干式充填技术在我国煤矿深井中的应用探讨

摘要

深井采矿存在着巨大的安全隐患，充填采矿法成为深井开采首选的、最安全的、回采率最高的采矿方法。本文主要阐述了干式充填技术的研究现状、作用机理以及干式充填工艺在深井开采中的优点及存在的问题。%Because of potential security risk in deep mining, filling method is preferred and is the safest with the highest recovery rate. The paper presents the research and the mechanism of dry-placed filling with its advantages and disadvantages in deep mining.
