摘要
立井基岩垮塌是不易见到的，而恩口煤矿立井基岩垮踢事故却很典型。本文应用工程地质力学及岩体力学有关理论进行分析，指出在井筒施工中忽视了工程地质条件的变化，对井筒地压和支护设计也未作重新计算，是造成该井筒基岩严重破坏的主要原因。值得引起同行们的注意并从中吸取教训。图３．表１．参４。
The failing of shaft bedrock is very special, but it's typical for the Enkou mine. This article apply engineering geology and other theories to analyse the problem. The main reason of shaft failure are that ignoring the change of engineering geological condition and not thinking shaft foundation pressure and support design for a second. It is worthy of our attention and drawing a lesson from it. 3figs. 1tab, 4refs.
