摘要
针对铜坑矿空场采矿法的采场结构和地压特点,运用弹性理论和经验公式对采场的顶板厚度进行了分析研究,获得了采场跨度与顶板厚度的理论关系。并结合铜坑矿采场的工程现状,利用各种跨度计算方法,确定出了12-18m跨度下顶板的安全厚度值分别为7.83,8.77,9.73,10.64m,为铜坑矿的安全生产和采场参数优化选择提供了科学理论依据。
According to the stope structure and ground pressure characteristics of the open stope method used in Tongkeng mine,studies on the stope roof thickness were carried out by elastic theory and empirical formula.Theoretical correlation between stope span and roof thickness was obtained.In terms of engineering situation of Tongkeng mine and taking various calculating method,roof safety thickness values under different stope span of 12 to 18 m were determined as 7.83,8.77,9.73,10.64 m.The study provided theoretical basison safe production and optimization of stope parameter for Tongkeng mine.
