摘要
随着大红山铁矿开采深度的不断下降,无底柱分段崩落法开采后形成的地表塌陷区范围逐步扩大。为解决塌陷区带来的一系列不良影响和问题,在前期充分研究掌握矿山塌陷坑及岩移发展规律的基础上,通过系统研究,最终采用废石回填方式治理塌陷区,提出了单台阶堆排废石回填技术方案,并进行地表生态恢复,方案科学合理、可操作性强,为其他矿山塌陷区治理工程提供了借鉴。
With the falling of the mining depth of Dahongshan iron mine,the surface subsidence scope formed by non-pillar sublevel caving mining method is expanded gradually.In order to solve the adverse effects and problems caused by subsidence areas,based on researching the development regulari-ties of the mine subsidence areas and rock movement,the waste rocks backfilling method is adopted to deal with the subsidence areas by systematically analysis,the waste rocks backfilling technical scheme by single step stacked is proposed,and the surface ecological environment is restored.On the whole,the scheme proposed in this paper has the characteristics of scientific,reasonable and operability.Besides that,it also has reference for the other mine subsidence areas treatment engineering.
