海域下煤层综采放顶煤可行性分析与实践

Feasibility Analysis and Practice of Full-mechanized Caving Mining under Sea

海域下煤层采用综放开采在世界海域煤炭开采史上还是首次。从龙口矿区的水文地质条件、覆岩破坏"三带"高度预测和开采设备选型等方面进行了海域开采可行性论证,并对海域首采面综放开采实践情况进行了分析。

It was the first time that full-mechanized caving mining was used under sea in the history of coal mining under sea in the world. Feasibility of mining under sea was analyzed from hydro geological condition, prediction of ＂3-zone＂ height and lectotype of mining equipments. Practice of full-mechanized caving mining was introduced too.
