摘要
为了研究厚表土层千米埋深矿井开拓设计,实现现代化矿井的安全高效高产,在分析两淮矿区具有代表性的厚表土、高地压、大埋深的口孜东井田地质特征后,从开拓方式、井口位置选择、开采水平划分、开拓大巷布置、采区划分、煤层开采顺序等方面研究了口孜东矿井的开拓设计,该研究成果对厚表土、高地压、大埋深等同类型矿井设计具有一定的指导意义和参考价值。
In order to study the exploitation design of the mine with 1000 m burial depth under thick surface soil layer,and realize the safe and efficient production in modern coal mine,the geological characteristics of Kouzidong mining field are analyzed,which is characterized by the thick topsoil,high ground pressure and large burial depth,and the development design of Kouzidong Mine is studied from the views of development mode,shaft mouth positioning,mining level division,development roadway arrangement,mining district division and mining sequence of coal seams.The research results can provide references for similar mines with thick topsoil,high ground pressure and large buried depth.
