Abstract

The invention provides an underground mine ventilating system and an air quantity distribution method, and aims to solve the problem of simultaneously mining and ventilating for multiple middle sections of an underground mine. The constructed mine ventilating system takes a panel as a smallest ventilating unit; a special tail gate is utilized as a panel tail gate, and a gate which does not take the main function is taken as a panel main air inlet gate which communicates with each mining sub-section gate through a panel air-return inclined drift; an air flow purifying device and a cooling and heat exchange device are arranged in the panel air inlet gate, so that inlet air flow is purified and cooled; and a mine ventilating system with a function of isolating contaminated air from fresh airis formed. In the constructed ventilating system, two panel air quantity distribution methods are disclosed, the first method refers to controlling section dimension of each air-return inclined driftin each panel to balance air quantity of each panel, and the second method refers to arranging an intelligent regulating air window in the air-return inclined drift and a disc air-return stone gate linked with the tail gate to regulate ventilation amount 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...
