摘要
Abstract
Based on the slope current situation of Baorixile Open-pit Mine at the end of 2022,the article establishes a coupled seepage and stability analysis slope calculation model using finite element analysis method,uses the Morgenstern Price method to analyze the seepage effect,and conducts steady-state seepage simulation on the slope of No.1 coal water logging pit,obtaining the distribution law of steady-state seepage pore pressure.The results show that above the pressure head contour line,the pore water pressure is negative,and the negative pore water pressure value increases as it approaches the slope surface,with a top pressure of-400 kPa.The lower pore water pressure is positive,the farther away from the slope surface,the greater the positive pore water pressure value is,and the bottom is 800 kPa.The overall flow shows a central tendency trend towards the slope toe.The current slope stability system at the location of 1 coal sump at the end of 2022 meets the requirements of safety reserve coefficient.关键词
