Permeable Wangjialing mine flooding accident found withdrawal were not timely
State Administration of Work Safety, the State Supervision Board of the China Coal Shanxi Coking Coal Mine Co., Ltd. Wangjialing "3? 28" water leakage, determined the incident there is illegal mining construction process violation behavior. Before the accident, there have been flooded mine face signs, construction side and not withdrawn in accordance with regulations in a timely manner and take effective countermeasures.
Confirmed the incident, there ore illegal violation of the construction process behavior
SAWS, the National Coal Board for the supervision of Shanxi Coking Coal Co., Ltd. China Wangjialing Mine "3? 28" water leakage issued a notice that the accident again highlights some of the responsibility in the construction of coal mine safety is not in place to implement , no strict security management, investigation and management of risks such outstanding problems are not serious.
Informed that the accident occurred in the coal mine 20 101 Wangjialing Face wind roadway first, preliminary analysis is driving the process of conduction goaf caused flooding accident.
Accident exposed the main question is:
Mine incident during the construction irregularities violations, did not strictly enforce "the provisions of Mine Water", heading face drilling escape measures are not implemented;
Labor organization and management chaos, in order to catch up schedule in time to progress on duty excavation work in 14 teams working, the operating personnel concentration, and the leading cadres with a class system is not implemented;
Construction safety measures are not implemented, there permeable face signs, no withdrawal in accordance with regulations and to take timely and effective response measures;
Troubleshooting, weak governance, particularly since 20,101 in March this year, face return airway repeatedly found that water tunnel, but has failed to take effective measures to eliminate hidden dangers.
Permeable found signs of withdrawal if the rapid organization of people can avoid accidents
SAWS "Mine Water," which specified that the strict adherence to the "prediction, a suspect must probe, first probe after the excavation, after the adoption of the first rule" principle, once discovered flooding danger, in time threatened by water damage the operation site were evacuated to a safe place, and to take immediate measures to eliminate flooding.
Media coverage for the construction of the project "does not explore the first dig," Sun Shouren Wangjialing Construction Headquarters of mine said that pre-construction project has been commissioned by companies qualified to detect a variety of detection, but may be due to the mining geology situation is more complex, failed to detect water caused the accident.
From at 11:10 on the 28th to 11:50, the construction of mining projects in the coal Wangjialing first deputy director of construction company 63, plates Wangjialing gully coal mine manager Jiang Shijie, has twice received Underground water seepage face has been reported.
Jiang Shijie said at 11:10 on the 28th, an assistant manager on duty after he rose well reported that 27 teams face underground location 800 meters lower right corner of floor in a small amount of seepage; 11:50, 1 Technical Manager Masui name after he reported that the location of 800 meters lower right corner of the water, no pressure, the water is clear, no smell. At that time the presence of a Xian Jiang Shijie coal to ASTRI asked the technical staff, technical staff, said it had carried out surveys of this location, probe reports that can be normal within 820 meters of tunneling.
To 1:40 p.m., Jiang Shijie received a dispatch room telephone, said 27 teams face a flood of; 13:45, Jiang Shijie began asking for an emergency rise to underground wells, but the phone has been able to get through the.
Mine safety experts have found signs of water penetration, and if people can be quickly withdrawn if the Organization is to avoid the accident.
Reporter, some workers argued that on the 25th, operating in 20 101 to 27 teams face some of the workers had found face "pressure charge of the first seam of coal wall and the emergence of smell sweat" to the control center were reported, but no attention.
To drive progress, face too many, drainage, ventilation is not complete
SAWS briefing, said the mine under construction there, "labor organization and management chaos, in order to catch up schedule in time to progress on duty excavation work in 14 teams working, the operating personnel concentration, and the leading cadres with a class system is not implementation "and other outstanding problems.
27 team, said a worker, we will be a time when every day before classes are to progress to speed. Just 78 days before this happens, we go that slow driving classes that day is two meters, the project requires the Department to enter into our daily number of meters. The speed on the happy, do not rate the project on to suppress the Department may not, there is progress on the money.
Worker surnamed Xu, said: "This mine is the excessive production, in order to drive progress, face too much, too much work, but other drainage, ventilation, facilities are not matching. Now there are dozens of underground work surface, according to my experience, these devices need only be for 56 face. "
Self-rescuer became the "decoration", trapped 90% of staff will not use the self-rescuer
Construction side of mine safety management is not strict, but also in the use of self-help device.
In the interview, a worker in Shanxi Yuncheng Ji told reporters: "Yesterday, a reporter asked how to use our self-rescuer? This is really asking us to live, and really do not know how to use self-help devices, said … … but mine self-help devices to receive, but also charge us 300 dollars … … Anyway, carrying on the line you will not use nobody. But the majority of workers to the mine self-rescuer put down after put there, a security officer to check if the re-wear on the on the line. "
A worker is also reflected, trapped in the bottom 90% of staff will not use the self-rescuer, only a few old miners did for many years, things will be met with.
Critical moment of self-help can be life-saving device, turned it into a "decoration."
