The monograph deals with the results of experimental and theoretical study of the parameters and regimes of hydraulic transportation of coal through pipelines. The author has discussed the data on the experimental studies of transporting the lump and run-of-mine coal in the water current, the effect of different parameters on the fragmentation of coal in the mains and on their hydroabrasive wear. The problems of theory and the calculation of different flow regimes along pipelines of thinly dispersed highly concentrated water-coal suspensions suitable for direct burning have also been discussed; the structural-mechanical properties of these suspensions and the conditions of transporting lump coal in them have been studied for the first time. Methods have been suggested for the calculation of parameters and regimes of transportation and the change in the sieve composition of coal in mains; recommendations have been made for the selection of effective parameters of transportation which ensure the least energy capacity of the process.
