近年来,煤矿井下随着每天生产时间的增长,工作面产量也随之上升,人们对工作面进行煤层注水的要求日益提高。 假如工作面的煤层注水确实有效,那就应该大力采用现有的工作面注水技术,同时也要进一步试验工作面长钻孔注水。顺槽注水的应用只能局限于后退式开采工作面和“Z”字形工作面,而连续注水是目前所掌握的方法中最为有效的方法。 鉴于工作面注水的难处及顺槽连续注水的优点,在推进工作面的超前顺槽当前正在试验一种类似于顺槽注水的注水方法。本文叙述了这种方法,并指出了它的发展动向。 在西德,采用远距离超前注水的可能性非常小,本文也将说明其原因。
In recent years, with the daily production time of coal mines increasing, the production of working face has also risen, and people are increasingly demanding the coal seam water injection on the working face. If the face of the coal seam water injection is indeed effective, it should vigorously use the existing face injection technology, but also to further test the face long hole injection. Application of cistern water injection can only be limited to the back-mining face and “Z” shaped face, and continuous water injection is currently the most effective method of control methods. In view of the difficulty of filling the face and the advantages of continuous watering, a water-filling method similar to pouring water is currently being tested at the advanced run of the advancing face. This paper describes this method and points out its development trend. In West Germany, the possibility of using long-range leading water injection is very small, this article will also explain the reason.
