Abstract

The invention discloses a three-dimensional dynamic visualization method of water inrush of a coal seam roof. The method includes: building a data set of a mining area; according to the data set, building a 3D geologic model of the mining area; building a roof water inrush condition comprehensive evaluation zoning graph of the mining area; based on the roof water inrush condition comprehensive evaluation zoning graph, determining prepared mining areas, main tunnels, working surfaces, and water inrush point positions of the coal seam; calculating the water level of each node of a water-bearing layer in each typical period before and after water inrush, and obtaining 3D streamlines of corresponding periods; performing three-dimensional dynamic visualization simulation of stratum fracture; and performing three-dimensional dynamic visualization simulation of a groundwater flow field. The method is firstly based on the "three-map method", groundwater simulation and scientific visualization technology are employed, three-dimensional dynamic temporal-spatial expression of the water inrush of the coal seam roof is realized, and a brand-new platform for understanding and analyzing the process of water inrush of the coal seam roof is provided.

Description

technical field [0001] The invention relates to the technical field of three-dimensional geological modeling, in particular to a three-dimensional dynamic visualization method for coal seam roof water inrush based on the "three-map method". Background technique [0002] With the gradual increase of the mining depth and the mining of the lower group of coal, there are more and more examples of roof inrush (outburst) caused by roof caving and communication with the overlying aquifer or deterioration of the production environment of the working face. The problem of coal seam roof water inrush has always been a problem. Major flood hazards for the sustainable development of the coal industry in North China-type coalfields. Mine water inrush disaster has long been one of the main disasters restricting the safe and economic mining of my country's coal industry. It is known as the "second killer" of coal mines. 65% of the country's production mines and 40% of raw coal reserves are ...
