摘　　要：阐明了空区激光探测系统(CMS)的基本构成和工作原理,分析了井下环境温度、湿度、目标反射率及探测位置等环境因素对CMS探测结果的影响,并提出了相应的解决措施;紧密结合国内各矿山的自身特点,阐述了目前CMS在我国的研究现状,分别从空区信息动态监测、露天塌陷坑探测、采场边界对比分析、顶板安全管理、采场回采贫化损失精确测定、复杂边界矿柱回采爆破设计及实测采空区稳定性数值模拟分析等主要方面对CMS的应用进行了深入研究。研究结果表明,CMS的成功应用为我国矿山空区动态监测及安全预警等相关研究开辟了一条新的有效途径。The basic principle of CMS and the method of modeling cavities using monitoring data were introduced. The impacts to CMS probing result by temperature, humidity, target reflectivity and probing location etc were analyzed and some relevant resolved measures were brought forward. The actuality study on CMS in a domestic mine is introduced. Combining the characteristic of each mine, lots of technology researches including cavities information dynamic monitor, monitoring subsidence area, stope boundary contrast analysis, the accurate measurement of stope dilution loss rate, stope roof safety management, blasting design of pillar and the stope stability numerical simulation analysis based on the monitoring cavities were carried out. It is proved that the successful application of CMS opened up a new effective way for domestic related study on cavity dynamic monitor and safety prediction.
