矿井瓦斯排放方法探讨

Discussion on Discharging Method for Mine Gas

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。

Gas discharging in coal mine is an everyday work, once the wrong methods are taken, a gas explosion will happen. The reasons of gas accumulation must be checked out before discharging gas ,as well as estimating the quantity and density of gas, and the time of discharging gas. It must adhere to the following principles：power off,crowd evacuation, gas content control. Scientific methods of gas dis- charging and strict operation process are the good foundation of ensuring gas discharging safely. The article introduced the gas dischar- ging with sublevels and gas discharging with diatributary,and proposed some matters needing attention during the project process.
