What is more, it is also important groundwork of mine goaf treatment and disaster monitoring. In view of the traditional goaf triangulation model tetrahedron algorithm which is prone to cause the overlap computation problem, this paper takes the original data of three-dimensional laser system CMS acquisition as the standard criterion, and puts forward a tetrahedron cumulative sum algorithm that takes laser probe as the center point to connect all the triangulation. Thus, the accurate solution of the goaf's volumes is determined. On the basis of the goaf triangulation network model generated by self-developed products-3D modeling software of goaf detection, the traditional tetrahedron algorithm of mining goaf triangulation model is improved. First of all, the center point of tetrahedral solution is determined by the algorithm, then a tetrahedron is formed through the connection of the center point and triptychs of the triangle network model. Finally, the mining goaf's volume is calculated by summing up the tetrahedral directed volumes. Actual application shows that the improved tetrahedron algorithm of mining goaf tetrahedral volume has the advantages of high precision and wide application range., authors=LUO Zhouquan, QIN Yaguang,

articleAbstract=准确获取采空区体积是矿山实施空区周边资源安全开采的重要基础性依据,也是矿山实施空区处理及其灾变监控的重要基础性工作。针对传统采空区三角网模型四面体算法易出现重叠计算的问题,本文以采空区三维激光探测系统(CMS)获取的原始数据为依据,在自主研发的采空区三维探测建模软件生成的采空区三角网模型的基础上,改进了传统采空区三角网模型四面体算法,提出了以激光探头为中心点连接所有三角网的四面体累积求和算法,实现对采空区体积的精确求解。算法首先确定了四面体求解的中心点,通过中心点与三角网模型中的所有三角片面连接形成四面体,然后运用四面体的有向体积相加实现对采空区体积的求取。实际应用表明,改进后的采空区体积四面体算法具有精度高、适用性好等优点。,
