地表钻孔碎石充填法在三道庄多层复合空区处理的应用地表钻孔碎石充填法在三道庄多层复合空区处理的应用 摘要：河南省栾川县三道庄露天矿是地采转露采的特别矿山，历史上留下了大量地采空区, 随着露天台阶的逐步推动，大量的地下采空区严重制约着露天开采，空区处理已经随同露天生产同步进行，本文介绍了三道庄矿区在目前条件下，处理露天采场下部大量多层采空区的方法,提出了三道庄矿区多层空区地表钻孔碎石充填法处理应具备的安全参数，法律规范了空区探测、场地准备、穿孔、爆破及铲装施工规程，解决了采矿安全，残矿回收利用问题。特别是目前，我国矿产资源紧张的情况下，对于解决国内同类型矿山资源的安全，有效利用资源、及时消除安全隐患，合理开发具有参考意义。 关键词：空区；参数;露天矿；地表钻孔碎石充填法 Flank to expose inclined hole gradually applied in three village multilayer complex goaf treatment XuyingzhanghpngzhaoYangsenlin Abstrac: Luanchuan County in Henan Province three Dao Zhuang open pit mine mining is special to opencast mining，The history of a lot of goaf，With the open step step by step，A large number of underground goaf restricts the opencast mining，Goaf treatment has been accompanied by the open pit production simultaneously，This paper introduces three Zhuang mining under current conditions，Method for treatment of open pit bottom large multilayer goaf，The three Dao Zhuang mining multilayer goaf surface drilling gravel filling process should have the safety parameters，Specification of the empty area, site preparation, perforation, blasting and shovel construction rules，To solve the mining safety, recovery of residual ore utilization，Especially at present, China's mineral resources shortage，To solve the same type of domestic mineral resources security，The effective use of resources, eliminate potential safety hazards, the reasonable development has reference significance。 Key words: goaf；parameter；open pit mine；Surface drill...
