摘要
针对长春兴煤矿采煤工作面在回采期间出现的上隅角瓦斯浓度高、治理难度大问题,对采煤工作面通风系统进行了优化,将原来采煤工作面使用的U型通风系统改变为W型通风系统。应用实践表明,优化后的W型通风系统成功解决了采煤工作面上隅角瓦斯浓度高、瓦斯容易积聚的现象,瓦斯治理效果明显。
In response to the problem of high gas concentration in the upper corner and difficulty in control during the mining process of the coal face in Changchun Xing Coal Mine,the ventilation system of the coal face was optimized,and the original U-shaped ventilation system used in the coal face was changed to a W-shaped ventilation system.The application practice shows that the optimized W-type ventilation system has successfully solved the problem of high gas concentration and easy gas accumulation in the upper corner of the coal mining face,and the gas control effect is obvious.
