(Banpo village white Yaocun) underground coal and gas outburst accident occurred, causing the ground Vice wellhead Explosion Has resulted in two deaths and one injury. As at 3:10 on the April 1, rescue and relief work has made important progress. 29 has been found to rescue trapped successfully, out of danger. Currently there are a large number of trapped underground, the specific number is temporarily unavailable statistics.

Accident is a lesson worth pondering. Before the accident, we can do security in order to achieve "preventive measures" to detect, prevent mining accidents occurred purposes. After the accident, we also have a security device which can be "too late"? Life will continue in the future, we security industry for coal mine Security Production in something?
How to take preventive measures In related news, the mine explosion, the mine mouth and the surrounding buildings were severely Damage And kindled a fire, explosion also damaged a high voltage power line to the mine and power around the four villages, not far from the explosion of a retail outlet sales by all Zhata, including its family of three was pressed.
The mine, after a preliminary analysis, the main reason for this accident are: underground coal and gas outburst accident occurred, causing the ground Vice wellhead explosion. And the time of the accident, to change during the coal mine is still in the business for rectification, a breach on the production of that. The accident exposed Enterprise Mining layout is unreasonable, mine-site management and labor organizations, confusion, super strength of organization of production, Ventilation System complexity, resilience weak, imperfect emergency plan, reflecting the corporate safety responsibilities are not implemented, troubleshooting, not seriously, not completely, thus brewing the accident.
Grim coal mine gas Alarm Systems become increasingly important
With the strengthening of national regulators, the mines have been started related to security systems, in order to achieve " Prevention In the first place ", to detect, prevent occurrence of the purpose of mine. Well, security system, you really can achieve the desired results? It in the end what for coal mine safety? Actual implementation is how what? From the recent frequent mine we do not hard to imagine, now mine is a serious security situation.
General, includes an overview of coal mine safety monitoring system for production safety, video surveillance management system, gas inspection management system, staff time and attendance management system into the well, mine personnel positioning system, underground communication systems. However, these systems are many subsystems are related to coal mine automation and associated information. According to "Coal Mine Safety Monitoring System General technical requirements (AQ6201? 2006)" the provisions of safety detection alarm system, video monitoring and management systems and underground communications system is essential subsystem. But, for now, is not currently installed in each mine have these systems.
For the cause of the accident, if the coal side of prevention, early detection alarm system, installation of production safety, gas management systems and other security equipment inspection; provincial and even national security if the production sector in the safety survey, early detection of these problems and urge the mine as soon as possible to take security measures likely will avoid the tragedy.
Under "Coal Mine Safety Monitoring System for General technical requirements for (AQ6201-2006)" the provisions of safety detection alarm system, video monitoring and management systems and underground communications system is required. Gas alarm systems, on the acquisition probe coal mine gas concentration, air and return air velocity, carbon monoxide concentration, Bureau fan stopped status to open real-time data acquisition, and simultaneously transmitted to the control center, control center for data screening, such as unusual to the Police, and the data according to different constraints, different plans to deal with. The mine incident, we can see the importance of gas alarm systems.
