摘　　要：弓长岭铁矿因前期大量无序的开采,形成许多无规则、复杂的采空区,给日常生产留下了安全隐患。通过三维扫描探测技术,准确掌握了采空区的分布及空间形态,并提出采空区爆破处理的方案。以163第一层空区处理为实例,从爆破参数、起爆方式、起爆网路以及施工安全等方面加以考虑,对采空区进行了处理,取得了良好的效果,为以后同类型矿山采空区的处理提供一定的参考。Gongchangling iron mine disorder due to a large number of pre-exploitation,the formation of many irregular,complex gob,to daily production left a security risk.By three-dimensional scanning probe techniques,accurately grasp the spatial distribution and morphology of the mined area,and propose solutions Gob blasting process.The first layer combined 163 out area as an example,be considered from blasting parameters,initiation methods,initiation network and construction safety,etc.,on the mined-out area were processed and achieved good results for the future of the same type goaf treatment zone to provide a reference.
