【摘要】：结合会东大梁矿业东部高品位矿体充填开采技术经济条件,研发出全粒径碎石泵送充填技术并建立了国内第一套全粒径碎石泵送胶结充填系统。介绍了该充填系统工艺流程及工业试验。结果表明,该系统工艺可行、流程畅通,充填能力可达60~80 m3/h,充填料浆灰砂比1∶4~1∶8可调,充填体3d强度达0.80~1.79 MPa,28d强度达1.92~4.70 MPa,系统及工艺各项指标均能满足大梁矿业上向分层进路充填采矿的要求。
[Abstract]:Combined with the technical and economic conditions of filling and mining of high-grade ore bodies in the eastern part of Huidongdaliang Mining Industry, In this paper, the technology of pumping filling with full diameter crushed stone is developed and the first set of cemented filling system is established in China. The technological process and industrial test of the filling system are introduced. The results show that the technology of the system is feasible and the flow is smooth. The filling capacity can reach 60 ~ 80 m ~ (3 / h), the ratio of slurry to sand is 1: 4 / 1: 8, the 3D strength of the filling body is 0.80 ~ 1.79 MPA / h, and the intensity is 1.92 ~ 4.70 MPA / h. The system and technological indexes can meet the requirements of the upward stratified road filling mining in Deliang mining industry.
