摘要：
In order to solve the problem of constant weight model may lead to failure in mine geological environment impact, and the variable weight theory was introduced into the mine geological environment impact assessment. Firstly, the evaluation of mining geological environmental influence analysis model of uncertainty measurement was established according to the characteristics of Hengshan Baiguo region's gypsum mines. The uncertain measurement functions of all indicators were established. Secondly, the variable weight theory was used to improve the index weights which were calculated by Analytic Hierarchy Process. Finally, the risk grade prediction of mine geological environment impact was made according to grade determination based on confidence identification criteria, and it is concluded that mine shallow risk is greater than the middle, middle risk is greater than the deep. The analysis results are consistent with the actual situations. And it also provides a new way for the mine geological environment impact assessment.

摘要：
In this work, series of catalysts like bimetallic oxides and supported ZSM-5 (acid and/or metal), were applied for the synthesis of pyridine and 3-picoline from acrolein diethyl acetal, water and ammonia in a fixed-bed reactor. The results showed that bimetallic oxides and alkaline catalysts exhibited extremely low catalytic activities whereas HZSM-5 had significantly better than MCM-41 and SBA-15. Among kinds of catalysts, the total yield of pyridine and 3-picoline over Mg-ZSM-5 through ion-exchanged process reached the highest.

摘要：
In this paper, the blasting effect's comprehensive evaluation system of open-pit mine was established by using the theory of Analytic Hierarchy Process. The blasting safety, blasting quality and economic benefit are the first class indexes. Flying distance of stone, explosive unit consumption, block size distribution, holes punching and other eight indicators are the second level class index and the weight of each index was calculated. The Cloud Model was used to calculate the digital eigenvalue of each index. The degree of certainty that the indicator belongs to each level was obtained. According to the principle of large degree of certainty, the affiliation level of each factor was obtained. Combined with the weight of each influence index, the comprehensive result of blasting effect about open-pit mine was calculated and the evaluation result was `Good'. The results of blasting evaluation of open-pit mine obtained through this model were consistent with the results of fuzzy evaluation, and coincide with the evaluation of experts, which verifies the feasibility and reliability of Analytic Hierarchy Process and Cloud Model in the evaluation of blasting effect in open-pit mine.

摘要：
In underground uranium mines of China, there are many chamber stopes that can generate and accumulate radon and its daughters, the concentrations of which are about 3-5 times higher than other countries. Therefore, it is very urgent to improve the level of radiation protection of the chamber stopes in China. Ventilation is one of the effective ways to control the concentrations of radon and its daughters. First, this study established the mathematical models that calculated the concentration of radon and its daughters in the chamber stope for designing and optimizing ventilation systems by using the theories of turbulent mass transfer and radioactive decay. Second, the models were used to analyze radon and its daughters' concentrations with the change of airflow rate, air volume, and radon generation rate in chamber stope. Third, the ventilation conditions of chamber stopes of four typical uranium mines in China were investigated and the models to calculate radon and its daughters' concentrations were used to verify its accuracy. Finally, the difference is analyzed between the measured values and the theoretical values of the total Potential Alpha Energy Concentration (PAEC) of radon daughters and a linear correction formula was established.

摘要：
In order to adapt to the narrow space and complex branch in deep mine roadway, which have an adverse impact on the accuracy of nodes localization, a self-localization algorithm for deep mine wireless sensor networks based on MDS-MDS and rigid subset (Rigid-MDS) was proposed. The new distributed algorithm divides whole network into some globally rigid subset based on rigid graph theory, in which nodes have close spatial correlation, less hop and alike path direction with all of other nodes in the same subset, and it reduces the error by shortest path. And afterwards, some boundary nodes close to other subsets is chosen as framework with anchor nodes to locate the whole network. Finally, homogeneous coordinate system is used to make the geometric change. Simulation results show that the Rigid-MDS can reduce error in the roadway branch compared with MDS-MAP.
摘要：
There are not more studies on whether the improved set pair analysis(SPA) could apply to risk assessment of shallow groundwater pollution. In order to make the most of this method, this paper firstly puts forward the pollution risk analysis model according to the pollution process and constructs a risk assessment system of shallow groundwater pollution even associates it with unascertained measure theory and analytic hierarchy process. The analytic hierarchy process is used to determine the weight of each layer; The measure function decides the membership degree of the index layer for calculating the unascertained evaluation matrix of the system layer; The connection number of set pair analysis is linked to the level of pollution risk assessment. The evaluation example is used to identify the feasibility about the method of the improved set pair analysis, and the result is entirely feasible. Moreover, this improved approach shows the actual pollution risk situation.
摘要：
Aiming at the problem of high cost of cable layout and poor maintenance in traditional radioactive pollution monitoring for uranium tailings, considering banded dam and little node connectivity, a weight optimized centroid localization algorithm is proposed. Under different index, by comparing the positioning accuracy and the influence of the external disturbance, new algorithm changes the index of weight and measured distance -1 to -1.5, resulting in an accuracy improvement in long distance. Simulation demonstrated that compared with centroid localization algorithm and maximum likelihood estimation, average positioning error of the new algorithm was reduced by 37.5% and 30.7%, and the maximum positioning error was reduced by 1/5 and by 2/5. With high reliability and stability, the new algorithm can meet the requirements of position in radioactive pollution monitoring for uranium tailings.
摘要：
Dynamic shear modulus and damping ratio are two main parameters for describing the dynamic performance of aeolian soils. This paper presents the influence of the confining pressure, the consolidation ratio and the vibration frequency on the dynamic shear modulus and the damping ratio of aeolian soils with a series of dynamic triaxial tests. Experimental results show that the dynamic shear modulus of aeolian soils increases with the confining pressure and the consolidation ratio, while the damping ratio decreasing with them; both of the dynamic shear modulus and the consolidation ratio increases with the vibration frequency, but the influence is less than that of the confining pressure and the consolidation ratio.
摘要：
In order to optimize the energy-balanced problem and lengthen the network lifetime for Wireless sensor network(WSN) monitoring, a routing protocol that based on monitoring area partition clustering for energy-balanced(EBPC) was proposed. We divided monitoring area into several virtual partitions, controlled the number of common nodes and clusters by data fusion rate, and forwarded cluster heads data to the next partitions with minimum path selection coefficient. Through performance analysis and simulation of EBPC reaches a conclusion that EBPC routing protocol has a superior balance of energy consumption than LEACH and EEUC, when data fusion rate is 0.5, network lifetime lengthen rate well be 1.3, and the effect of EEUC is more obvious when the data fusion rate have a lower value.
摘要：
Total suspended particle (TSP) and fine particulate matter (PM2.5) samples were collected continuously using an atmospheric particulate matter sampler at sampling points in a tailings reservoir in the south from October 28 to November 3, 2013. The mass concentrations of particulate matter in the air, the contents, and morphological analysis of heavy metal elements (Pb, Cd, U, Cu) were also studied. The results indicate that the air particulate matter concentrations exceed the mass concentration limits of national Grade II ambient air quality standard (GB3095-2012); The heavy metals content in air particulate matter from high to low order is: Pb > Cu > U > Cd and heavy metals are easier to be concentrated on fine particulate matter (PM2.5); heavy metal elements (Pb, Cd, Cu) exist mainly in the exchangeable morphology, especially the element Cd.
