摘要
为了对自走铁矿采空区进行地压监测,经过对现场的大量考察和研究,在自走铁矿布置了5个声发射和位移监测点,并分析了五个监测点的声发射数据和位移数据变化特点和规律,并得出相关结论。总结得出一整套的监测方案,为现场施工人员对采空区地压监测提供了可靠的依据,能够对地压灾害做出准确的判断。
In order to carry out ground pressure monitoring of a self-running iron ore mined-out area, five a- coustic emission and displacement monitoring points were arranged in the self-running iron ore mining area, and the characteristics and laws of the acoustic emission data and displacement data of the five monitoring points were ana- lyzed and the relevant conclusions drawn after a lot of research on the scene. A set of monitoring programs were summarized for the site construction workers on the gob pressure monitoring, providing a reliable basis for practice of ground pressure monitoring to make accurate judgments.
