三维激光扫描技术在测绘采空区中的应用

安全生产是各大矿山企业的首要目标，而采空区的存在对矿山的生产造成了安全隐患，同时也严重影响后续的矿体开采规划。如何准确掌握采空区资料，科学地揭示井下空区的几何特性及相互的空间关系对矿山安全和生产有着非常重要的意义。然而，空区测量存在人员、设备进入难，精度差、危险高等特点；而三维激光扫描技术恰恰克服了以上困难。以焦家金矿望儿山矿区为例，详细介绍了利用三维激光扫描技术实现矿山未知采空区的轮廓边界及空间定位，从而为进行空区治理及资源回采工作打下坚实的理论基础。

Application of 3D Laser Scanning Technology in the Surveying and Mapping Goaf

Safe production is the primary goal of each mining enterprises.But the existence of goaf has caused potential safety hazard for mine production，and also seriously affected the subsequent planning of ore mining.How to accurately grasp the goaf data and scientifically reveal the geometric characterization and mutual spatial relationship is of prime importance for the mine safety and production.Nevertheless，there are many difficulties in measuring goaf，such as the personnel and equipment into difficulties，poor accuracy and high risk.But the 3D laser scanning technology can overcome them.In this paper， taking the Jiaojia gold Wangershan mine as an example，we introduces the contour boundaries and spatial orientation of unknown goaf based on 3D laser scanning technology，so as to lay a solid theoretical foundation for the goaf treatment and resource recovery.
