The weak link in the management of gas in local coal mines in Taiyuan City. In the past, local coal mines in Taiyuan City also adopted a number of measures in gas management monitoring. They chose to use various types of portable gas detectors, and also used / mining cap type miner's lamps. Gas alarm device 0, but due to product quality and manufacturing process problems and services can not keep up, improper use, have not continued to use, have been eliminated. At present, the optical interference gas detector is commonly used. Because the reading of this instrument is not intuitive, there are visual errors. The most important thing is that continuous monitoring cannot be realized, and it is affected by various gases, temperature and humidity. This will not play a positive role in the gas management of local coal mines in Taiyuan City. In view of the characteristics of local coal mines dotted, wide-ranging, scattered production, frequent gas accidents, shortage of funds, and low quality of the team, it is a wise choice to use a large number of gas alarm miner's lamps as the basic detection method for local mobile gas. This method is easy to operate, high in reliability, and easy to carry, and makes up for the shortage of fixed-point regional gas detection (including mine detection system, telemetry power-off instrument, etc.). It is necessary and feasible to establish and improve multiple protection networks for gas prevention and control in local coal mines. At present, the weak link of this multiple protection network lies in the prevention and control of local gas overruns. Therefore, it is of great significance to widely promote the use of gas alarm miner's lamps. The use of gas alarm miner's lamp and its superior performance The first batch of local coal mines in Taiyuan City are equipped with cadres and cadres, gunners, and underground electric power in all coal mines in the municipal coal mine, Jinyuan district, Jiancao district and Qingxu county. A fitter and a downhole repairman. Through more than one year of trials, the application of the alarm miner's lamp has played a good role in the city's gas control and has achieved remarkable results. It has unique functions and complements other safety facilities and instruments. It is an important means for coal mines to prevent major gas accidents. Its effects and effects are mainly reflected in the following aspects: a1 can make up for the shortage of inspectors. Although the mines in Taiyuan City are equipped with tile inspectors, they are also responsible for their duties. However, each mine and each class is a tile inspector. Their work areas are wide and wide, and it is impossible to take care of all the people at the same time. The location of the work. Moreover, the number of gas inspectors performing gas inspections per shift is limited. After the employees wear the alarm miner's lamp, it is equivalent to adding a pair of monitoring gas/eye 0 to everyone. Everyone has become a tile inspector, which greatly increases the coverage of the gas inspection. Filled in the gaps in the past where the inspectors missed the inspection. The inspection time after wearing the gas alarm miner's lamp has become longer, and continuous monitoring can be carried out, so that the safety and reliability of gas prevention and control work are greatly increased. B1 can make up for the shortcomings of the gas alarm power-off monitoring system. At present, the number of gas alarm de-energizers in local coal mines is limited, and the gas conditions of underground mine roadways are also limited. Furthermore, if the sensor, transmitter's hanging position, height, etc. are not appropriate, the monitoring data may not be true, objective, and reliable. Because of the large number of distribution points, the gas alarm miner's lamp can not only monitor the gas flow at the place where the gas is directly generated in the working surface, but also comprehensively reflect the gas condition. It can also make us more systematically grasp and understand each. The gas situation at the place is complementary to the monitoring system of the gas alarm power-off device, and each has its own potential. C1 because of the gas alarm miner's lamp / human-machine lock 0 function, it is conducive to strengthen the safety awareness of workers in the prevention and control of gas. Because after the gas is over-limit, the miner's lamp frequently flickers, making people unable to work, and forcibly evacuating the over-limit zone, can effectively prevent the operation after the gas exceeds the limit. In some local coal mines in Taiyuan City, sometimes due to small air volume, it is not timely after the limit is exceeded. Some employees have troubles in thinking, and their safety awareness is not strong and they are not actively evacuated. It must be supervised by the inspectors of the tile. It is even more terrible that some people actually The adventure is quite dry. Since the use of the alarm miner's lamp, the employee's self-security awareness and safety awareness have been enhanced, and it has changed/to him to withdraw 0/he has to withdraw 0.
