In view of the problems associated with coal powder production in the development of Coalbed Methane (CBM), a fiber fracturing fluid technology is proposed to control pulverized coal production. Based on a force analysis of coal powder in the fracture and the microstructure of fiberproppant, a critical intercepted particle size model of coal powder is established. This model is primarily ...

Most of the absorbed energy is dissipated to change the internal structure of the coal briquette. The more energy that is absorbed, the denser the final coal briquette formed. A high load pressure, long pressing time, and cyclic load can increase the energy absorption of coal powder to improve the density of the reconstituted coal briquette.
