Abstract

The invention relates to a mine series ventilation identification method based on a sub-element proton method, and belongs to the technical field of mine operation. According to the sub-element proton method, virtual protons are constructed on the air return side of a working face according to roadway ventilation network flow, move along with air flow and reach ventilation network air distribution nodes, and are automatically split into a plurality of protons according to the number of air return roadways of the air distribution nodes, and the protons move along the air return roadways respectively; and so on, the protons finally reach and converge at the air return wellhead. If the virtual protons on the air return side of one working face pass through the air inlet side of the other working face, the two working faces belong to series ventilation and have major potential safety hazards; a series ventilation path between the series ventilation working faces is calculated through a traceability method; the identification method provides technical support for a coal mine to master underground roadway air flow distribution, and provides a scientific management tool and an advanced technical means for mine ventilation gas safety management and safety production.

Description

technical field [0001] The invention belongs to the technical field of mine operation, and relates to a mine series ventilation identification method based on a fractional proton method. Background technique [0002] Mine ventilation system is the guarantee of safe production in mines. Effective ventilation methods can play a key role in reducing mine temperature, diluting toxic and harmful gases, and providing fresh air flow for underground workers; wind production is an important rule for mine safety production; The working face of the mine is the key area of ​​gas emission. If the gas concentration exceeds a certain limit, it will cause gas poisoning and cause suffocation. Toxic and harmful gases are taken, and the return air area belongs to the dirty air flow, which is not suitable for operation and provides fresh air flow for other wind-requiring points. Due to the complex network structure of mine ventilation, there may be potential safety hazards of series ventilatio...
