摘要
针对高瓦斯矿井瓦斯涌出量高、治理难度大的实际情况,长平矿在矿井瓦斯治理领域逐渐形成了"优系统、强抽放、细管理和严问责"的"四项原则",系统地从瓦斯的防范、预测及治理等方面进行管理,通过减小巷道通风阻力,运用边采边抽、递进式模块预抽、采空区抽放及地面钻井抽放等一系列综合措施,提高矿井瓦斯抽放率,运用"三进一回"的通风方式,有效遏制了矿井瓦斯事故的发生,控制了矿井的瓦斯超限,保证了安全条件下的高产高效。
According to the practical situation of high gas emission and difficult treatment in high gas mine,four principles of optimum system,strong drainage,meticulous management and strict accountability are gradually formed on gas treatment in Changping coal mine,systematically manages the gas from prevention,prediction and treatment and so on.By reducing roadway ventilation resistance,adopts a series of comprehensive measures such as draining while mining,progressive type module pre -drainage,goaf drainage and surface drilling drainage,improves mine gas drainage rate,utilizes the ventilation method of three intake airflow roadways and one return airway,effectively re-strains the mine gas accident,controls the mine gas limitation,ensures high yield and high efficiency under the safety condition.
