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.

Use sodium tetraphenyl boron as indicator to control BAF to extract potassium from Molasses Alcohol Wastewater. When K+ density is lower than 0.003 (mol/l), the bottom of colorimeter tube to be getting white pulverescent precipitate very thin, a small quantity of suspended particle in water. The result is obviously to control BAF absorbed-regenerated course.

A new type of inorganic flocculant, poly silicon boron ferric zinc sulfate (PSBFZ), was synthesized from sodium silicate, ferric sulfate, zinc sulfate and sodium tetra borate by co-polymerization. Comparative flocculation behaviors among poly-aluminium chloride (PAC), poly-ferric sulfate (PFS), poly silicate ferric (PSF) and PSBFZ were explored. The influences of pH, temperature, storage time and dosage on flocculation were studied. The results demonstrate that PSBFZ exhibits the best flocculation performance. Under the optimum conditions, the removal rate of turbidity and chromaticity were up to 99.6%, 99.4%, respectively.

Eight measures of soil and water conservation(SWC) have successfully carried out for developing sustainable agriculture systems in hilly red soil region in southeast China since 2000. Economical, ecological and social benefits are assessed in this study to determine efficiency of these measures. All measures have shown a positive net present value of direct benefits in the computing period when an interest rate 10% used. And an evaluation system for comparing efficiencies of these measures have been built, indictors such us economical effects, payback period time, changes in soil erosion rates, nutrient content, microclimate, and social benefits are recommended. Forest enclosure, embankments, and biomass pools are the most economically measures with a short payback period while low efficiency forest reform, fruit trees planting and shifting slope to terrace measures had remarkable effects on reducing soil erosion and protecting soil and water resource, pear trees can be replaced by other cash crops to avoid long payback period.

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. And, cement and lime can provide an effective alkaline environment to fly ash£¬butexcessive amount of cement and lime will lower the strength of ceramsite. 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. CaCl2, Na2SO4 and NaCl as activating agent, provide a sufficient alkaline environment for the reaction of the initial system, and can efficiently increase the initial strength of ceramsite, so it is helpful for the strength of ceramsite to add some suitable activating agent.
