌握侧向煤体支承压力分布规律,确定合理区段煤柱宽度及顺槽掘进的合理滞后时间或滞后距离等具有重要意义。 According to the geological conditions in a plate area of ​​Gaojiapu Coal Mine, based on the theoretical analysis of mechanics model of lateral rock fracture structure on the working face, the thickness of coal mining face, length of working face and adjacent area Influence Factors of Non - equidistant Arrangement on Pressure Distribution Characteristics of Lateral Coal Body in Seam Face. The results show that with the increase of mining thickness, the peak pressure of lateral bearing pressure moves to the deep part of coal seam, and the peak strength decreases. With the increase of working face length, the fracture time of rock beam advances ahead of working face and the bearing pressure obviously affects As the area increases, the influence degree decreases with the continuous increase of the working face length. Under the non-equidistant layout of the adjacent section face, the supporting pressure in the coal pillar basically develops in an asymmetrical shape. The research results are of great significance to understand and grasp the pressure distribution law of lateral coal-bearing and determine the width of coal pillar in reasonable section and the reasonable lag time or lag distance of tunneling.
