摘要
该文主要介绍了枣矿集团田陈煤矿3下7108综放工作面缩面改造的方法和步骤,成功解决了因受断层影响造成工作面反刀把式布置的回采缩面难题,保证了工作面的合理布置和不规则工作面缩面系统改造的高效完成。田陈煤矿3下7108工作面为躲避断层,工作面采用了非常规型布置,为保证生产接续问题,决定工作面在由里向外回采过程中,数次进行工作面若干切眼的合茬对接和缩面改造,实现了连续生产。今介绍其中一次缩面改造的方案。
The article mainly introduced the transformation methods and steps of 3 fully mechamzed top coal cavmg surtace in Tian Chen Coal Mine, Zaozhuang Mining Group, successfully solved the problem caused by mining working face anti Dao arrangement of shrinking face problems, to ensure the efficient completion of rational layout of working face and irregular face shrinking face system. Tian Chen coal mine 3 working face under 7108 is avoid fault, with unconventional arrangement of working surface. In order to ensure the production, mining the working face from the inside to the outside, several working face several close end butting eye and shrinking of the surface modification, realizes continuous production. A shrinking surface modification scheme was introduce in the article.
