Liu Yong1,He Guicheng1,2,Yuan Meifang3,Zhang Zhijun1,Ding Dexin1(1.School of Nuclear Resources and Nuclear Fuel Engineering,University of South China, Hengyang,Hunan 421001,China;2.School of Resources and Safety Engineering,Central South University, Changsha 410083,China;3.Hunan Labour Protection Institute of Nonferrous Metals,Changsha 410014,China))  
The ore body in the Baoshan mine is a complicated one and the cut and fill method is to be used to recover it and the cemented waste rock with cement and loess is to be used as the backfill.In order to determine the feasibility of the mixture ratios of the cemented waste rock with cement and loess,the compressive strengths of the backfills with different mixture ratios at different solidification durations were measured using RMT-150B servo-controlled machine for rock testing.Based on the test results,the backfill with C mixture ratio was used to the cut and fill method,and stress measurements were conducted for the backfill.The results show that the failure process of the cemented waste rock with cement and loess was divided into five stages,that the compressive strength of the backfill decreased with the increase of the loess,that the compressive strength and the initial strength of the backfill increased with the decrease of the cement,that the stress of the test stope filled with C mixture ratio was 2.25 MPa and it made up 47.4 percent of the compressive strength of the backfill at the solidification duration of 28 days,that the research results of the backfill with C mixture ratio provided evidence for other stopes.
