Problems solved by technology

[0002] Coal mine accidents occur frequently, among which water damage accidents are the "second killer" of coal mines after gas accidents. Gas accidents are far more serious; and with the gradual increase of mining depth and the large-scale development of the next group of coal, the problem of flooding will become more prominent
Inventions and research on coal mine floods at home and abroad are mainly focused on water inrush prediction, flood disaster assessment and hydrogeological research, etc. There are few studies on the spreading trend of water flow in the narrow mine tunnel and the evolution of disaster situation after the flood occurs

Embodiment Construction

[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...

Abstract

The invention provides a water damage spreading method used for coupling of multiple roadways under a coal mine at any angle. All points of a roadway coupling boundary are subjected to coordinate transformation, the points close to the boundary are screened, and assignment and calculation of the points are completed; after each time of iteration, macroscopic density and speed physical quantity of points of a grid are obtained, and the dynamic process from water bursting to spreading ending can be displayed in a highlight mode by the adoption of a software platform developed on the basis of the GIS technology. A model which achieves coupling of two roadways at any angle is built, and models which are coupled in pairs are adopted for coupling of the roadways. The method carries out numerical modeling on coupling of the roadways, and real-time speed and positions, where burst water spreads, output according to the roadway any-angle multi-module coupling algorithm are loaded into a water damage spreading image layer and displayed in a highlight mode.

Description

technical field [0001] The invention relates to a method for simulating the spread of water damage in a coal mine, in particular to a method for realizing the spread of water damage in an arbitrary angle coupling of multiple roadways in a coal mine. Background technique [0002] Coal mine accidents occur frequently, among which water damage accidents are the "second killer" of coal mines after gas accidents. Gas accidents are far more serious; and with the gradual increase of mining depth and the large-scale development of the next group of coal, the problem of flooding will become more prominent. Domestic and foreign inventions and research on coal mine floods mainly focus on water inrush prediction, flood disaster assessment and hydrogeological research, etc. There are few studies on the spreading trend of water flow in narrow tunnels in mines and the evolution of disaster conditions after floods occur. By systematically studying the spreading law of water in tunnels ...
