“先抽后采”是煤矿企业瓦斯治理的主要措施之一。在煤矿瓦斯治理中,采取“先抽后采”的治理措施,不仅可以有效保障煤矿瓦斯生产安全,还能进一步加强对煤矿瓦斯开采安全的管理,促进煤矿瓦斯生产发展。本文分析了煤矿瓦斯治理中的“先抽后采”的实践方法,阐述了“先抽后采”的重要意义等,希望对进一步提高“先抽后采”技术提供帮助。
“Pumping after the first mining ” is one of the main measures of coal mine gas management. In the management of coal mine gas, adopting the management measures of “pumping first and collecting afterwards” can not only effectively guarantee the safety of gas production in coal mines, but also further strengthen the management of gas safety in coal mines and promote the development of gas production in coal mines. This paper analyzes the practice of “pumping first and then collecting” in the management of gas in coal mine and expounds the significance of “pumping first and then pumping”, hoping to help to further improve the technology of “pumping first and then pumping” .
