In order to study the support design of large section roadway, filed experiment research of anchor- cable roadway support was carried out, with the engineering background of Zhaozhuang Mine of Jincheng Coal Industry Group. Field monitoring results indicate that, total deformation of Lane5101 is greater than Lane 5102 at the same amount of time, the ribs convergence value of Lane 5101 is 250mm, while Lane5102 is between 130mm to 150mm. The anchor¡¯s anchorage of upper rib is greater than lower rib, and the activity level of rock of upper roadway rib is greater than lower rib. The anchorage of cable at the middle of roof is larger than the sides of roof. The anchorage of cable at the middle of roof floats between 165KN and 168KN, while there is a big difference between the two sides of roof. Geological conditions are the main factors affecting the stability of roadway. The research also shows that the support of bolt and cable integration is an effective method to improve the surrounding rock stability of large section roadway.

Unsupported Ni-Mo composite oxide catalysts were successfully prepared by the sol-gel method with citric acid as a complex agent. The catalysts were characterized using N2adsorption-desorption, X-ray diffraction (XRD) and temperature programmed desorption (NH3-TPD). The effects of Mo/Ni molar ratio and reaction temperature on the hydrodeoxygenation activity of the catalysts were investigated emphatically using acetic acid and phenol as probe compounds. The results showed that the catalysts prepared by the sol-gel method can possess higher specific surface area and the double mesoporous structure. The ¦Â-NiMoO3 phase determined by XRD was existed in the catalysts. For Mo/Ni molar ratios between 0.0 ~ 0.8, the pore volume, the specific surface area, the medium strong acidity and hydrodeoxygenation activity of the catalyst are not monotonically increasing functions of Mo/Ni ratio. The catalyst with Mo/Ni ratio of 0.6 exhibited the highest hydrodeoxygenation activity. At 0.3MPa, the deoxygenation percentage of the phenol was 99.0% at 210¡æand 99.9% at 270¡æ for the acetic acid, respectively.

This paper calculated and analyzed the water requirements of Liuzhou ecological city construction, combining with the eco-city planning of Liuzhou. The results showed that water requirements of Liuzhou ecological city construction was wavelike raised gradually, the water requirements of final ecological city construction will reach100.32¡Á108m3. Development and utilization level of water resources will be 0.406, which the urban, Liujiang, Rongan were 1.529, 0.425 and 0.410 relatively. The water resource was over-exploitation, while water requirement was mainly used for forestland water requirement, agricultural water requirement and industrial water requirement. Therefore, it was vital to save water. The residents¡¯ water consumption and green space water consumption were relatively few, but the increase amplitudes was much higher. Hereby, it is crucial to give some suggestions and measures of water resource conservation and utilization on Liuzhou ecological city construction.

This paper presents coal consumption of electricity generation in China under different energy scenarios of the given long-term energy policies. Long Range Energy Alternatives Planning 2008(LEAP 2008) software is used to develop a simple model of electricity demand and to estimate gross coal consumption of electricity generation in China until2030 under these scenarios. And, time-serial emission inventory of As is also built in the method of emission factors based on fuel consumptions. The results show that the coal consumption will increase by 4 times, amounting to 5.92 billiontces under BAU scenario. The total emission of As is 20.7Mtces with an average annual growth rate of 6.6%. UnderENR scenario, the total reduction of coal consumption and Asemission may reach 25.89% and 26.82% respectively compared to that in BAU scenario.

This paper is devoted to study wind environment in a dense urban areas from the ventilation perspective. In order to take the stochastic characteristics of city wind into consideration, the exceedance probability analysis method was applied using air change rate as the index. The air change rate in the target domain was first obtained using CFD simulation for 16 wind directions and each building pattern. The CFD results demonstrated that airflow fields in the target domain were complicated and the air change rates depends greatly on wind direction. However, there is no direct correlation between street width and air change rate. The exceedance probability distributions were further calculated using the wind statistical data in Tokyo and used to analysis the influences of model orientation and street width. The results indicated that both factors affects the ventilation performance in the target domain significantly. The proposed evaluating approach is useful and effective for the urban ventilation design.

The removal of CODMn, NH4+-N from micro-polluted raw water were investigated by zeolite biological aerated filter process. Several selected test factors such as media height ofBAF£¬hydraulic retention time(HRT)£¬the air/water ratio and concentration of NH4+-N in raw water were studied in the article. The test Results showed that the removal rate of pollutants from the micro-polluted raw water would improve with the increase of media height at the hydraulic retention time of 30min and the air/water ratio of 1:1. CODMn¡¢UV254¡¢turbidity were removed mostly at the foremost height of440mm, and NH4+-N was removed mostly at the height of220~440mm. The average removal rates of CODMn were36.81%, 33.17% and 26.29% respectively at the hydraulic retention time of 15min, 30min and 60min respectively, air/water ratio of 1:1. When the hydraulic retention time is30min, 28.24% of CODMn and 90.57% of NH4+-N were removed at the air/water ratio of 0.5:1, and 31.20% of CODMn and 93.22% of NH4+-N were removed at the air/water ratio of1:1. When the air/water ratio was 2:1, the average removal rates of CODMn and NH4+-N were hardly improved. The appropriate hydraulic retention time and air/water ratio of ZBAF to treat micro-polluted raw Water were 30min and 1:1respectively.

The results shows that the optimum dosage of fly ash, cement, lime, gypsum, CaCl2, Na2SO4 and NaCl is 16g, 3.2g, 1.6g, 0.4g, 0.1g, 0.4g, 0.1g respectively.

Gypsum can provide Ca2+ sources to the system£¬and have the role of dispersant, both of which can make the ingredients of system have a full reaction, but excessive gypsum can reduce the ceramic strength.

In the paper, the biosorption of Pb(II)and Cu(II) ions from contaminated water using a bacterial strain was studied in a batch system. The bacterial strain isolated from heavy metals-contaminated soil was identified as Bacillus sp. The optimum conditions of biosorption were determined. Lead and copper were removed effectively at the concentration that was lower than 100 mg/L. And the concentration of bacteria was also an important factor in removal of heavy metals. The results indicated that the strain Bacillus sp. is a suitablebiosorbent for the removal of Pb(II) and Cu(II) ions from contaminated water.
