Authors: Liu Qin Pu , Guo Yu Ling , Giesy John P.
Published: June 2014

Here is presented the concepts of Fertilization Ecological Hazard Index (FEHI) and Fertilization Ecological Safety Threshold (FEST). These concepts have been used to develop models that assess the hazards posed by fertilization with inorganic fertilizers on ecological environments in China. Based on these models, there were 11 regions, most of which are located in Western China, slightly at risk from over-fertilization, while 14 regions located in central or eastern China were at a moderate hazard from overuse of fertilizers. Six regions in western China were found at ecological safety of environment because of small amounts of fertilizers used in these regions. Ecological safety of environment decreased along the gradient from northwest to southeast by fertilization. There were several factors that influence FEHI. It is obligatory for local governments to offer training to guide reasonable uses of fertilization. It would be prudent for China to establish laws to protect soils, especially to regulate the use of fertilizers in agriculture.

Improved Probabilistic Load Flow Method to Consider Random Generator Outages
Authors: Zhang Chuan Cheng , Yan Cui Hui , Dai Sai , Xu Dan , Zhu Yi , Dong Wei
Published: June 2014

In conventional cumulant method of probabilistic load flow (PLF), random generator outages are usually simulated by discrete distributions of nodal power injections, but that will lead to significant error in AC load flow model. An improved PLF method base on AC model is proposed in this paper, which considers random generator outages and loads uncertainties. Cumulant and Gram-Charlier series expansion were applied to deal with the random variations of loads, instead of convolution calculations. According to the characteristics and focused aspects of power grid, certain generators were selected to form event group of generator outages and each event was analysed by exact load flow.Then total probability theorem was introduced to obtain the probabilistic distributions of node voltages and line flows that considered random factors of loads and generators.The case study of IEEE 39-bus system shows that the random generator outages remarkably affect the probabilistic distributions of state variables. The proposed method can avoid the error caused by generator outages in conventional cumulant method. Furthermore, the result of proposed method is consistent with that of Monte Carlo simulation, while computation speed is much faster.

Preventing tramcar accidents is very important in the production of the coal mine. In this paper, S7-200PLC and BP neural network are used to design a intelligent flexible anti-running system. The control system adopts normally closed and flexible bufferred barrier. Following is the simulation experiment scheme. The BP neural network is adopted to eliminate the influence of temperature and filter by photo-electric coupler, which can measure the accurate and reliable tramcar speed. If the speed is faster than set point, the system will give an alarm and barrier does not work ,which stops the harvesters continuing running. This method guarantees the safe operation of coal mine.

Large loop source TEM method has played an important role in minerals and engineering exploration. But there is a strong border effect when one explains by central loop later-time apparent resistivity. In this paper, a method was used to calculate all-time apparent resistivity by magnetic dipoles composing loop. For 1D forward data, all-time apparent resistivity was computed and compared with later-time apparent resistivity. Conclusions have been drawn that all-time apparent resistivity has no border effect on homogeneous ground model; but for complex layered model, all-time apparent resistivity border effect is reflected in vicinity of false extreme point of apparent resistivity curve, and is much weaker than later-time apparent resistivity border effect. The conclusions are conducive to a correct understanding of using all-time apparent resistivity to eliminate border effect and guide correct interpretation of measurement data.

Based on the self-made triaxial servo-controlled seepage equipment for thermo-hydro-mechanical coupling of coal containing gas, the experimental study on the thickness effect of composite coal and rock containing gas was carried out with the length of composite coal and rocks, confining pressure and gas pressure fixed, meanwhile change the thickness of sandstones and coal. The results show that the strain-stress curve of composite coal and rock containing gas has great identity with the typical strain-stress curve of coal or rock. The thickness effect does exist in the composite coal and rock, different thickness ratios between sandstone on top and coal have different effect on the peak strength of composite coal and rocks. When the ratio of sandstone on top to coal is close to 1.1, the extremum of the peak strength will appear more easily in the condition of the same coal thickness. The strength of composite coal and rocks will fall if the ratio is higher or lower than the ratio of thickness correspondence of the extremum, moreover, the speed of decrease is higher when the sandstone is thinner than the coal. The peak strength of composite coal and rocks varies between the strength of coal and the sandstone. The elasticity modulus of the rock-coal-rock body varies between the coal and sandstone, moreover, an extremum appears more easily when the ratio of sandstone on top to coal is close to 1.1. The poisson's ratios of composite coal and rocks are lower than sandstone, higher than coals. The results have a reference value in the support of half coal crag tunnel and the mechanical features of the composite coal and rocks containing gas.

Sandstone roof water is the direct water-filling resource of coal mining, which has a great effect on the mine production. However, because of the unequal enrichment of Sandstone roof water, it is difficult to prevent and treat sandstone roof water. In order to study the water enrichment of coal roof sandstone, take 8# coal seam of ZhangBei coal mine as an example. Based on the analysis of influencing factors and the establishment of evaluation index system of the enrichment of sandstone roof water, water enrichment of coal roof sandstone was predicted by the use of GRNN. Researches have shown that the influencing factors of water enrichment of roof sandstone include sandstone thickness, mudstone thickness, fracture strength and fracture density. The prediction model of water enrichment of coal roof sandstone based on GRNN has the good ability of prediction and generalization, and the predicted results can provide certain basis for water prevention and treatment of sandstone roof water.
