It is of great significance to study the reasonable position of mining roadway under strip coal pillar for increasing the stability of mining roadway, reducing the waste of resources, and realizing the safety production of working face. Based on the research background of the working face under the strip coal pillar in Jinqiao Coal Mine of Jining, Shandong Province, through theoretical analysis, similar material simulation experiment, and numerical simulation experiment, the stress distribution law, plastic failure range, and rationality of coal pillar setting in different width sections are systematically studied. Finally, the tailentry of working face is determined at the position of 5 m from the bottom of strip coal pillar to 1308 goaf. During the mining period of 1310 working face, the peak value of side abutment pressure is at the position of 3∼4 m; beyond 25 m in front of the coal wall, the deformation of the surrounding rock on the tailentry surface is small. After entering the advanced support section, the deformation of the two sides is mainly longitudinal crack expansion and local shallow small flakes; however, the roof is complete and stable. Therefore, the selection of tailentry location and coal pillar width has played a good role. The research results of this study can provide some reference for similar mine with similar geological and production technical conditions.

岩爆矿带状煤柱下工作面合理巷道位置研究。

研究带状煤柱下采煤巷道的合理位置，对于提高采煤巷道的稳定性，减少资源浪费，实现工作面安全生产具有重要意义。根据山东省济宁市金桥煤矿带状煤柱下工作面的研究背景，通过理论分析，相似材料模拟实验和数值模拟实验，得出了应力分布规律，塑性破坏范围及合理性。系统研究了不同宽度段的煤柱设置。最后，确定工作面的尾矿进入位置是从带状煤柱底部到1308采空区5 m。在1310工作面的开采期间，侧基台压力的峰值在3〜4m的位置。在煤壁前25 m处，尾矿进入面的围岩变形很小。进入高级支撑段后，两侧变形主要为纵向裂纹扩展和局部浅小片状。但是，屋顶是完整且稳定的。因此，选择尾矿位置和煤柱宽度起到了很好的作用。该研究结果可为具有相似地质和生产技术条件的同类矿山提供参考。两侧的变形主要是纵向裂纹扩展和局部浅小片状。但是，屋顶是完整且稳定的。因此，选择尾矿位置和煤柱宽度起到了很好的作用。该研究结果可为具有相似地质和生产技术条件的同类矿山提供参考。两侧的变形主要是纵向裂纹扩展和局部浅小片状。但是，屋顶是完整且稳定的。因此，选择尾矿位置和煤柱宽度起到了很好的作用。该研究结果可为具有相似地质和生产技术条件的同类矿山提供参考。
