Problems solved by technology
[0003] The main problem facing working in the underground coal mine environment is the air problem inside the underground coal mine. It is known from common sense that some toxic and flammable gases are located in deep rock formations, so tunneling and mining in this place requires air protection. The traditional monitoring method is to carry out fixed-point monitoring by manually holding the monitoring instrument, and the monitoring efficiency is low; in addition, the traditional ventilation method is to directly discharge the internal harmful gas into the atmosphere through the fan, which will cause surrounding air pollution. Environmental deterioration, resulting in environmental problems

The invention relates to the technical field of monitoring and purifying equipment, and further discloses a coal mine tunnel air monitoring and purifying device including tunnels; a fixed frame is fixedly mounted on the inner wall of the tunnel; a sliding rail is welded to the front face of the fixing frame. Rolling wheels are connected into the sliding rail in a rolling mode, the sliding rail ismovably connected with purification equipment through the rolling wheels, a gas flowing pipeline is arranged in an inner cavity of the purification equipment, first filter screens are installed at thetwo ends of the gas flowing pipeline and the side wall of the purification equipment, and a laser element analyzer is arranged in the middle of the gas flowing pipeline. The invention discloses a coal mine tunnel air monitoring and purifying device. By arranging the purification equipment capable of sliding and displacing, the purification equipment can slide in real time to follow the tunnelingprogress while coal mine tunneling is conducted, the purification equipment monitors the concentration of harmful gas underground through lasers, the purification equipment is started immediately whenthe concentration reaches an early warning value, and therefore the safety of underground work is guaranteed.
Description
technical field [0001] The invention relates to the technical field of monitoring and purification equipment, in particular to a coal mine tunnel air monitoring and purification device. Background technique [0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. Underground coal mines have deeper geological layers, so the risk factor is higher than that of open-pit coal mines. [0003] The main problem facing working in the underground coal mine environment is the air problem inside the underground coal mine. It is known from common sense that some toxic and flammable gases are located in deep rock formations, so tunneling and mining in this place requires air protection. The traditional monitoring method is to carry out fixed-point monitoring by manually holding the monitoring instrument, and the monitoring efficiency is low; in addition, the traditional vent...
