坚硬顶板采场围岩应力场的研究

Study on stress fields around a mining area with a tight and hard roof

应用ＡＤＩＮＡ自动动态增量非线性分析有限元程序，对白腊坪矿Ｋ１３煤层采场围岩应力场进行数值模拟，并对矿井０３１８面的矿山压力显现特点进行了分析和讨论。

Abstract Numerical modeling was carried out on the stress field around a mining area in K13 seam in Bai La Ping Colliery using non-linear finite element numerical modeling soft package ADINA. An analysis and discussion on the behavior of ground pressure around No. 0318 mining area was conducted.
