| Abstract: | In order to master optimal mixing proportion of waste rock that were filled the thin coal seam through the pump.We compared and analyzed the cement and CaO influence on the strength of filling body with different dosage under the condition of different benchmark mixture ratio through a series of uniaxial compressive strength test.Engineering practice shows that the rock movement of C1661 filling work surface was controlled well,and it didn't impact the normal use of buildings and facilities of the surface. |
