3.Abstract: The reasonable distribution of mix bulk density and partical size on the transverse and lenghwise direction of sintering pallet,the relationship between segregation index and mix bulk density were discussed.The ways for improving mix bulk density , enhancing mix partical segregation ,decreasing side wall effect and increasing bed surface flatness were proposed.
4.Three-dimensional mechanical performance of primary support under different construction conditions is analyzed by using numerical modeling method. Through four different excavation methods, which are named as curve drift heading, CD, CRD and two-side wall drift heading method, respectively, safety performance of primary support and its effect of confining the wall rock deformation is researched, and the quality of these methods are assessed to recommend proper excavation method for corresponding conditions.
6.Li Zhi used wall of one side man-made ably to differentiate space, still rose to enlarge dimensional effect at the same time; Had this wall, make available face grow in quantity, besides it is commonly used on the wall outside hanging the thing that put a few adornment or uses, li Zhi is returned above made a circle, make each other had communication between area, form connecting visual effect thereby.
