Determination of methane content at Maokhe coal mine from curent mining to -450 level in Vietnam
Abstract
Methane gas is one of the most serious dangers of underground
coal mining as its buildup can lead to methane gas explosion. In
QuangNinh province- Vietnam, several coal mines such as TrangKhe II-III
coal mine, Khe Cham coal mine, especially MaoKhe mine that have high
methane content. At the MaoKhe coal mine,experimental data showed
thatthe concentration of methane in coal seams at different depths were not
similar.In order to ensure safety, this report has been undertaken to
determine a pattern of changing methane contents of coal seams at
different exploitation depths in MaoKhe underground coal mine.
