At present, there are some places and some units that have serious violations of regulations and risky operations in the management and use of pyrotechnic materials. Specifically in:

1. The supply and demand side of pyrotechnic materials are not healthy.

2. Forced blasting without blasting conditions threatens life safety.

3. The ill-conceived construction method has buried hidden dangers for safe production.

The unit that originally used the pyrotechnic material shall submit the required blasting material consumption plan to the supply unit in advance, and the supply unit shall provide the required items to the user in a timely manner. However, in actual operation, it has appeared:

1 The supply of pyrotechnic materials is not timely, which hinders the normal production.

2 Do not report the blasting material consumption plan, I supply what you do.

In this way, the fire-fighting material consumption unit may occur in violation of the rules and operations without the blasting conditions.

2008 April 24, 2008 and May 10, an open-air iron mine hole blasting, blast hole diameter 80 mm, water resistant non-required blasting explosives. The supply unit provides a bagged water-resistant emulsion explosive with a length of 500 mm and a diameter of 130 mm. The use unit proposed: 1 small hole, thick drug, how to do it? 2 Water-resistant explosives are more expensive than non-water-resistant explosives and are not economical. The leader asked the workers to cut the broken explosives with a knife at the blasting site. This is contrary to the fact that “processing explosives must be carried out at a special site and ironware is not allowed to contact explosives”.

The blasting safety regulations stipulate that the new warehousing equipment should be sampled for performance inspection. However, some mining companies have not tested the performance of new blasting equipment since the use of the pyrotechnic material library. 2 On April 30, 2008, the gunpowder warehouse was unqualified, the plastic bag was damaged, the explosives were outflowed, the weight was insufficient, and even the pyrotechnic materials that did not match the specifications of the explosives supplied to the explosives were issued to the user. 3 On May 11th, 2008, in the same blasting construction operation, the explosives sent to the site were not the same manufacturer, the same production batch number, and the purchased pyrotechnic materials. These are serious violations.

A dynamite warehouse has a capacity of 6,000 kilograms, and in the case of an empty warehouse, 5,000 kilograms of explosives are introduced. On July 21, 2008, the explosives use unit 1,500 kilograms of explosives according to the number of blasting holes. However, the supply unit forced the unit to consume 5,000 kilograms of explosives at one time.

The explosives library is the place to store the pyrotechnic materials. It consumes a lot of explosives from the explosive units and the remaining pyrotechnic materials are stored in the warehouse. Some executive units can do the opposite. Forcing the use of pyrotechnic materials for units using pyrotechnic materials is not allowed to return to the warehouse, causing huge unsafe hidden dangers for blasting construction.

Fortunately, there was no accident in the illegal operation, which paralyzed the employees’ safety ideology. Repeated violations of the regulations have buried hidden dangers for future safe production.

On July 22, 2008, deep hole blasting in an open iron mine required 1,500 kg of explosives. However, the supply unit forced the unit to consume 5,000 kilograms of explosives in the same day. Due to the scattered blasting sites and the small number of gun-filled personnel, it was agreed to adopt a three-time detonation method. As a result, the flying stone fell to the living area, and the branch poles fell to the top of the excavator driver's house. At that time, the family was eating indoors and saw the pointed stones piercing the roof. The table was stuck on the beam of the dining table. The family was scared.

Accident analysis: 1 Due to the tight workload of time, the guns were rushed into the blasthole. This caused the explosives to rise and the filling height was insufficient. 2 Due to the small number of blasting workers in the mine, the neighboring mine blasters came to support the loading of guns. The two teams that first started to work together are not familiar with the working environment, and the habits of working methods are different. There are three holes in the haste filling, and the detonating tube is also installed in the hole. The helper tube that has no choice but to refill is deliberately forgotten because the card hole charge has caused the filling height to be insufficient.

Measures to avoid a serious accident:

1. The blasting process is a course for the mining profession in the university. However, it is not the blasting work that is done for mining. It is suggested that the management of firework products that understand blasting should be added in the public security department, which is beneficial to maintaining public security and promoting economic development.

2. Establish blasting associations and academic organizations, carry out blasting project management, job skills training, on-site technical guidance and Q&A activities, make full use of human resources to serve the society, and push the fireworks management and blasting work to a new stage.

3. Strictly implement safety regulations and “Blasting Safety Regulations”, and resolutely implement the responsibility of managing the responsibility of management. Strict job skills training, adhere to the assessment of the system of holding a certificate. Those who test the law will be investigated for their legal responsibilities.
