Embodiment Construction

[0016] Such as figure 1 As shown, a ventilation system with "U+H" layout in underground coal mines, the structure is that the working face roadway adopts five-lane layout, three air inlets and two return air ventilation methods, specifically including double lanes arranged on one side of the working face 13 , one of which is adjacent to the working face is the belt transportation and air intake lane 8 that undertakes the tasks of coal transportation and air intake at the working face, and the other is the air intake and auxiliary transport lane that undertakes the transportation of materials, equipment, personnel and air intake at the working face 9; It also includes the three lanes set on the other side of the working face 13, from the inside to the outside are the auxiliary transport and air intake lane 7 that undertakes the air intake and auxiliary transport of the working face, and the two return air lanes that undertake the return air task of the working face Lane 3 and 2...

Abstract

The invention relates to a ventilating system arranged in U+H shape under the coal mine, in particular to a ventilating systems arranged in U+H shape under the high methane coal mine, aiming at solving the problem of the ventilating system in the process of stoping the face of the coal mine. The ventilating system comprises a stoping face. One side of the stoping face is provided with a belt conveying and air intaking way and an auxiliary conveying and air intaking way in sequence, and the other side is provided with an auxiliary conveying and air intaking way, a first air returning way and asecond air returning way in sequence. The belt conveying and air intaking way and the two auxiliary conveying and air intaking ways intake air and return air after being communicated with the first air returning way and the second air returning way through a channel arranged in front of the stoping face. Therefore, the ventilating system which is arranged in U+H shape and intakes air for three times and returns air for two times is formed.

Description

technical field [0001] The invention relates to a ventilation arrangement system used in coal mine mining, in particular to a ventilation system with "U+H" arrangement suitable for underground coal mines of high-gas mines. Background technique [0002] The ventilation system of the coal mine mining face is divided into several types of ventilation systems: one inlet and one circuit, one inlet and two circuits, two inlets and one circuit, two inlets and two circuits, and three inlets and two circuits, which are suitable for different mining conditions, roadway layout, coal mining methods, ventilation requirements of working face replacement, etc., design and selection of different ventilation systems, for high gas working faces, many problems have not been solved by the above methods: such as the effective control of gas in the upper corner, the establishment of gas drainage system in gobs, There are many disadvantages such as tense mining relationship and insufficient ventil...
