Emergency Management published information from the media Yangcheng Evening News that the inspection team of the Central Safety Production Assessment found that some enterprises had problems of emphasizing operation and neglecting safety. One of them is that the slope of the mine transportation road is too steep and there are risky operations. In Chajiashan Quarry, Qingyuan District, Ji'an City, the inspection team found that the steep slope of a section of transportation road in the mining area was too steep, which far exceeded the design slope after on-site measurement.
"The slope of the mine transport road is too steep, and it is easy to cause accidents such as vehicle out of control, sliding or overturning when the fully loaded transport vehicle goes downhill." Experts from the inspection team introduced to reporters. According to Article 9 of the Criteria for Determining Hidden Dangers of Safety Accidents in Metal and Non-metal Mines (Open-pit Mines), it is determined as a major hidden danger of accidents. The problem section collapsed in the rainy season of 2024 and could not be used. The mining enterprise changed its route without authorization, resulting in the slope of the road at the bend exceeding the design slope by 10%. After the diversion, the enterprise did not inform the design unit, the evaluation unit and the supervision department in time.
The open-pit mining enterprise diverted the transportation road, causing the slope of the road to exceed the design slope, and did not inform the design unit, which was revealed as a safety problem by the safety assessment inspection team. That is to say, the enterprise should inform the design unit of the modification of the original design content in the production and operation, and the design unit should make a feasible or infeasible evaluation. Enterprises must not make substantive modifications to the original design content on their own initiative after the acceptance and commissioning of the production line.
This has to be associated with the current hot cement clinker production line to supplement production capacity, it can be said that in addition to a few small supplements, most of them are tens of percent, or even 100%. Production scale is the design basis for various configurations of cement enterprises. To make such a big change in the scale of production line construction, compared with the diversion of mine transportation roads in the above cases, it is really insignificant. We have to ask, has the enterprise with large production capacity informed the design unit?
of registered production capacity and actual production capacity.
