Principle of fiber Laser Cutting Machine
The fiber laser cutting machine adopts the international advanced fiber laser to output a high-energy density laser beam, and focuses on the surface of the workpiece, so that the area irradiated by the ultra-fine focus spot on the workpiece is instantly melted and vaporized, and the spot illumination is moved by the numerical control mechanical system. Automatic cutting is achieved. It is a high-tech equipment integrating advanced fiber laser technology, numerical control technology and precision mechanical technology.
Fiber laser cutting machine features
1. Can blow air to cut various metal sheets;
2. High performance, imported original packaged fiber laser, stable performance and long service life;
3. High speed, from efficiency, the speed of cutting thin plates can reach tens of meters per minute;
4. The laser is maintenance free;
5. The cutting edge has good quality, small deformation, flat appearance and beautiful appearance;
6. Adopting imported guiding transmission mechanism and servo motor, the cutting precision is high;
7. It is free to design all kinds of graphics or text for instant cutting, which is simple, flexible and convenient.
Panzhihua coal mine accident caused by 51 people trapped in the well 28 people still have no audio diesel generator | diesel generator price / 2012-08-30
Panzhihua on August 30th from the press conference of Panzhihua City Government Information Office in Sichuan revealed that 51 accident victims were treated in the accident at the Xiaojiawan Coal Mine in the Western District of the city.

The report said that at around 17:00 on August 29, 2012, a gas explosion occurred in the Xiaojiawan coal mine in the west district of Zhengjin Industry and Trade Co., Ltd., Panzhihua City. It was verified that the number of people going down at the time of the accident was 154. There were 104 miners raising wells, and 3 of them died on the way to the hospital. From the evening of the 29th to 6 a.m. on the 30th, rescue workers rescued six survivors from the underground and found 16 dead miners. At present, there are 28 people trapped underground.
After the accident, Panzhihua City dispatched medical staff of 7 medical institutions to the scene for rescue. The Coal Workers’ General Hospital, Panzhihua Iron and Steel Workers General Hospital, Panzhihua City Central Hospital, and Panzhihua City Hospital of Integrated Traditional Chinese and Western Medicine have treated 51 wounded people. 47 of them were mainly carbon monoxide poisoning, and 4 of the wounded were mainly burns, including the critically wounded. There were 7 people and 10 seriously injured people. Most of the wounded were in stable condition.

At about 7 am on the 30th, Yang Dongliang, director of the State Administration of Security Supervision, led the State Council working group to arrive at the accident wellhead. Fu Jianhua also led relevant experts to guide underground rescue operations.
“Because 28 people were trapped in the area where the roadway was cross-section was small and the top of the roadway was serious, plus the carbon monoxide concentration in the area was as high as 1200ppm and the temperature was 80 to 90 degrees Celsius, the ambulance crew passed the ventilator through difficulty.†Related personnel of the rescue command said that the ventilation system was damaged Afterwards, in view of the complex underground conditions, in order to prevent the occurrence of secondary explosions, ventilation systems and air volume cannot be adjusted temporarily during downhole investigations and search and rescue. Therefore, it is difficult to rapidly reduce the concentration of harmful gases in the disaster area. Except for ambulance personnel, other personnel cannot enter the underground facilities. Rescue, rescue is very difficult.
As of 12:00 noon on the 30th, the on-site rescue headquarters had mobilized 139 rescue teams and established a base command post underground. It had organized 21 team searches and completed 70% of the underground roadway search and rescue missions.
