coal gangue, as a solid waste generated during coal mining and washing, not only encroaches on a large number of land resources but also poses certain risks to the environment. It is reported that the cumulative amount of coal gangue piled up in china has reached billion tons, and the annual discharge amount is about million tons.It has two principal applications: the preconcentration of minerals, that is, the rejection of gangue prior to grinding for final liberation, and in coal preparation to produce a commercially graded end-product, that is, clean coal being separated from the heavier shale or high-ash coal.
the coal gangue came from the solid waste produced in daizhuang coal mine and was carried by secondary crushing. most of the gangue was between 0.1 and 13.2 mm, and only a few of them reach 2025 mm. laboratory tap water was selected for experiments.fixed carbon content is an important factor in measuring the carbon content of gangue, which is important for monitoring the spontaneous combustion of gangue and reusing coal gangue resources. although traditional measurement methods of fixed carbon content, such as chemical tests, can achieve high accuracy, meeting the actual needs of mines via these tests is difficult because the measurement
the purpose of this study is to investigate the displacement of coal gangue filling material in road construction and microstructural behavior of treated coal gangue by considering the environmental factors of aqueous solutions with different acidity. the displacement analysis of the coal gangue embankment model has been done by means of the finite element method plaxis.technology is changing the live music industry. those who stay ahead of the curve have a huge opportunity to impress fans, simplify their work, and increase profit. so, how can you get smarter about using concert technology to produce and promote live shows? find out in this new report, with predictions from music and technology leaders. youll hear from the experts at facebook events
