ventilation device for mining

Abstract

The invention discloses a ventilation device for mining, which comprises a ventilation steel pipe, a support frame, a ventilation hose, a protection frame, a ventilation branch pipe and a fan; the ventilation steel pipe runs through the mine, and a plurality of through holes are opened on the ventilation steel pipe; the support frame There are multiple support frames arranged at intervals in the ventilation steel pipe and fixedly connected with the inner wall; the ventilation hose is parallel set inside the ventilation steel pipe, and the ventilation hose is fixedly connected with the support frame; the protective frame is fixedly connected with the through hole; the ventilation branch pipe One end is fixedly connected with the protection frame, and the other end is communicated with the ventilation hose; the ventilator is arranged outside the mine and communicated with the end of the ventilation hose. In the present invention, a ventilating steel pipe is fixedly connected to one side of the ventilator, and a ventilating hose is fixedly connected to the interior of the ventilating steel pipe through a support frame. Under this condition, the interior of the mine will not create an oxygen-deficient environment, and further improve the rescue efficiency of miners.

Description

technical field [0001] The invention relates to the technical field of mine rescue ventilation equipment, in particular to a mining ventilation device. Background technique [0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form the underground coal mine production system. Sometimes the inclined shafts, shafts, and adits in the underground development of mines are also called mines, but with the mining of mines , Mining accidents are prone to occur, and miners will be buried inside the mine, waiting for the rescue of rescuers. However, after the mine disaster occurred, the mine collapsed and the air was not circulated. The existing technology cannot supply air to the inside of the collapsed mine, which may easily cause the lack of oxygen inside the mine, and further create an unfavorable living environment for the miners buried under the mine. Greatly detrimental to the survival of miners. Moreover, after the mine ac...

Problems solved by technology

However, after the mine disaster occurred, the mine collapsed and the air was not circulated. The existing technology cannot supply air to the inside of the collapsed mine, which may easily cause the lack of oxygen inside the mine, and further create an unfavorable living environment for the miners buried under the mine. Greatly detrimental to the survival of miners

Moreover, after the mine accident, outside personnel cannot communicate with the personnel inside the mine, cannot understand the situation of the miners in distress, and cannot accurately know the location of the mining tool body, which makes rescue more difficult, which is not conducive to the rescue of miners.
