铁矿区采空区勘测及其危害评价研究

Study on the Iron Ore Gob Surveying and its Risk Assessment

本文采用野外勘测、理论分析和定量计算相结合的技术路线,研究了采空区分布及参数的高密度电法勘测方法、采空区对地表的影响程度和地表移动区的范围的定性定量评价方法,研究结果可以作为政府进行矿区安全生产综合整治和安全规划的科学决策依据。

In this paper , using field surveying , theoretical analysis and quantitative estimation , iron ore gob distibution and its electrical surveying were discussed , and the quantitative and qualitative evaluation methods were adopted to assess the gob risk to ground surface .The results can provide a scientific basis for the governmental decision-making when taking measures about mine district safety precautions .
