RIG FOR PREVENTING METHANE ACCUMULATION FROM DRAINAGE BOREHOLES INSIDE COAL MINES

Description: The invention belongs to the mining field and refers to an installation for the prevention of methane accumulation originating from drainage boreholes inside coal mines.

The invention belongs to the mining field and refers to an installation for the prevention of methane accumulation originating from drainage boreholes inside coal mines. The presented rig consists of the drainage probe from the core of the mining operation connected through the probe head (1), the hose (2), the spigot (3) to the collecting pipe (4) of the water and methane. Drainage probe from the ceiling of the mining spot is connected through the probe head (5), the hose (6), the spigot (7) to the collector pipe (8) which is connected to the pipe (4) before its connection to the gas separator (10). The pipe (8) is connected to the ceiling of the mine, for support, by a metal element (9). A pipe (13) for transporting methane to the chamber for diluting the methane concentration, (14), is connected to the upper part of the gas separator (10). From the gas separator (10), through the pipe (25), the water is directed into an intermediate tank (26) and later from it through the absorption pipe (27) into a main tank (31) with the help of the pump (29) equipped with automation.
