综放工作面初采期间的瓦斯治理

为了防止高瓦斯矿井综放工作面初采期间工作面回风流、上隅角瓦斯浓度超限,通过强化采前瓦斯抽采,改进采中、采后瓦斯抽采手段,并采取合理有效的瓦斯抽采措施,解决了综放工作面初采期间的瓦斯治理难题,确保了工作面的安全和高产高效。

Gas Control during Initial Mining in Fully Mechanized Caving Face

In order to prevent the gas concentration of the return air flow and the upper corner of the working face from exceed-ing the limit during the initial mining period of the fully mechanized caving face in high-concentration gas mine,by strengthening the gas drainage before mining,improving the gas drainage means during mining and after mining,and by taking reasonable and effective gas drainage measures,the gas governance problems during the initial mining period of the fully mechanized caving face were solved,and the safety,high yield and high efficiency of the working face were ensured.
