摘要
针对地下金属矿山溜井垮塌问题频繁发生,探测手段较难满足后期治理工作要求的现状,本文采用BLSS-PE空区探测系统对三山岛金矿2#溜井开展了现场探测工作,得到了垮塌后溜井三维点云原始数据,建立了2#溜井垮塌前后复合模型,确定了垮塌溜井的三维空间位置,垮塌区域实际边界,垮塌区域发展趋势;计算了不同高程垮塌面面积以及垮塌体总体积;分析了垮塌区域对于相邻工程的影响情况,为后期矿山开展溜井修复治理工作提供了数据支持。
In view of the frequent occurrences of ore-pass slipped in the underground metal mines as well as the detection methods are difficult to meet the requirement of post-treatment work,in this paper,we have carried out field exploration on 2#ore-pass in Sanshandao gold mine with BLSS-PE cavity detection system,in this way,the initial 3 Dpoint cloud data of slipped ore-pass is obtained,on this basis,the composite model is established of 2#orepass including designed and slipped ore-pass,and then the three-dimensional space and actual boundary are determined,in addition,the development trend of the slipped area is conjectured.The surface area of different elevations and the total volume of the slipped ore-pass are calculated,in the end,the influence on adjacent works is analyzed caused by the slipped area,through the discusses above,it would provide data support for the recovery and treatment of the slipped ore-pass in the later time.
