It is reported that the system is composed of servers, handsets, base stations and network equipment, which can collect and process security information in real time and truly realize the informationization of coal mine safety management. The handset looks like a mobile phone, but it is essentially different from the mobile phone. The handset can not only communicate, but also undergo professional explosion-proof treatment, and has the conditions to enter the well. In recent years, with the deepening of the national standardization of coal mine safety production, the state-owned coal mines in our region are actively exploring and implementing a number of safe, reliable, scientific and practical new technologies and new equipment. Coal mine safety information management system is a bright spot, but also a bold taste in the realization of coal mine safety management information technology. Try. "Our mine introduced this system in July last year. In the first phase, 13 handsets (mine patrol recorder) were purchased, which were inspected and used by the safety department managers. The method is very simple. As long as the inspector finds the potential security hazards at the inspection site, he enters the handset directly, and then sweeps the address card, the potential security hazards are uploaded to the information management system. The disposal of all potential safety hazards can be consulted at any time by the handset on this system, so as to realize the full supervision of coal mine safety hazards, the sharing of safety information and the closed-loop management of safety work. On the basis of last year, this year, our mine has purchased more than 60 handsets, which are planned to cover all mine safety management personnel. Introduction by the Chief of Safety Section of a Coal Mine. It is reported that the coal mine safety information management system has also initially achieved full coverage of coal mine safety management personnel, and promulgated the "Coal mine safety information system management measures", standardizing the use and management of the system from the institutional level, and promoting the construction of coal mine safety management information to a new level.
