Abstract.

A process of dynamics of technological plans for ventilating and degassing of the working areas in the coal mines is considered. It is shown that when inflows of an air-gas mixture are vacuumed and discharged, via the pipeline,  from the top of the face into outside of the working area it makes possible to impact on the aerodynamic process simultaneously in two terms – gas-release control and air-distribution control. Such impact is considered for conditions of basically used ventilation plans. Issues on improving the technology for combined control of the air-distribution and gas-release processes in the working areas are considered. Such improvement provides better efficiency of ventilation due to the redistributed ventilation and degassing in the process of methane discharge into outside of the working area with further methane-air mixture enrichment and utilization.

Keywords:

technological plan of ventilation, degassing of working areas, vacuumization, air distribution.
