针对赵官煤矿1705工作面的实际情况,根据瓦斯基本参数预测了工作面回采期间的瓦斯涌出量,设计并建立顶板高位钻孔和顺层钻孔组成的瓦斯立体抽采系统,并基于分源治理的原则,提出合理配风和布置风帘等辅助治理措施。 According to the actual situation of No.1705 working face of Zhaoguan Coal Mine, the gas emission during working face recovery is predicted based on gas basic parameters. A gas drainage system composed of high level drilling of top plate and drilling of bedding layer is designed and established. The principle of governance, put forward reasonable allocation of wind and curtain and other auxiliary management measures.
