Problems solved by technology

[0004] In order to solve this problem, domestic coal mines mainly adopt "Y" type, "W" type, "U+L" type, and "U+I" type ventilation methods. The working face with a large amount of gushing and the risk of coal seam spontaneous combustion still cannot fundamentally solve the problem of gas exceeding the limit in the upper corner of the working face

Embodiment Construction

[0017] Such as figure 1 As shown, a ventilation system for controlling gas overrun in the upper corner of the mining working face includes: an air inlet lane 2 and a return air lane 3 arranged on both sides of the working face 1, and the first air inlet lane 2 and the return air lane There is also a second air inlet lane 4 between the lanes 3. The second wind inlet lane 4 is arranged on the side close to the return air lane 3, and the distance between the air return lane 3 and the return air lane 3 is 10-30m. The second lane 4 is arranged in parallel with the return air lane 3.

[0018] In the present invention, in the commonly used "one into one return" "U" type working face ventilation mode, the second air inlet lane 4 is added, and the commonly used "one into one return" "U" type of working face ventilation mode adopts the air inlet one lane 2 and The return air lane 3 is set on both sides of the working face 1, and the first air inlet lane 2 is connected with the panel be...

Abstract

The invention belongs to the technical field of coal mine safety, and particularly relates to a ventilating system for managing overrunning of corner gas on a recovery working face. The ventilating system for managing overrunning of the corner gas on the recovery working face is simple and reasonable in structure, and capable of effectively solving the problem of overrunning of the corner gas on the recovery working face. A first air inlet way and an air return way are arranged at two sides of the working face, and a second air inlet way is arranged between the first air inlet way and the air return way. The second air return way is arranged on a side close to the air return way and has the distance of 10cm to 30cm with the air return way, and the second air inlet way is arranged with the air return way in parallel. The ventilating system for managing overrunning of the corner gas on the recovery working face mainly solves the problem of overrunning of the corner gas on the recovery working face.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety, and in particular relates to a ventilation system for controlling excessive gas in the upper corner of a mining working face. Background technique [0002] The ventilation mode of the coal mining face is of great significance to improve the ventilation capacity of the coal mining face, prevent the accumulation of gas in the coal mining face, prevent the occurrence of ventilation gas accidents, and realize the high production and efficiency of the coal mining face. [0003] The traditional "U" type ventilation is widely used because of its simple system, less roadway maintenance, and easy management. However, with the mechanization of coal mining, the output of the working face has been greatly increased, and the amount of gas emission has also increased accordingly, resulting in serious gas accumulation in the upper corner beyond the limit, highlighting the serious drawbacks of the "U"-s...
