摘要
工作面瓦斯超限是影响煤矿安全生产的重要隐患之一,在现场工作中采用高抽巷来解决工作面瓦斯超限问题。通过现场施工与应用分析,对高抽巷的巷道布置位置、施工过程等方面进行了介绍,对高抽巷技术的应用效果进行了数据分析。实践表明,高抽巷技术的应用是解决工作面瓦斯超限、提高工作面瓦斯抽采率有效途径之一,从而保证了煤矿的安全生产。
Gas overrun in the working face is one of the most important hidden dangers which affect the coal mine safety production. In the field, it always use high level drainage roadway to control gas overrun in the field. Through analysis on the construction and application, as well as the high drainage roadway layout position, construction process are introduced, and data analysis on application effect of high level drainage roadway is made. Practice shows that the application of high drainage technology is one of the most effective ways to solve working face gas overrun, improve working face gas extraction rate. Application of this technology ensures the safety of coal mine production.
