高溜矿井采用小断面贯通、二次扩帮成井法,集吊罐、井筒留碴涮大和钻孔技术为一体,解决了高天溜井施工难的问题。此法施工进度快,机械结构简单,易组织推广应用,为矿山高天溜井施工开创了新路。 The high-slip mines solved the problem of difficult construction of the high-rise slippery well by adopting the method of small cross-section penetration, secondary expansion and formation of well method, collection of hanging cans, wellbore retention, ballasting, shaving and drilling technology. This method is fast construction progress, mechanical structure is simple, easy to organize the promotion and application of high-pit mine for the mine to open a new road construction.
