基于空区探测的采场超欠挖量计算及顶板安全分析

采用空区三维激光精密探测系统（3D Cavity Monitoring System，CMS）对金属矿开采形成的采空区进行精密探测，以探测数据为基础运用大型矿床建模软件SURPAC建立与矿山实际坐标完全一致的空区三维模型。将建立的空区探测模型与采场设计单元模型复合，并通过模型间的布尔运算，计算出采场的超挖量与欠挖量。用SURPAC对实际探测获得的空区模型进行剖切，并将剖切所获得的剖面与采场施工设计剖面进行对比，分析顶板巷道工程的安全状况，从而为矿山进一步改进采场回采设计和进行安全控制提供第一手资料。

Calculation of Stope Over-Excavation and Under-Excavation and Safety Analysis for Above-Roof Openings Based on CMS Survey

CMS (3D Cavity Monitoring System) is used to make a precise survey of the cavity formed by mining in a metal mine and a 3D model for the cavity that has coordinates fully identical to those of the real mine is established based on the survey data by using SURPAC which is a large deposit modeling software. The cavity survey model established is compounded with the unit model of mining design and the stope over-excavation and under-excavation of the stope are calculated by doing Boolean operations between the models. The cavity model obtained by the real survey is dissected and the obtained sections are then compared to those of the stope construction design for analyzing the safety conditions of the above-roof opening engineering, providing first-hand data for the further improvement of the extraction design and for the safety control of the mine.
