下向胶结充填采矿法的充填参数选择和工艺实施

我国应用下向胶结充填采矿法的主要金属矿山，在充填材料充填参数的选择及充填工艺的实施上各具千秋。本文详细介绍了这些矿山在预埋采场充填小井和回风井、安设充填接顶信号装置、构筑充填密封墙等方面的新技术、新工艺，并进行了简要的评价和建议。

FILLING PARAMETER SELECTION AND TECHNOLOGICAL ENFORCEMENT OF UNDERHAND STOPING WITH CEMENTED FILLING

In China's mines metal using the underhand stoping with cemented filling,the selection of filled material and filling parameters and the fonduct of filling technology were quite different. The author describes the new technique and technology in aspects of fill well and return-air raise prearranged in stope,signal device installed for filling up to roof,eonstruction of filling partition and so on in these mines,and makes a brief assessment and recommen dation.
