FIELD: mining industry; removal from mines of mine gas - methane, improvement of safety and gas utilization. SUBSTANCE: the offered plant includes pipeline (casing) installed in hole to connect breakage face with the surface. Pipeline is located in hollow made in upper wall of inclined part of face connected with faces of other mines. Lower end of pipeline is installed in the upper point of inclined mine path of face. Difference in heights of upper and lower points of inclined mine path shall be 3-3.5 m. Installed on the mine surface of the pipeline upper parts is gate and aviation turbine located in the case having holes for air supply to pipe. EFFECT: perfected and simplified plant design, provision of reduction in mine gas of methane content and its increase in place of its withdrawal due to special location of pipeline connecting the face with surface and presence of fire-fighting device, that improves safety of work in mines and possibility of utilization of mixture in capacity of fuel. 1 cl, 2 dwg |
