This paper studied the plotting of the hazard zone of Wulong mine's rockburst. This paper used ANSYS program to set up model then put up stress analysis. Taking the 311 working face of Wulong coal mine as an example, the contours of vertical stresses in the roof and floor are obtained corresponding to the mining distances of 100 m ,200 m ,300 m and 400 m respectively.It is indicated that the magnitude of vertical stress is the important influencing factor of rockburst.

Effects of dry temperature and dry time on properties of heat cured sand and the relationship with binder composition are as follows:sands bonded by binders that are not modified have high strength when dry temperature is high and dry time is long,but their anti-wettability power is poor . Sands bonded by binders that are modified by B but not modified by M can be dried quickly and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M but not modified by B can also be dried quickly to obtain maximum strength,then the strength becomes lower when they are dried continually for more time. and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M as well as by B at the same time can be dried quickly to obtain maximum strength at low temperature and short time. But the anti-wettability of sand mold is best when they are dried at high temperature and long time.
