摘要
马兰煤矿10610工作面回采期间瓦斯涌出量超限,其中绝对瓦斯涌出量达到了32 m^3/min,严重制约着矿井的正常安全生产。本文通过现场监测的手段对工作面瓦斯的分布特征及来源进行了研究,并在此基础上提出了相应的措施对其进行治理,工程应用结果表明该治理措施可以有效降低工作面瓦斯浓度,满足矿井的正常安全生产。
In 10610 working face of Malan coal mine,the gas emission exceeds the limit,and the absolute gas emission reaches 32 m^3/min,which seriously restricts the normal safety production of the mine.In this paper,through the means of field monitoring,the distribution characteristics and sources of gas in the working face are studied,and on this basis,the corresponding measures are put forward to control it.The engineering application results show that the control measures can effectively reduce the gas concentration in the working face and meet the normal safety production of the mine.
