The location accuracy of traditional methods based on the time difference is always influenced by the iterative method, the initial value and the pre-measured velocity. Solutions are not unique due to the square root calculations. In order to resolve the above two problems, the nonlinear location equations for the time difference of arrivals were simplified to linear equations and an analytical location method without the square root calculations was developed. A set of analytical solutions for AE/microseismic source location (ASS) were proposed for the unknown velocity systems where N=6. Only the coordinates of the sensors and P-wave arrival times are required by the ASS method to accurately solve the source location parameters in real-time situations. The log-logistic distribution was used to determine the microseismic source locations. The blasting tests in the Dongguashan mine were used to verify the proposed analytical method for N≥6. Results show that the location accuracy of the proposed analytical solution is higher than the traditional method. The method highlights four outstanding advantages: no iterative solution; no pre-measured velocity; no initially evaluated source coordinates and no square root calculations. © 2017, Science Press.

The Xuejiping porphyry copper deposit is located in northwestern Yunnan Province, China. Tectonically, it lies in the southern part of the Triassic Yidun island arc. The copper mineralization is mainly hosted in quartz-dioritic and quartz-monzonitic porphyries which intruded into clastic-volcanic rocks of the Late Triassic Tumugou Formation. There are several alteration zones including potassic, strong silicific and phyllic, argillic, and propylitic alteration zones from inner to outer of the mineralized porphyry bodies.The ages of ore-bearing quartz-monzonitic porphyry and its host andesite are obtained by using the zircon SIMS U-Pb dating method, with results of 218.3 ± 1.6. Ma (MSWD = 0.31, N = 15) and 218.5 ± 1.6. Ma (MSWD = 0.91, N = 16), respectively. Meanwhile, the molybdenite Re-Os dating yields a Re-Os isochronal age of 221.4 ± 2.3. Ma (MSWD = 0.54, N = 5) and a weighted mean age of 219.9 ± 0.7. Ma (MSWD = 0.88). They are quite in accordance with the zircon U-Pb ages within errors. Furthermore, all of them are contemporary with the timing of the Garzê-Litang oceanic crust subduction in the Yidun arc. Therefore, the Xuejiping deposit could be formed in a continental margin setting.There are negative ε Nd(t) values ranging from -3.8 to -2.1 and relatively high initial 87Sr/ 86Sr ratios from 0.7051 to 0.7059 for the Xuejiping porphyries and host andesites. The ( 206Pb/ 204Pb) t, ( 207Pb/ 204Pb) t and ( 208Pb/ 204Pb) t values of the Xuejiping porphyries and host andesites vary from 17.899 to 18.654, from 15.529 to 15.626, and from 37.864 to 38.52, respectively, indicative of high radiogenic Pb isotopic features. In situ Hf isotopic analyses on zircons by using LA-MC-ICP-MS exhibit that there are quite uniform and slightly positive ε Hf(t) values ranging from -0.2 to +3.2 (mostly between 0 and +2), corresponding to relatively young single-stage Hf model ages from 735Ma to 871Ma. These isotopic features suggest that the primary magmas of the Xuejiping porphyries and their host andesites were mainly derived from a metasomatized mantle, with contamination of about 5-10% crustal rocks during ascending.Comparing with typical porphyry Cu deposits, the Xuejiping porphyry Cu deposit is distinct by strong silicific and phyllic alteration and major stockwork veining mineralization in the ore-bearing porphyries, but lack of pervasive potassic alteration and disseminated mineralization. This indicates that there could be more prospective Cu resources in the Xuejiping ore district. © 2012 Elsevier Ltd.

