ANALYSIS OF FACTORS INFLUENCING ON QUALITY OF FINE SAND CEMENTED FILLING MASS AT JINCHUAN MINE

At Jinchuan Mine′s No.2 mining area and Longshou Mine′s western part,the mined out area backfilling is carried out successfully by using fine sand pipeline filling.Many factors influence on the quality of fine sand cemented filling mass.Based on the test data and experience in the past,this paper analyses the factors influencing on the quality of the filling mass and produces the mathematical regression of reletions between quantifiable factors to provide reference for fine sand filling test in future.
