广东大宝山矿存在地下采空区,隐患较多,严重危及矿山安全生产.结合实际工程实例,提出了在采空区塌陷区内利用超前勘探孔并辅以三维激光探测仪进行安全探测,经过近一年的施工取得了一定的效果,对后续工程的顺利开展和类似工程借鉴意义.%Many gobs in Dabaoshan mine affected the safety in production. Put forward to detecting risk by exploratory hole and C-ALS in the opencast mining, achieved a good effect during a year by applying that, and provided experience for similar and subsequent projects.
