APPLICATION RESEARCH ON THE PREDICTION OF TAR YIELD OF DEEP COAL SEAM MINING AREAS BASED ON PSO-BPNN MACHINE LEARNING ALGORITHM

Application research on the prediction of tar yield of deep coal seam mining areas based on PSO-BPNN machine learning algorithm

There are abundant deep coal resources in northern Shaanxi, but the fragile natural environment in this area hinders the large-scale exploitation of oil-rich coal.In-situ thermal conversion of deep animed aniflex complete coal to oil and gas will become an environmentally friendly technology for oil-rich coal mining.Accurate prediction of oil-rich

Evaluation of phosphate rock as the only source of phosphorus for the growth of tall and semi-dwarf durum wheat and rye plants using digital phenotyping

Background Phosphorus nutrition is important for obtaining high yields of crop plants.However, wheat plants are known to be almost incapable of taking up phosphorus from insoluble phosphate sources, and reduced height genes are supposed to decrease this ability further.Methods We performed a pot experiment using Triticum durum Desf.tall spring vari