Recognition of primary geochemical haloes is one of the most important tools for exploring undiscovered mineral resources. This tool is being routinely applied in exploration programs at the Huanxiangwa gold deposit, Xiong'er Mountains, China. Sampling of unweathered rock for multi-element analysis has been undertaken in all completed and ongoing exploration and development work, including drilling and galleries. Samples have been analyzed for 12 elements (Au, Ag, Pb, Zn, Cu, Mo, As, Sb, Bi, Co, Ni and Ba) from unaltered andesites, altered andesites, altered rocks and mineralized altered rocks. To identify multi-element geochemical associations that can be used to recognize enrichment zones, the lithogeochemical datasets were subjected to centered log-ratio transformation to address the closure problem with compositional data, and the log-ratio transformed datasets were subjected to principal components analysis. Results of analyses show that, in the Huanxiangwa deposit, gold mineralization is characterized by a Au. ± Ag. ± Cu association, base-metal mineralization by a Zn-Pb-Ag-Cu. ± As. ± Sb. ± Mo association, supra- and/or near-ore primary haloes in mineralized altered rocks by an As. ± Sb. ± Bi. ± Ag. ± Au. ± Pb association, sub-ore primary haloes in altered andesites and altered rocks around gold mineralization by a Mo-Bi. ± Sb. ± Ba. ± Zn. ± Ag association, and the host andesites by a Ni-Co-Ba association. Analyses of axial and longitudinal primary haloes indicate that gold mineralization is overprinted base-metal mineralization in the western and deeper parts of the Huanxiangwa deposit. Modified enrichment indices for Au and linear Au productivity values also indicate extension of gold mineralization with base-metal overprint beneath the western parts of the deposit. Based on this, an exploration target zone extending ca. 200. m below the known ore body was delineated, in which the presence of gold mineralization has been successfully verified by drilling. This study concludes that characterization of primary geochemical haloes associated with known deposits, coupled with analysis of linear element productivities, facilitates vectoring toward ore. Characterization of primary haloes associated with known deposits using lithogeochemical data would benefit highly from applications of log-ratio transformations developed for compositional data analysis. © 2012 Elsevier B.V.

In order to solve the difficult problem of pillar extraction safely and efficiently in thin gently inclined ore body, the study of surrounding rock stability is very necessary. Pinglidian mining area of Sanshan Island Gold Mine was studied in this paper. On the basis of site investigation, laboratory rock mechanics test and the mechanical parameter analysis of rock mass, the surrounding rock quality of extracted pillar in thin gently inclined ore body were studied using the RMR classification method, the Q system classification method respectively. Results show that the surrounding rock stability of the stope is average. Also, the roof damage mechanisms of thin gently inclined ore body were analyzed. The rheologic mechanics model of roof was established based on Burgers model, which provides a theoretical basis and reference for roof supporting. In addition, a real-time monitoring system of surrounding rock stress was designed, which works well in pillar extraction in thin gently inclined ore body, and the variation of surrounding rock stress was obtained. The practical application proves that the system has high accuracy and stability.

This work reports an efficient reactor, i.e., oxygen-rich side blow furnace (OSBF), for high-lead slag reduction. An OSBF with a cross-sectional area of 8.4 m2 was applied in an industrial-scale test and the results were compared with those from a traditional high-lead slag reduction reactor, i.e., blast furnace (BF), with which an additional electric heating fore well (EHFW) was connected for slag cleaning. By using the OSBF, Pb and Cu recoveries were raised by 1.07% and 7.99% compared with those from the traditional BF+EHFW, respectively. The optimal slag type for recovering metal values in the OSBF was also analyzed. Within the range of Fe/SiO2 = 1.56–1.87 and CaO/SiO2 = 0.8–1.05, lower Pb and Cu contents of the slag can be achieved with Fe/SiO2 = 1.65–1.75 and CaO/SiO2 = 1.0. © 2014, The Minerals, Metals & Materials Society.

Through 3D numerical analysis of the arching effect between anti-slide piles and soils by FLAC3D software, the process and the mechanism of stress arching effect in the soil were studied. By a series of calculations and comparisons, the influence factors on the soil arching effect were determined. For instance, the space of piles, the mechanical properties of soil (such as internal frictional angle, cohesion, elastic modulus, Poison's ratio and dilation angle of soil) and the interface properties between piles and soils were analyzed in detail. The results show that the soil arch zone will become small and the arch shape will change from arched to parabola with the increase of pile spaces. The internal friction angle, the cohesion and the relative elastic modulus between piles and soil play a positive role in soil arching effects, but the Poisson's ratio plays a negative role. The shear dilation angle has no conspicuous effect on the soil arching. Besides, the soil arch zone will enlarge with the increase of roughness of contact interface between piles and soils.
