作者 陈建华 孟凡新 夏永中 《中州煤炭》 2009年第4期89-91,共3页
如果矿井瓦斯排放措施不合理,则易于出现瓦斯爆炸事故。瓦斯排放前,要查明瓦斯积聚的原因,估算积聚的瓦斯量和浓度,估算排放时间,制定瓦斯排放措施。排放过程中坚持停电、撤人和限量的制度,科学合理的瓦斯排放措施和严格的操作过... 如果矿井瓦斯排放措施不合理,则易于出现瓦斯爆炸事故。瓦斯排放前,要查明瓦斯积聚的原因,估算积聚的瓦斯量和浓度,估算排放时间,制定瓦斯排放措施。排放过程中坚持停电、撤人和限量的制度,科学合理的瓦斯排放措施和严格的操作过程,是保障瓦斯排放安全可靠进行的基础。介绍了瓦斯分段排放法和卸流排放法,并提出了技术措施实施过程中应注意的事项。 展开更多
