摘要
利用放矿管理系统模拟聚矿槽放矿高度,运用三维激光扫描仪监测地表沉降值,通过长期统计对比二者在不同剖面之间的关系,分析地表地势、地质构造以及放矿速度对地表沉降的影响,为各区域合理制定放矿速度提供数据参照,以期达到缓解地表不均匀沉降和保证地压安全的目的。
Ore drawing management system was adopted for simulating ore drawing height of ore groove,3D laser scanner was adopted for monitoring ground surface settlement value,the relation of the above mentioned two values at different profile were used to do statistic and contrast in the long term,it is analyzed the effect of surface topography,geologic structure and ore drawing speed on ground surface settlement,which provide data reference to reasonable formulating ore drawing speed in order to decrease the uneven ground surface settlement,and guarantee the ground pressure safety.
