摘　　要：为了解决隆岩煤矿3101综采工作面回风隅角CO浓度超限问题,通过地面钻孔采用粘土注浆的方法封堵上下采空区裂隙通道,减少上下采空区层间漏风,采用工作面均压通风抑制采空区CO涌出的治理方法来控制3101综采工作面回风隅角CO浓度不超限,保障了3101综采工作面的正常回采,达到了维护煤矿安全生产的作用。In order to solve the problem of CO concentration exceeding the limit in the return air corner of 3101 fully mechanized mining face in Longyan Coal Mine,the clay grouting method is used to block the fissure channel between the upper and lower goafs through the ground drilling,so as to reduce the air leakage between the upper and lower goafs.The treatment method of equal pressure ventilation in the working face to suppress the CO emission in the goaf is used to control the CO concentration in the return air corner of 3101 fully mechanized mining face not to exceed the limit,which ensures the normal mining of 3101 fully mechanized mining face and achieves the effect of maintaining the safe production of coal mine.
