主溜井垮塌三维探测及可视化分析与计算

作为地下矿山开采中最重要的矿石运输工程之一,主溜井的安全性与矿山生产速度以及周边设施安全息息相关。针对某地下大型金属矿山深部4#主溜井因倒矿冲击受损的工程实际,运用空区三维激光探测系统(CMS)和大型矿床三维软件SURPAC,实现了对溜井垮塌三维信息的准确获取及可视化分析计算,得到主溜井各段垮塌量及垮塌范围,并准确获得溜井的边界信息,其中最大垮塌宽度达到6 m,第四段溜井垮塌体积高达1 011 m3。针对主溜井垮塌产生的安全隐患提出针对性的修复措施,为主溜井垮塌分析及修复提供有益借鉴及技术支持。

3D Detection and Visual Analysis and Calculation of Mine Ore Pass Collapse

As one of the most important transportation engineering in underground mining,mine ore pass is closely related to the security of mine production speed and the surrounding facilities.For the practical engineering of the 4 mine ore pass of a large deep underground metal mine,using 3D laser system,detection of empty area(CMS)and large deposits of 3D software SURPAC,realizing the 3D information acquisition and visualization computing implementation of the collapse district of mine ore pass.3D information acquisition and visualization computing implementation,obtains the amount of the collapse,the range and the boundary information,the biggest collapse width can reach 6 m,collapse volume reach to 1 011 m3.For the security risks of the collapsed mine ore pass, proposed targeting measures,which provided useful reference and technical support for the analysis of the collapse of mine ore pass.
