Installation for intensification of extraction and utilization of coal methane

Abstract

A structural performance of equipment for intensification of mining and utilization of coal methane using the technology of pulse injection of water into coal layer which is based on application of hydraulic drive is offered, control is carried out by hydraulic generator of pressure impulses - self-exited two-stage four channels slide-valve. Mathematical dependences for determination of parameters of impulsive stream forming at the output of forcing unit are given and justified, process of penetration of impulse stream of water in the coal layer is considered.
