罗河铁矿采空区三维激光扫描及应用分析研究

针对传统采空区探测依靠全站仪测量存在劳动强度大、测量结果不准确等问题,采用BLSS-PE矿用三维激光扫描系统对罗河铁矿45-3^#和47-3^#采空区进行了现场扫描,构建了采空区三维实体模型,并在此基础上计算了采空区体积,说明了传统统计方式存在的不足;计算了矿房的超欠挖体积,为准确量化矿房损失率和贫化率提供了基础数据;基于采空区边界进行了二步骤回采设计,说明了采空区边界对于降低矿房损失贫化的重要意义。

3D scanning and application analysis of goaf in Luohe Iron Mine

For problems such as high labor intensity and inaccurate measurement results with total station to measuring goaf in traditional way, in this paper, the BLSS-PE 3D laser scanning system was used to scan 45-3# and 47-3# in Luohe iron mine, two three-dimensional solid models of goaf were established; and based on the models, the volume of the goaf was calculated, illustrating the shortcomings of the traditional statistical methods. Additionally, the over-excavation and under-excavation volume of the mine house were calculated, providing basic data for accurately quantifying the depletion rate of mine losses. Moreover,, the two-step mining design was carried out based on the boundary of the goaf, delaring the importance of the boundary of goaf in reducing the depletion of mine damage.
