摘要

甲烷气体是地下煤矿开采中最严重的危害之一，其积聚可能导致甲烷气体爆炸。越南秦宁省，TrangKhe ii - iii煤矿、Khe Cham煤矿等几个煤矿，特别是MaoKhe煤矿甲烷含量较高。在茂河煤矿，实验数据表明，不同深度煤层中甲烷浓度不相似。为了确保安全，本报告确定了茂河地下煤矿不同开采深度煤层甲烷含量的变化规律。

Determination of methane content at Maokhe coal mine from curent mining to -450 level in Vietnam

Methane gas is one of the most serious dangers of undergroundcoal mining as its buildup can lead to methane gas explosion. InQuangNinh province- Vietnam, several coal mines such as TrangKhe II-IIIcoal mine, Khe Cham coal mine, especially MaoKhe mine that have highmethane content. At the MaoKhe coal mine,experimental data showedthatthe concentration of methane in coal seams at different depths were notsimilar.In order to ensure safety, this report has been undertaken todetermine a pattern of changing methane contents of coal seams atdifferent exploitation depths in MaoKhe underground coal mine.
