摘要
以云南锡业集团公司块石水泥浆胶结充填采矿法为例,阐述了实际生产试验中,对块石水泥浆胶结充填工艺的实施和充填工艺参数的控制,使充填体强度达到1.5~7.2MPa,满足采矿所需强度和自立高度的要求,实现了"深、小、富"矿体的安全高效回采。
Taking the cemented filling method in Yunnan Tin Group as an example,the cemented filling technology with lump rock and the control of filling parameters were introduced during production tests.The strength of filling body was achieved 1.5~7.2MPa,which met the requirements of mining and self-standing height,and realized safe and efficient stoping of the deep,small and rich orebody.
