摘要(Abstract):

针对特大采空区下盘滑坡体弱结构面发育、工程地质条件差等不利条件,采用硐室爆破的方式进行崩落处理,取得了良好效果。介绍了爆破方案选择、参数设计及安全防护措施,可为类似工程的爆破施工提供参考。
Aiming at large goaf landslide body with frail structure face,poor engineering geological conditions,the chamber blasting was selected to cave it and good results was achieved.The blasting scheme selection,parameter design and safety protection measures were introduced,which provided the reference for the blasting construction of similar projects.
