摘要
目前对深矿井的概念和临界深度问题没有取得共识,这给探讨矿山深部开采遇到的地质灾害等问题带来了不便。在通过厘清深矿井分类历史的基础上,对我国煤矿深部开采中遇到的高地温、冲击地压、瓦斯涌出、奥陶纪灰岩突水和采动效应的影响等问题的研究,提出深矿井概念及其分类原则：基于不同煤矿有不同的地质条件、采煤方法、支护方式等,提出深矿井的分类与临界深度应该是一个区间的概念,在此基础上,提出了深矿井的上限为600~800 m,而800~1 200和1 200 m以上深为其2亚类的方案。
Due to no common agreement on the conception and critical depth issue of the deep mine,there would be inconveniences in the discussion on the geological disasters occurred from the deep mining operations.Based on the clarification of the mine classification history,the paper had a study on the high earth temperature,strata bumping,gas emission,the water inrush from the limestone in the Ordovician Period,the mining effect and other issues occurred from the deep mining operations in China coal mines.The paper proposed the deep mine conception and classification principle.Based on the different geological conditions,mining methods,support method and others in different coal mines,the deep mine classification and critical depth proposed shall be a interval conception.Based on the circumstances,the up limit of the deep mine shall be 600~800 m.The depth of 800~1 200 m and over 1 200 m would be two sub alternatives.
