中文摘要：
地面构造和矿严重地特别由地下的洞被威胁那些不安全或无法接近的。安全、精确的洞察觉为合理的洞评估和处理是重要的。常规洞察觉方法和他们的限制被分析。那些方法不能形成被用于指示洞处理的地下的洞的 3D 模型；并且他们在察觉的精确被地质的情形极大地总是影响。在为安全利用的金属矿的 3D 洞察觉的重要性被指出；并且 3D 洞激光察觉方法和它的原则被介绍。扫描激光系统的一辆洞汽车被建议实行在与另外的激光察觉系统作比较以后的洞 3D 察觉。四地上凿穿被选择验证扫描激光系统的洞汽车的有效性。结果证明扫描激光系统的洞汽车对地下的 3D 洞察觉很合适，特别为那些无法接近的。
英文摘要：
Ground constructions and mines are severely threatened by ones. Safe and precise cavity detection is vital for reasonable cavity underground cavities especially those unsafe or inaccessible evaluation and disposal. The conventional cavity detection methods and their limitation were analyzed. Those methods cannot form 3D model of underground cavity which is used for instructing the cavity disposal; and their precisions in detection are always greatly affected by the geological circumstance. The importance of 3D cavity detection in metal mine for safe exploitation was pointed out; and the 3D cavity laser detection method and its principle were introduced. A cavity auto scanning laser system was recommended to actualize the cavity 3D detection after comparing with the other laser detection systems. Four boreholes were chosen to verify the validity of the cavity auto scanning laser system. The results show that the cavity auto scanning laser system is very suitable for underground 3D cavity detection, especially for those inaccessible ones.
