为研究深井综放采场支承压力分布特征，采用微震和应力在线监测技术对赵楼煤矿1306工作面走向煤体垂直应力进行了现场实测。研究表明：工作面推进过程可分为初采阶段、工作面“见方”阶段和正常推进阶段。工作面“见方”阶段存在初始影响范围、显著影响范围和剧烈影响范围，初采和正常推进阶段超前支承压力没有明显的剧烈上升阶段；工作面“见方”阶段超前支承压力影响范围和相对垂直应力为其他2个阶段的1.5~1.7倍；数值模拟分析与现场实测结果吻合较好。根据支承压力分布特征，确定了不同回采阶段的合理超前支护距离和解危措施。

In order to study the characteristics of the deep shaft full-mechanized caving mining abut-ment pressure distribution, field measurement focusing on vertical stress has been carried out by using microseismic and online stress monitoring system at 1306 working face in Zhaolou mine.The research shows that the process of workface extracting can be divided into three stages: initial mining stage,“square stage”and normal mining stage. Advanced abutment pressure of the“square stage”exists three parts, that is the initial affect range, significantly affect range and severe affect range. The initial and normal mining stage has no obvious rising stage. The abutment pressure affect scope and the peak stress of the“square stage”are 1.5-1.7 times higher than those of the other two stages. According to the char-acteristics of abutment pressure distribution, reasonable advance support distance and controlling meas-ures of different recovery stages were determined.
