Feasibility Analysis of Goaf Exploration by Using Microgravity Technology

利用长方体异常模型,采用数值模拟的方式研究了采空区地表的重力异常分布特征,分析了采空区深度、宽度、厚度变化时,地表重力异常的变化趋势。随着微重力技术测量的发展,采集精度和处理精度得到提升,在现有技术条件下,结合数值模拟探讨了利用微重力变化探查采空区分布的可行性。

By using the cuboid anomaly model,numerical simulation is adopted to study the gravity anomaly distribution characteristics of the goaf surface,and the variation trend of the surface gravity anomaly when the depth,width and thickness of the goaf changes is analyzed.With the development of measurement by microgravity technology,the acquisition accuracy and processing accuracy have been improved.Under the existing technical conditions,combined with numerical simulation,the feasibility of using microgravity changes to explore the distribution of goafs is discussed.
