Applying Plugging Technology to Fire Prevention of Mining without Coal Pillar

Abstract:

The technology of mining without coal pillar is popular in many mine, though it can improve the recovery rate, it aggravate the air leakage of gob. Because of the ignorance about oxidation in gob, so it is very difficult to know the true value. When we make the test, we find computer can do it that simulation is consistent with reality overall. The article simulate the velocity field and oxygen concentration by finite element method, so divide the ‘three zones’ of gob and analysis the differences before and after plugging, we can see the huge impact of air leakage. So if we want to prevent the Spontaneous Combustion in mining without coal pillar, it is necessary to use the plugging technology.
