Full-mine self-adaptive one-dimensional and three-dimensional coupled ventilation network calculation method

Abstract

The invention provides a full-mine self-adaptive one-dimensional and three-dimensional coupled ventilation network calculation method. Daily ventilation and ventilation network calculation in a catastrophe period are organically combined through a one dimensional and three-dimensional coupling mode, fine simulation of a three-dimensional space-time process of an important wind using area is completed in a self-adaptive manner according to needs, and the advantages of high one-dimensional calculation speed and accurate calculation of a three-dimensional space-time process model are fully exerted. The one-dimensional solution is completed based on a feature line algorithm; the three-dimensional space-time process simulation is completed based on a lattice Boltzmann model; and finally, data real-time exchange at the one-dimensional and three-dimensional boundary is carried out based on a consistency criterion, so that the one-dimensional and three-dimensional self-adaptive coupling of the whole mine is completed. A deep neural network solver for solving the ventilation space-time process is constructed, so that the solving efficiency is further improved. Compared with a traditional ventilation network calculation model, the method has the advantages of being more accurate and efficient in calculation and higher in ventilation network operation state reduction degree, has good expandability, and highly meets the construction requirements of intelligent ventilation.

Description

technical field [0001] The embodiments of the present application relate to the field of mine ventilation, and in particular, relate to a mine-wide self-adaptive method for solving a three-dimensional coupled ventilation network. Background technique [0002] With the rapid development of the national economy, the country's mining of coal resources has changed from the pursuit of "quantity" to the pursuit of "quality". With the development and utilization of coal resources, its mining gradually extends to the deep, and coal seams gradually enter the gas zone. The occurrence of coal resources and geological conditions have become more complicated, and problems such as geothermal and gas pressure have become more prominent, making mine disaster prevention and control more difficult. Big. At the same time, high technologies such as the Internet, big data, and space-time intelligence have brought unprecedented development opportunities for the intelligent upgrading of my countr...
