A mine-wide self-adaptive method for calculating a three-dimensional coupled ventilation network

Abstract

The present invention proposes an adaptive one-dimensional coupling ventilation network solution method of the whole mine, which organically combines daily ventilation with the calculation of the ventilation network in the disaster period through a three-dimensional coupling method, so as to complete the three-dimensional calculation of important wind areas on demand and adaptively. The refined simulation of space-time process fully utilizes the advantages of fast one-dimensional calculation speed and accurate three-dimensional space-time process model calculation. Among them, the one-dimensional solution is completed based on the characteristic line algorithm; the three-dimensional space-time process simulation is completed based on the lattice Boltzmann model; finally, based on the consistency criterion, the data at the one-dimensional boundary is exchanged in real time, so as to complete the whole mine-three-dimensional adaptive coupling. Construct a deep neural network solver for solving the ventilation spatiotemporal process to further improve the solving efficiency. Compared with the traditional ventilation network solution model, this method has the advantages of more accurate and efficient calculation, higher degree of restoration of the ventilation network operating state, and good scalability, which is highly suitable for 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...
