“…Especially, the geophone array plays a key role in the system as it determines whether the system could work effectively. However, there are few references regarding how the array affects the precision and the reliability of the system and optimization of the geophone array [7,8]. Therefore, an urgent research is needed on the subject [9][10][11][12].…”

Abstract:In order to make the seismic positioning and monitoring system work more effectively, this paper designs four kinds of geophone array methods. By establishing complex geological model and using micro-grid ray tracing, the process that the signal starts from the source location to the seismic geophone arrays is simulated in forward algorithm. In condition of random disturbance, the source location is retrieved by means of inversion algorithm fulfilled by neural network algorithm and genetic algorithm. Finally, on the basis of the analysis of the result and comparison with the true location, the characteristics of every geophone array method are presented. The paper also discusses proper number of geophones in the every array method. Results show that the most accurate, reasonable and effective array method can be selected and the forward and inversion algorithm is also effective.

The article introduces results of studying the problem areas in filling masses of iron ore mining-and-processing enterprise. Some basic study of back filling after the blast hole drilling has been conducted by the authors. The samples picked from the disrupted back filling have been studied for strength. The analysis of the results evidences that all the samples meet the requirements of the strength class but there is a variation of the strength characteristics which evidences about the massif inhomogenuity. The results of chemical, X-ray and fluorescent analyses proved high inhomogenuity of solidified back filling masses in the massif. The microstructure of the back filling samples has inhomogeneous structure, with a great number of various pores. A set of studies showed lack of uniformity and consolidation of the filling solution. It resulted in the loss of strength and durability of the back filling area. The analysis of possible reasons for negative results has been given. The activities to improve the quality and durability of the back filling for mines have been suggested.
