[0027] The specific implementation of the method will be further described below.
[0028] Implement the above-mentioned a kind of water damage spreading method that is used for the coupling of multiple roadways under the mine at any angle provided by the present invention, it is aimed at the intricate situation of the roadways under the coal mine, first take the situation that the arbitrary angle of the two roadways of the plane is the included angle as an example, and construct the roadway coupled model. Adopt the method of dividing the roadway into blocks first, and then divide the grid, as shown in the attached figure 2 As shown, 1 and 2 in the figure are the main roadway and branch roadway.
[0029] First of all, the following two ways of dividing the grid are used for division.
[0030] (1) A unified coordinate system division method for two adjacent roadways, that is, the main roadway 1 and branch roadway 2 adopt the same coordinate system. The advantage of this met...
