Abstract

The invention provides an underground mine ventilation system and an air volume distribution method, which solves the problem of simultaneous mining ventilation in multiple middle sections of an underground mine. A mine ventilation system constructed by the present invention uses the panel as the minimum ventilation unit; uses the special return air passage as the panel return air passage, uses the non-main function as the main air inlet passage of the panel, and the panel The return air entry in the area is connected with each mining section entry entry through the panel area return air inclined alley; an air flow purification device and a cooling heat exchange device are installed in the panel area air intake entry entry to purify and cool the incoming air flow; Mine ventilation system with dirty air and fresh air functions. In the constructed ventilation system, the present invention proposes two methods for distributing the air volume of the panels. Method 1: By controlling the cross-sectional size of the return air inclined alley in each panel area, the air volume of each panel is balanced; Method 2: By setting an intelligent adjustment windshield in the return air stone door of the panel connecting the return air inclined alley and the return air flat alley , to adjust the ventilation volume of each panel.

Description

technical field [0001] The invention relates to an underground mine ventilation system and an air volume distribution method, in particular to an isolated panel ventilation system and an air volume distribution method for an underground mine, belonging to the technical field of mining. Background technique [0002] The underground mines of metal and non-metallic mines have the characteristics of "multiple points and wide area", especially in the underground mines of non-ferrous metals, there are more and more middle sections of simultaneous mining, and some have as many as a dozen middle sections of simultaneous mining ventilation. In the traditional ventilation process method, the simultaneous recovery and ventilation of multiple middle sections often brings the problem of fresh air and dirty air in series (mine ventilation safety issue), that is, when the upper and lower middle sections are both production middle sections, the dirty air generated by mining operations in the...
