The system is closely combined with coking production process, deeply integrates intelligent optimization, neural network, coal quality online analysis, radar level monitoring and laser three-dimensional imaging measurement technology. It is an expert system integrating intelligent optimization of coal blending, coke quality prediction, coal yard reserves and quality management, production monitoring and early warning and coking information management platform functions. The coking coal blending expert system can reduce the cost of coal blending, improve the quality of coke, realize all-round production monitoring and abnormal early warning, and reduce the coking cost by 10 yuan / ton under the premise of ensuring the coke quality. It plays an irreplaceable role in improving the economic benefits, improving the production management level and stabilizing the product quality of coking enterprises.
