The level el
6、evation of the minefield is from -200m -1200m, the coalfield length on the strike is 8.47km to 10.79km, average 10.18km, the width on the dip is 2.9km on average, the total plane area of the mine is about 29.52km2. There is only one exploring layer_number nine. The coal seam is stable, the coal seam
7、 thickness is 4.5m. Its dip angle is 16 to 24 degree, 22 degree on average. The industry reserves of the mine field are 192.36 million tons and the workable reserves are 124.13 million tons. The average inflow rate in Zhangshuanglou mine is 300 m3/h. The relative gas emission is 0.77m3/t, it is a lo
8、wer gassy mine. The coal dust have a little explosion hazard and self-combustion tendency is 3 to 6 months.The productive capacity of Zhangshuanglou Mine is 1.8 million tons per year，and the service life is 53.0 years. Mine uses shaft and two-level development. The type of mine ventilation system is
9、 central abreast and wings diagonal. The first level is at -575 m, The second level is at -950 m. High cutting mining method is uses by the mine. Main roadway makes use of belt conveyor and bottom-dump wagon to transport coal resource, and mine car to be assistant transport. Mine is working days for
10、 330 days, the net every day to enhance the time 16 hours. Mine system is 3-8 structure.The title of special subject is “Analysis of mine water resource utilization”. The translation part is a treatise about a plasticity model for the behaviour of footings on sand under combined loading.Keywords: sh
