摘要: 针对洛钼集团三道庄露天矿下部存在大量空区威胁露天采矿安全问题,通过对采空区的归类分析,对不同类型的采空区选用不同的空区处理工艺技术,比如,中深孔爆破和深孔爆破等,处理了145次,空区面积达116.3 hm2,体积达1 339.2万m3的空区,有效地解决了采矿安全问题,为矿山采空区的治理探索出了一种行之有效的新模式,使空区治理工作逐步实现了有序化、正规化、科学化。对解决国内同类型矿山资源的安全、合理开发具有重要参考意义。

Abstract: The open-pit mining safety was threatened by the large amount of mined-out area under Sandaozhuan Open Pit Mine, Luoyang Molybdenum Group.The mined-out areas were classified and analyzed and different treatment processes were used for them respectively.For example, long and medium hole explosion and long hole explosion were used for different areas for 145 times, which involved a mined-out area of 116.3hm2 and a volume of 13.392 million  m3.This technical method has effectively solved the problems in mining safety and explored a new effective way for the treatment of mined-out area, making the work into an orderly, normalized and scientific stage.It is of important reference significance to the safe and rational development of domestic mine resources of the same type.

Key words: Open mined-out area, Treatment process, Technical exploration
