All mines must immediately install and improve equipment for emergency notification – mining, mining machinery – Machinery Industry
The total coal line controlsafety 2007 167 Supervision of the National Security Administration
National Coal Mine Safety Supervision Bureau immediately installed on all underground and improve communications, air pressure, dust water supply emergency notification system
The coal-producing provinces and autonomous regions, municipalities and Xinjiang Production and Construction Corps coal mine safety supervision and management departments and the coal industry, the provincial coal mine safety watchdog, the Ministry of Justice directly under the Coal Authority, the Shenhua Group Corporation, China Coal Energy Group Corporation : Shan County, Sanmenxia City, Henan Province branch
built mine, "7.29" incident submergence rescue to be successful, there is a significant factor was that the coal mine installed and running with communications, wind and dust pressure water supply system (hereinafter referred to "Three Lines"), provided for the trapped miners communications, ventilation and oxygen, a necessary condition for liquid food delivery.
To further enhance the level of mine safety management and to promote safety in coal mines, and after a disaster in response to the incident to create the conditions for rescue and relief work, according to "Coal Mine Safety Regulations" and "the basic conditions for coal mine safety regulations" and other relevant provisions of the Management of combining various types of coal are to be immediately installed on all the coal mines and improve mine "Three Lines" urgent notice on matters related to the following:
One to fully understand the installation of "Three Lines" importance. Mine "three lines" is the coal mine production scheduling, safety, dust removal of important facilities and effective prevention of coal and gas outburst accident, coal dust explosion is an important measure to improve coal mine disaster prevention ability to withstand major accidents facilities, normal production of "security line" trapped miners "lifeline." Management of local coal industry, coal mine safety supervision departments and the local coal mine safety watchdog, the coal mining enterprises must raise awareness, strengthen the leadership, responsibility and take effective measures, in accordance with the installation of "three line."
Second, you must install underground communication system. The main shaft mine shaft bottom, transportation dispatch room, transformer substation, the park winch room, pump house, belt centralized control of major mechanical and electrical equipment Chamber of Chamber and mining face; "year disaster prevention and management plan "explicitly requested location, you must install communications facilities, and the dispatch room with the mine and other departments directly.
Third, you must install pressure air system. All mine ventilation system must be installed. By coal and gas outburst "Coal Mine Safety Regulations" provisions. Other mine according to the daily production needs, combined with disaster prevention, it must be installed on surface pressure air system. Air compressor must be installed on the ground.
Four water supply systems must be installed dust. Mine the main roadway, the park, mining district, Lane and return airway transportation, mining face and the roadway, put coal bunker port, unloading points, and so must "Coal Mine Safety Regulations" requirement laid against dust and water supply pipes.
5, must accurately complete painting "Three Lines" system map. To carefully draw the line with the actual situation of the communication system underground map, press Air hose Road System map and the water supply piping system diagram dust and changes in circumstances promptly filled with paint. Drawings should be accurately labeled mine "three line" telephone, branch, Valve , Refuge chambers, watering points, and so the exact location.
6, to speed up implementation. Have installed "three lines" in various coal mines, all mines should conduct a comprehensive inspection system, on issues identified in time for rectification to ensure the "three lines" intact, smooth and reliable; not install the "three lines" or system imperfect, should be immediately qualified by a corresponding design, construction and installation units and improvement must be completed before the end of the year; new design of infrastructure, expansion and integration of resources to change mine, to include it among the design elements.
Seven, strengthen their guidance. Local authorities in charge of coal mine industry to install "three line" management, to develop "three lines" installation specific requirements and supervision methods. Coal industry administration departments above the county level in accordance with the working relationship, in accordance with the requirements of personnel, strict check on the coal mine, non-conforming, ordered mine immediately for rectification.
