| Abstract: | This paper is in the background of the main inclined shaft frozen construction of Huozhou Pang Pang Ta coal mine, by using ANSYS finite element software and orthogonal experiment design method, frozen key Parameters of Piecewise straight holes in Large Section Slope thick overburden with rich water were numerically simulated, distribution Law of temperature field under many rows of freezing pipes in large section slope frozen construction was studied. A technique system of vertical freezing technology suitable for large section slope through thick overburden with rich water was explored and established. |
