| Abstract: | Based on the detailed analysis of the distribution characteristics of the residual pillars left in the first mining phase of Daguangshan Mine, an ore pillar extraction method combining caving with drawing funnel was proposed, that is, to draw the ore concentratedly by drawing funnel under the overburden strata after manual caving of the ore pillars. Analysis and assesment of the stability and production reliability of 17m thick preserved level partition pillar in the ore pillar recovery project were made. Economical assesment results have proved both social and economical benefits of this project. |
